Australian sea lion range

The Australian sea lion (Neophoca cinerea) also known as the Australian sea-lion or Australian sealion, is a species of sea lion that breeds only on the south and west coasts of Australia. It is monotypic in the genus Neophoca.

Phylogeny[link]

The Australian sea lion is a pinniped most closely related to other species of sea lion and fur seal in the family Otariidae.

Breeding behaviour[link]

The breeding cycle of the Australian sea lion is unusual within the pinniped family. It is an 18 month cycle and is not synchronised between colonies. The duration of the breeding season can range from 5 to 7 months and has been recorded for up to 9 months at Seal Bay on Kangaroo Island.

Bulls do not have fixed territories during the breeding season. The males fight other males from a very young age to establish their individual positions in the male hierarchy and during the breeding season, dominant males will guard females for the right to breed with her when she comes into oestrus. A female comes into season for about 24 hours within 7 to 10 days after she has given birth to her new pup. She will only look after the new pup and generally fights off the previous season's pup if it attempts to continue to suckle from her.

Male Australian sea lions are also known to kill young as an act of defence of territory.

Population status and protection measures[link]

There are approximately 14,730 Australian sea lions^[2] following the introduction of the Australian National Parks and Wildlife Act of 1972 which prohibited a harvest that began in earnest as soon as Europeans colonised the continent.

Australian people, or simply Australians, are the citizens of Australia. Australia is a multi-ethnic nation, and therefore the term "Australian" is not a racial identifier. Aside from the Indigenous Australian population, nearly all Australians or their ancestors immigrated within the past 230 years. Colloquial names used to refer to Australians include Aussies, and Antipodeans.^[3][4]

The mainstream Australian culture (occasionally defined as the Anglo-Celtic culture), is a Western culture largely derived from the traditions of Western European migrants beginning with the early settlers from England, Scotland, and Ireland. The populations of Sydney, Melbourne and the other major cities are different from the demographics of rural Australia as a result of the differing migration patterns.

Australian people can refer to:

• The citizens of Australia, as defined by Australian nationality law
• People whose ancestors lived in Australia

Indigenous Australians[link]

The earliest accepted timeline for the first arrivals of indigenous Australians to the continent of Australia places this human migration to at least 40,000 years ago most probably from the islands of Indonesia and Papua New Guinea.^[5]

These first inhabitants of Australia were originally hunter-gatherer peoples, who over the course of many succeeding generations diversified widely throughout the continent and its nearby islands. Although their technical culture remained static—depending on wood, bone, and stone tools and weapons—their spiritual and social life was highly complex. Most spoke several languages, and confederacies sometimes linked widely scattered tribal groups. Aboriginal population density ranged from one person per square mile along the coasts to one person per 35 square miles (91 km²) in the arid interior. Food procurement was usually a matter for the nuclear family, requiring an estimated 3 days of work per week. There was little large game, and outside of some communities in the more fertile south-east, they had no agriculture.

Australia may have been sighted by Portuguese sailors in 1701, and Dutch navigators landed on the forbidding coast of modern Western Australia several times during the 17th century. Captain James Cook claimed the east coast for Great Britain in 1770, the west coast was later settled by Britain also. At that time, the indigenous population was estimated to have been between 315,000 and 750,000,^[6] divided into as many as 500 tribes^{[citation needed]} speaking many different languages. In the 2006 Census, 407,700 respondents declared they were Aboriginal, 29,512 declared they were Torres Strait Islander, and a further 17,811 declared they were both Aboriginal and Torres Strait Islanders.^[7] After adjustments for undercount, the indigenous population as of end June 2006 was estimated to be 517,200, representing about 2.5% of the population.^[6]

Since the end of World War II, efforts have been made both by the government and by the public to be more responsive to Aboriginal rights and needs. Today, many tribal Aborigines lead a settled traditional life in remote areas of northern, central, and western Australia. In the south, where most Aborigines are of mixed descent, most live in the cities.

Australian diaspora[link]

There is an estimated 1 million Australians (approximately 5% of the population) residing outside Australia. Hundreds of thousands of young Australians traditionally spend time living in Europe, but most return to Australia. The Trans-Tasman Travel Arrangement facilitates open migration to and from New Zealand. Key factors affecting the Australian Diaspora are rise of a global labour market, more accessible and economical international transport, and increasingly sophisticated communication technologies along with a growing interest in broader global community.

Population[link]

The current Australian population is estimated at 23,203,000 (26 June 2012).^[8] This does not include an estimated 1 million Australians living overseas (see above), but it includes the estimated 24% of Australians born overseas (in various nations, but predominantly the United Kingdom, New Zealand, Italy, China, Vietnam, India, the Philippines, and Greece).^[9]

Historical[link]

The data in the table is sourced from the Australian Bureau of Statistics^[10][11] Note that population estimates in the table below do not include the Aboriginal population before 1961. Estimates of Aboriginal population prior to European settlement range from 300,000 to one million, with archaeological finds indicating a sustainable population of around 750,000.^[12]

Ancestry[link]

For generations, the vast majority of both colonial-era settlers and post-Federation immigrants came from the United Kingdom and Ireland, although the gold rushes also drew migrants from other countries. Since the end of World War II, Australia's population more than doubled, spurred by large-scale European immigration during the immediate post-war decades. At this time, the White Australia Policy discouraged non-European immigration.

Abolition of the White Australia Policy in the mid-1970s led to a significant increase in non-European immigration, mostly from Asia and the Middle East. About 90% of Australia's population is of European descent. Over 8% of the population is of Asian descent (predominantly Chinese, Vietnamese, Filipino and Indian).^[13] The total indigenous population is estimated to be about 520,000 individuals, including people of mixed descent.^[6] The population of Queensland also includes descendants of South Sea Islanders brought over for indentured servitude in the 19th century.

In the 2006 Australian Census residents were asked to describe their ancestry, in which up to two could be nominated. Proportionate to the Australian resident population, the most commonly nominated ancestries were:^[13]

At the 2006 Census 455,026 people (or 2.3% of the total Australian population) reported they were of Aboriginal and/or Torres Strait Islander origin.^[7]

Languages[link]

English, a West Germanic language, is the de facto national language of Australia and is spoken by the majority of the population, regardless of other languages spoken. Most Australians speak Australian English, however Australian Aboriginal English and Torres Strait English, along with various creoles and pidgins, are spoken by some Indigenous Australians. Australia is home to a great number of unique but endangered Indigenous Australian languages, as well as Australian Aboriginal sign languages. Australia's hearing-impaired community primarily uses Auslan, a member of the BANZSL language family.

The diverse backgrounds of Australians lead to a great number of community languages being spoken:

Religion[link]

Australians have various religions and spiritual beliefs. The Australian Bureau of Statistics gathers information on religious belief in the national census.^[14] As in many Western countries, the level of active participation in church worship is lower than would be indicated by the proportion of the population identifying themselves as Christian; weekly attendance at church services is about 1.5 million, or about 7.5% of the population.^[15]

Nationality[link]

Australians share Australian nationality, which is governed by Australian nationality law. Since there is no national identification card, commonly accepted proofs of Australian citizenship are the Australian passport, an Australian birth certificate (prior to 1986, when jus soli was abolished), or an Australian citizenship certificate. Australia permits dual citizenship with no restriction, but a more restricted qualification is imposed on people wishing to enter Parliament (see Sue v Hill).
