103-799: Horn Island , or Ngurupai/Narupai (pronounced Nœrupai/Nurupai ) in the local language, is an island of the Torres Strait Islands archipelago located in the Torres Strait , in Queensland in Northern Australia between the Australian mainland and Papua New Guinea . It is within the locality of Horn within the Shire of Torres ; the boundaries of the locality include the island itself and surrounding waters of
206-451: A "commuting" distance to an island that has enough resources to be sustainable. The presence of an island is marked by seabirds , differences in cloud and weather patterns, as well as changes in the direction of waves. It is also possible for human populations to have gone extinct on islands, evidenced by explorers finding islands that show evidence of habitation but no life. Not all islands were or are inhabited by maritime cultures. In
309-514: A "rafting event". This phenomenon is known as oceanic dispersal . Tropical storms have the capacity to transport species over great distances. Animals like tortoises can live for weeks without food or water, and are able to survive floating on debris in the sea. One case study showed that in 1995, fifteen iguanas survived a 300 km journey to Anguilla in the Caribbean , an island which no iguana had lived on previously. They survived floating on
412-594: A census was held simultaneously in each of the colonies. This was part of a census of the British Empire . The questions posed in the colonies were not uniform and Henry Heylyn Hayter , who conducted the Victorian census, found that this caused difficulties in dealing with Australia-wide data. The population of Australia counted in the census was 2,231,531. At the time, the Northern Territory
515-426: A detailed review of 1,288 islands found that they were home to 1,189 highly-threatened vertebrate species, which was 41 percent of the global figure. Coral bleaching is expected to occur with more frequency, threatening marine ecosystems, some of which island economies are dependent on. Some islands that are low-lying may cease to exist given high enough amounts of sea level rise. Tuvalu received media attention for
618-614: A few meters high, and are usually temporary. Changes in the flow speed, water level, and sediment content of the river may effect the rate of fluvial island formation and depletion. Permanent river islands also exist, the largest of which (that is completely inland) is Bananal Island in the Tocantins of Brazil, which has a maximum width of 55 kilometers. Lakes form for a variety of reasons, including glaciers , plate tectonics, and volcanism. Lake islands can form as part of these processes. The field of insular biogeography studies
721-402: A higher carrying capacity also have more genetic diversity , which promotes speciation . Oceanic islands, ones that have never been connected to shore, are only populated by life that can cross the sea. This means that any animals present on the island had to have flown there, in the case of birds or bats , were carried by such animals, or were carried in a sea current in what is known as
824-577: A letter. Contrary to previous years where censuses were both delivered and retrieved from households by dedicated census employees, in 2016 most of the paperwork relating to the census was delivered from and to the ABS by Australia Post . The 2016 census was met by two controversies. The first was that the retention of names and addresses increased to up to 4 years, from 18 months in the 2006 and 2011 censuses, leading to concerns about privacy and data security. As such, some Australian Senate crossbenchers (from
927-477: A loss of almost all the infrastructure in Dominica. Sea level rise and other climate changes can reduce freshwater reserves, resulting in droughts . These risks are expected to decrease the habitability of islands, especially small ones. Beyond risks to human life, plant and animal life are threatened. It has been estimated that almost 50 percent of land species threatened by extinction live on islands. In 2017,
1030-403: A mass of uprooted trees from a storm. Plant species are thought to be able to travel great distances of ocean. New Zealand and Australia share 200 native plant species, despite being separated by 1500 km. Continental islands, islands that were at one point connected to a continent, are expected to share a common history of plant and animal life up until the point that the island broke away from
1133-837: A minimum. Some islands became host to humans due to a land bridge or a continental island splitting from the mainland. Today, up to 10% of the world's population lives on islands. Islands are popular targets for tourism due to their perceived natural beauty, isolation, and unique cultures. Islands became the target of colonization by Europeans, resulting in the majority of islands in the Pacific being put under European control. Decolonization has resulted in some but not all island nations becoming self-governing , with lasting effects related to industrialisation , invasive species , nuclear weapons testing , and tourism . Islands and island countries are threatened by climate change . Sea level rise threatens to submerge nations such as Maldives ,
SECTION 10
#17327901143471236-743: A minority. Cultural attitudes related to communal ownership of land as well as a lack of individualistic decision-making may make some island cultures less compatible with the global capitalist economy, causing these nations to experience less economic growth. Islands have long been a popular target for tourism , thanks to their unique climates, cultures, and natural beauty. However, islands may suffer from poor transportation connectivity from airplanes and boats and strains on infrastructure from tourist activity. Islands in colder climates often rely on seasonal tourists seeking to enjoy nature or local cultures, and may only be one aspect of an island's economy. In contrast, tourism on tropical islands can often make up
1339-613: A permanent caisson , a steel or concrete structure built in a closed loop and then filled with sand. Some modern islands have been constructed by pouring millions of tons of sand into the sea, such as with Pearl Island in Qatar or the Palm Islands in Dubai. These islands are usually created for real estate development , and are sold for private ownership or construction of housing. Offshore oil platforms have also been described as
1442-524: A phenomenon where new oceanic crust is formed, pushing away older crust. Islands sitting on the continental shelf may be called continental islands. Other islands, like those that make up New Zealand , are what remains of continents that shrank and sunk beneath the sea. It was estimated that Zealandia , the continent-like area of crust that New Zealand sits on, has had 93% of its original surface area submerged. Some islands are formed when coral reefs grow on volcanic islands that have submerged beneath
1545-437: A population of 539 people. In the 2016 census , Horn had a population of 531 people. In the 2021 census , Horn had a population of 533 people. Horn Island has a very warm tropical savanna climate ( Aw ) with consistently hot temperatures all year round. The wet season lasts from December to April and features high humidity and frequent heavy downpours. Horn Island is occasionally affected by tropical cyclones ; however it
1648-423: A press conference publicizing the ongoing submerging of the island country. Tuvalu signed a cooperation agreement with Australia agreeing to annually allow 280 of its citizens to become permanent residents of Australia. The Marshall Islands, a country of 1,156 islands, have also been identified as a country that may be existentially threatened by rising seas. Increasing intensity of tropical storms also increases
1751-483: A priority target of conservation efforts, to prevent the extinction of these species. Despite high levels of endemism, the total species richness , the total number of unique species in a region, is lower on islands than on mainlands. The level of species richness on islands is proportional to the area of that island, a phenomenon known as the species-area relationship . This is because larger areas have more resources and thus can support more organisms. Populations with
1854-593: A provision (section 127), which said: "In reckoning the numbers of the people of the Commonwealth, or of a State or other part of the Commonwealth, Aboriginal [persons ...] shall not be counted." In 1967, a referendum was held which approved two amendments to the Australian constitution relating to Indigenous Australians. The second of the two amendments deleted section 127 from the Constitution. It
1957-411: A restricted set of natural resources. However, these nations control some of the largest fisheries in the world, deposits of copper , gold , and nickel , as well as oil deposits . The natural beauty of island nations also makes them a magnet for tourism . Islands also have geopolitical value for naval bases , weapons testing , and general territorial control. One such example is French Polynesia ,
2060-476: A selection pressure for smaller animals that require less food. Having fewer predators would mean these animals did not need not be large to survive. Charles Darwin formulated the theory of natural selection through the study of island ecology. The species he observed on the Galápagos Islands , including tanager birds, contributed to his understanding of how evolution works. He first traveled to
2163-465: A short while, until the government relocated the Kaurareg to Hammond Island (Kœriri), where they remained until 1922. These islands (along with the other islands in the group) are the lands of the Kaurareg, each island – or parts thereof – owned by different clans. The language of the Kaurareg is Kala Lagaw Ya , in the form of Kaiwalgau Ya (called Kauraraigau Ya [colloquial variant Kauraregau Ya] in
SECTION 20
#17327901143472266-509: A specific property known as adaptive radiation . In this process, a species that arrives on a group of islands rapidly becomes more diverse over time, splitting off into new species or subspecies. A species that reaches an island ecosystem may face little competition for resources, or may find that the resources that they found in their previous habitat are not available. These factors together result in individual evolutionary branches with different means of survival. The classical example of this
2369-414: A territory that receives substantial military expenditure and aid from France. Since the first discoveries of Polynesian, Micronesian , and other islands by Westerners, these nations have been the subject of colonization. Islands were the target of Christian missionaries . These missionaries faced resistance, but found success when some local chiefs used European support to centralize power. Beginning in
2472-519: A tree that is present in Australia, New Zealand, parts of South American, and New Guinea, places that today are geographically distant. A possible explanation for this phenomenon is that these landmasses were once all part of the continent Gondwana and separated by tectonic drift. However, there are competing theories that suggest this species may have reached faraway places by way of oceanic dispersal. Species that colonize island archipelagos exhibit
2575-616: A type of island. Some atolls have been covered in concrete to create artificial islands for military purposes, such as those created by China in the South China Sea . These atolls were previously low-tide elevations, landmasses that are only above water during low tide . The United Nations Convention on the Law of the Sea indicates that these islands may not have the same legal status as a naturally occurring island, and as such may not confer
2678-515: Is Darwin's finches , a group of up to fifteen tanager species that are endemic to the Galápagos Islands. These birds evolved different beaks in order to eat different kinds of food available on the islands. The large ground finch has a large bill used to crack seeds and eat fruit. The Genovesa cactus finch prefers cacti as a food source, and has a beak adapted for removing pulp and flowers from cacti. The green warbler-finch (in
2781-525: Is a gateway for travellers to the mainland and outer islands. The present-day population consists of islanders drawn from all islands of the Torres Strait, as well as non-islanders. Residents travel daily by ferry across the Ellis Channel to Thursday Island for work and school. Shire of Torres is the local government authority, providing the island community's municipal services. Horn Island
2884-598: Is actually a cognate of Swedish ö and German Aue , and more distantly related to Latin aqua (water). The spelling of the word was modified in the 15th century because of a false etymology caused by an association with the Old French loanword isle , which itself comes from the Latin word insula . Islands often are found in archipelagos or island chains, which are collections of islands. These chains are thought to form from volcanic hotspots , areas of

Also during World War II the Horn Island Seaplane Base was built. Church influence was the London Missionary Society up until 1915 when the Anglican Church assumed responsibility. In 1946, some of the Kaurareg (Nœrupai) people moved back from Kubin on Moa Island to Horn and settled here in present-day Wasaga Village at
3193-1083: Is in Outie Street. It is within the Thursday Island Parish of the Roman Catholic Diocese of Cairns . Island An island or isle is a piece of land, distinct from a continent, completely surrounded by water. There are continental islands, which were formed by being split from a continent by plate tectonics , and oceanic islands, which have never been part of a continent. Oceanic islands can be formed from volcanic activity, grow into atolls from coral reefs , and form from sediment along shorelines, creating barrier islands . River islands can also form from sediment and debris in rivers. Artificial islands are those made by humans, including small rocky outcroppings built out of lagoons and large-scale land reclamation projects used for development. Islands are host to diverse plant and animal life. Oceanic islands have

The town of Wasaga was named on 1 April 1971 by the Queensland Place Names Board after Wasaga Billy, the first leader of the Horn Island community. After the 1871 massacre on Prince of Wales Island (Muralag), remnants of the people settled here for

These species compete for resources with native animals, and some may grow so densely that they displace other forms of existing life. For hundreds of years, islands have been created through land reclamation . One of the first recorded instances of this when people of

Larger animals such as the hippopotamus tend to become smaller, such as in the case of the pygmy hippopotamus . This is known as insular dwarfism . In the case of smaller animals, it has been hypothesized that animals on islands may have fewer predators and competitors, resulting in selection pressure towards larger animals. Larger animals may exhaust food resources quickly due to their size, causing malnutrition in their young, resulting in

Every person must complete the census, although some personal questions are not compulsory. The penalty for failing to complete the census after being directed to by the Australian Statistician is one federal penalty unit , or A$ 220 .

These historians theorize that successful explorers were rewarded with recognition and wealth, leading others to attempt possibly dangerous expeditions to discover more islands, usually with poor results. About 10% of the world's population lives on islands. The study of the culture of islands is known as island studies . The interest in

4326-507: The Polynesians . Many of the previous island settlements required traveling distances of less than 100 km (62 mi), whereas Polynesians may have traveled 2,000–3,200 km (1,200–2,000 mi) to settle islands such as Tahiti . They would send navigators to sail the ocean without the aid of navigational instruments to discover new islands for settlement. Between 1100 and 800 BC, Polynesians sailed East from New Guinea and
4429-891: The Solomon Islands and reached the islands that make up the modern-day Fiji and Samoa . The furthest extent of this migration would be Easter Island in the East, and New Zealand in the South, with New Zealand's first settlements between 1250 and 1300. Historians have sought to understand why some remote islands have always been uninhabited, while others, especially in the Pacific Ocean , have long been populated by humans. Generally, larger islands are more likely to be able to sustain humans and thus are more likely to have been settled. Small islands that cannot sustain populations on their own can still be habitable if they are within
4532-499: The Solomon Islands created eighty such islands by piling coral and rock in the Lau Lagoon . One traditional way of constructing islands is with the use of a revetment . Sandbags or stones are dropped with a barge into the sea to bring the land level slightly out of the water. The island area is then filled with sand or gravel, followed by a construction of this revetment to hold it together. Islands have also been constructed with
4635-414: The lithosphere where the mantle is hotter than the surrounding area. These hotspots would give rise to volcanoes whose lava would form the rock the islands are made of. For some islands, the movement of tectonic plates above stationary hotspots would form islands in a linear chain, with the islands further away from the hotspot being progressively older and more eroded , before disappearing under
4738-450: The sea as a natural barrier to the introduction of new species, causing the species that do reach the island to evolve in isolation. Continental islands share animal and plant life with the continent they split from. Depending on how long ago the continental island formed, the life on that island may have diverged greatly from the mainland due to natural selection . Humans have lived on and traveled between islands for thousands of years at

In the early 20th century, a town flourished as a result of the pearling industry, but declined when non-islander residents were evacuated to southern Queensland during World War II . A major Allied airbase, known as Horn Island Aerodrome , was constructed on the island and this was attacked several times by Japanese planes. The World War II airbase on Horn Island

In 1979, the Australian Law Reform Commission released Privacy and the Census , a report detailing legislative privacy measures related to the census. One of the key elements under question was the inclusion of names and addresses in census data. It was found that excluding names reduced
5253-435: The ABS has destroyed census forms or other census-related personal information after the census data processing period, roughly 18 months after the census. Following a public consultation process before the 2016 census, it was found that Australians expected the ABS to hold their information for as long as there is a benefit to the community, and should be destroyed as soon as that need no longer exists. Following this process,

#17327901143475356-401: The ABS has revised the retention period to four years after census, instead of 18 months. Concurrently, the ABS also improved their anonymisation techniques and limits access to addresses and anonymised names to when only necessary. Since 2001, the ABS and National Archives of Australia have given respondents the option to have their complete census data, including name and address, stored in

There is archeological evidence that Canary Islanders would chew the roots of ferns for sustenance, a practice that wore heavily on their molars . These islanders would also grow barley and raised livestock such as goats . Many island nations have little land and
6077-682: The Origin of Species . The first evidence of humans colonizing islands probably occurred in the Paleolithic era, 100,000 to 200,000 years ago. Reaching the Indonesian islands of Flores and Timor would have required crossing distances of water of at least 29 km (18 mi). Some islands, such as Honshu , were probably connected to the mainland with a land bridge that allowed humans to colonize it before it became an island. The first people to colonize distant oceanic islands were

For example, the presence of freshwater fish on an island surrounded by ocean would indicate that it once was attached to a continent, since these fish cannot traverse the ocean on their own. Over the course of time, evolution and extinction changes the nature of animal life on a continental island, but only once it splits from the mainland. An example is that of the southern beech ,

Agriculture and trade also have introduced non-native life to islands. These processes result in an introduction of invasive species to ecosystems that are especially small and fragile. One example
7622-400: The ecological processes that take place on islands, with a focus on what factors effect the evolution , extinction , and richness of species. Scientists often study islands as an isolated model of how the process of natural selection takes place. Island ecology studies organisms on islands and their environment. It has yielded important insights for its parent field of ecology since
7725-430: The extensive epidemic of infectious diseases which occurred soon after many in those age groups were born". Rubella was not known to be a possible contributor. During World War II , the ophthalmologist Norman McAllister Gregg began to investigate the connection between birth defects and the infection of mothers early in their pregnancy. In 1951, prompted by Gregg's work, Australian statistician Oliver Lancaster examined
7828-528: The extent to which individuals associate with particular cultural or ethnic groups. Australia's first census was held in November 1828 in New South Wales , a British colony at the time. Previous government statistical reports had been taken from "musters" where white immigrants were brought together for counting. In 1828, the white population was 36,598: 20,870 settlers and 15,728 convicts. 23.8% of
7931-509: The first year of Federation, 1901, was again collected by each state separately. When planning for the 1901 census it was clear that federation was soon to occur, and a uniform census schedule was adopted. The first national census was developed by the Commonwealth Bureau of Census and Statistics. The census occurred at midnight between 2 and 3 April 1911. Tabulation was carried out almost entirely by hand; over 4 million cards were sorted and physically counted for each tabulation. Results from
8034-502: The habit of true warbler species) consumes spiders and insects that live on plants. Other examples of this phenomenon exist worldwide, including in Hawaii and Madagascar, and are not limited to island ecosystems. Species endemic to islands show a common evolutionary trajectory. Foster's rule (also known as the island rule), states that small mammals such as rodents evolve to become larger, known as island gigantism . One such example
8137-457: The islands as a naturalist on HMS Beagle in 1835, as part of a five-year circumnavigation of Earth. He wrote that "the different islands to a considerable extent are inhabited by a different set of beings". Through the study of the finches and other animals he realized that organisms survive by changing to adapt to their habitat. It would be over twenty years before he published his theories in On
8240-643: The largest landmass of a particular tectonic plate . Islands can occur in any body of water, including lakes , rivers , seas . Low-tide elevations , areas of land that are not above the surface during a high tide , are generally not considered islands. Islands that have been bridged or otherwise joined to a mainland with land reclamation are sometimes considered "de-islanded", but not in every case. The word island derives from Middle English iland , from Old English igland (from ig or ieg , similarly meaning 'island' when used independently, and -land carrying its contemporary meaning. Old English ieg
8343-404: The mainland, they had no need for boats. The motivation for island exploration has been the subject of research and debate. Some early historians previously argued that early island colonization was unintentional, perhaps by a raft being swept out to sea. Others compare the motivations of Polynesian and similar explorers with those of Christopher Columbus , the explorer who sailed westward over
8446-589: The majority of the local economy and built environment . These islands sometimes also require consistent foreign aid on top of tourism in order to ensure economic growth. This reliance can result in social inequality and environmental degradation . During tourism downturns, these economies struggle to make up the lost inflow of cash with other industries. Climate change threatens human development on islands due to sea level rise , more dangerous tropical cyclones , coral bleaching , and an increase in invasive species . For example, in 2017 Hurricane Maria caused
8549-497: The number of Aboriginal persons, both those of more than 50 percent Aboriginal descent and those of 50 percent or more non-Aboriginal descent, by obtaining figures from police and protectors of Aboriginal persons throughout the country. One of the significant findings of the 1921 census was the low rate of males to females in the 20–30 age group, showing the impact of World War I on the population. The 1921 census introduced automatic machine tabulation equipment, hired from England for
8652-426: The online census website shut down at about 7:30 pm AEST on the night it was to be completed. According to the ABS, throughout 9 August the census website received four denial-of-service attacks . At 7:30 pm, when the site was being heavily used, a software failure meant that the ABS was unable to keep blocking the denial-of-service attacks, leading to the failure of a router. As a result, the ABS decided to close down
8755-529: The past, some societies were found to have lost their seafaring ability over time, such as the case of the Canary Islands , which were occupied by an indigenous people since the island's first discovery in the first century until being conquered by the Spanish Empire in 1496. It has been hypothesized that since the inhabitants had little incentive for trade and had little to any contact with
8858-467: The population were born in the colony and 24.5% were women. There were 25,248 Protestants and 11,236 Catholics. Indigenous Australians were not counted. Of the 36,598 people, 638 were living in what is now Queensland . There were also 18,128 people in Tasmania . In the mid-19th century the colonial statisticians encouraged compatibility between the colonies in their respective censuses, and in 1881
8961-490: The same legal rights. 2011 Australian census The Census in Australia , officially the Census of Population and Housing , is the national census in Australia that occurs every five years. The census collects key demographic, social and economic data from all people in Australia on census night, including overseas visitors and residents of Australian external territories , only excluding foreign diplomats. The census
9064-789: The sea entirely. An example is the Hawaiian Islands , with the oldest island being 25 million years old, and the youngest, Hawaii , still being an active volcano . However, not all island chains are formed this way. Some may be formed all at once by fractures in the tectonic plates themselves, simultaneously creating multiple islands. One supporting piece of evidence is that of the Line Islands , which are all estimated to be 8 million years old, rather than being different ages. Other island chains form due to being separated from existing continents. The Japanese archipelago may have been separated from Eurasia due to seafloor spreading ,
9167-549: The study of islands is due to their unique cultures and natural environments that differ from mainland cultures. This is for a few reasons: First, the obvious political and geographic isolation from mainland cultures. Second, unique restraints on resources and ecology creating marine-focused cultures with a focus on fishing and sailing. Third, a lasting historical and political significance of islands. The Polynesian diet got most of its protein from fishing. Polynesians were known to fish close to shore, as well as in deep water. It
9270-450: The surface. When these coral islands encircle a central lagoon , the island is known as an atoll . The formation of reefs and islands related to those reefs is aided by the buildup of sediment in shallow patches of water. In some cases, tectonic movements lifting a reef out of the water by as little as 1 meter can cause sediment to accumulate and an island to form. Barrier islands are long, sandy bars that form along shorelines due to
9373-402: The system as a precaution. The ABS reported that no census data were compromised. The Australian Signals Directorate was assisting the ABS to bring the infrastructure back online more than 24 hours after the closure. The census website was restored at 2:30 pm on 11 August. On the same day, Prime Minister Malcolm Turnbull stated his displeasure over the event, which had "been a failure of
9476-524: The territories of Cocos (Keeling) Islands were included in the 2006 census, following the enactment of the Territories Law Reform Act 1992 . The 2006 census contained 60 questions, all of which were compulsory except those relating to religion and household census data retention. The census cost around A$ 300 million to conduct. For the first time, respondents were given the option of completing an online "eCensus" as opposed to
9579-438: The time of Charles Darwin . In biology, endemism is defined as the phenomenon where species or genus is only found in a certain geographical area. Islands isolate land organisms from others with water, and isolate aquatic organisms living on them with land. Island ecosystems have the highest rates of endemism globally. This means that islands contribute heavily to global biodiversity . Areas with high lives of biodiversity are
9682-535: The time that persons of 50 percent or more non-Aboriginal descent were not Aboriginal persons for the purposes of the Constitution. At the first Australian census in 1911 only those Aboriginal persons living near white settlements were enumerated, and the main population tables included only those of 50 percent or more non-Aboriginal descent. Details of Aboriginal persons of 50 percent or more non-Aboriginal descent were included in separate tables to Aboriginal persons of more than 50 percent Aboriginal descent. This practice
9785-527: The traditional paper-based version. By 17 August, more than 720,000 households had completed the census online. Across Australia, 8.4% of estimated dwellings lodged online. The highest percentage of internet lodgements was in the Australian Capital Territory with 14.8% of households using eCensus. This was a markedly different proportion of households than elsewhere in Australia, with the other states and territory ranging from 5.9% in
9888-428: The western end of the island. In the late 1980s, gold was mined again and Horn saw the rapid expansion of its population and building activity, as land on neighbouring Thursday Island became scarce. The Horn Island State School opened on 1 February 1993. It became a campus of Tagai State College on 1 January 2007. At the 2006 census , Horn Island had a population of 585 people. At the 2011 census , Horn Island had
9991-566: Was followed in all subsequent censuses up to 1966. Since 1967, the ABS has considered Torres Strait Islanders a separate Indigenous people. Prior to 1947, Torres Strait Islanders were regarded as Aboriginal and excluded when not of 50 percent or more non-Aboriginal descent. In 1947, Torres Strait Islanders were considered to be Polynesian and in 1954 and 1961 were considered to be Pacific Islanders . In 1966, Torres Strait Islanders were again regarded as Aboriginal and excluded when not of 50 percent or more non-Aboriginal descent. Ancestry data
10094-406: Was held on 7 August. There were 18,769,420 people counted in Australia. Of these, 410,003 people identified as Indigenous Australians. There were 203,101 overseas visitors. The 2006 census was conducted on the night of 8 August. There were 19,855,288 people counted in Australia. Of those, 455,031 people identified as Indigenous Australians. There were 206,358 overseas visitors. For the first time,
10197-533: Was included in the 1986 census. It was found when the data was evaluated that people who filled in the census were not sure what the question meant and there were inconsistent results, particularly for those people whose families had been in Australia for many generations. There were no ancestry related questions in 1991 or 1996 . For 2001 it was decided that development of Government policies did need information about people who were either born overseas, or whose parents were born overseas. The questions were to mark
10300-616: Was part of South Australia and had 3,451 white people plus 6,346 Aboriginals in settled districts. Including the Northern Territory, South Australia had a total counted population of 286,211 people. The reported population of Western Australia did not include Aboriginal persons of more than 50 percent Aboriginal descent. The population of greater Melbourne was 282,947 and of Sydney was 224,939. In 1901, there were 3,773,801 people (1,977,928 males and 1,795,873 females) counted in Australia. Prior to federation , each colony had been responsible for its own census collection. The census held during
10403-500: Was processed. There were 13,548,450 people counted. Scanned data of the 1981 Census is available on the ABS website. The 1986 Census was held on 30 June 1986. Scanned data of the 1986 Census is available on the ABS website. The 1991 census was held on 6 August 1991. The 1996 census was held on 6 August. There were 16,892,423 people counted in Australia. Of these, 342,864 people identified themselves as Indigenous Australians. There were 139,594 overseas visitors. The 2001 census
10506-470: Was reported that Rapa Nui people were known to fish as far as 500 km (310 mi) from shore at coral reefs. Spear , line , and net fishing were all used, to catch tuna as well as sharks and stingrays . Island cultures also cultivate native and non-native crops. Polynesians grew the native yam , taro , breadfruit , banana , coconut and other fruits and vegetables. Different island climates made different resources more important, such as
10609-559: Was widely believed at the time of the referendum, and is still often said, that section 127 meant that Aboriginal persons were not counted in Commonwealth censuses before 1967. In fact section 127 related to calculating the population of the states and territories for the purpose of allocating seats in Parliament and per capita Commonwealth grants. Its purpose was to prevent Queensland and Western Australia using their large Aboriginal populations to gain extra seats or extra funds. Thus
