Australia is a rapidly growing country. Its growth is fuelled by immigration.


At the start of 2016, Australia’s population was estimated to be 23,984,200. Australia today is the 53rd most populous country in the world.

The population has grown by almost 2.5 million people in the five years since the last census, held in 2011, recorded an official population of 21,507,717.

Nominal GDP per capita in 2014 was, according to the IMF, $51,642, ranking Australia 7th in the world.

Australian GDP growth over the past few years has been in the 2-4% range – outperforming most European economies, but lagging slightly behind US growth.

History of Australia


Humans first arrived on the Australian continent nearly 50,000 years ago. In 1788, when the first colonists landed, their population was estimated at between 750,000 and 1 million. They had a predominantly hunter-gatherer lifestyle. No written records exist – their history and culture was passed down orally.

Willem Janszoon, a Dutch sailor, was the first European person to land in Australia, on 26 February 1606. Although the Dutch named this new territory New Holland, they did not settle here.

Instead, it was the English who colonised Australia. Captain James Cook mapped the East Cost of Australia in 1770 and claimed the territory for Great Britain. Captain Arthur Phillip led the first colony – a penal colony that landed near present day Sydney on 26 January 1788.

Britain gradually expanded its penal colonies over the next 50-75 years – driven partly by a need to exile its criminals somewhere far away and partly by a desire to secure a territory that could compensate for its loss of North America in 1783. Gradually, as the penal colonies became established, civilian colonists followed. Over the next fifty years they gradually took on responsibility for their own governance.

The Commonwealth of Australia, a dominion of the British Empire, was established on 1 January 1901. The Commonwealth brought together each of the separate colonies into a single, self-governing, federation.

Australia was rapidly industrialising and growing in economic strength. By the time of the first world war, it was able to send more than 400,000 men to join the fighting in Europe – more than 60,000 of whom were killed in the conflict. Gallipoli, in present day Turkey, is regarded as the Australian military’s first major battle. Australia’s army, navy and air force also played a major part in the Second World War, fighting against Nazi Germany in Europe and the Japanese Empire in Asia.

Growing in confidence, Australia gradually reduced its formal constitutional links with Britain – most were severed in the Statue of Westminster in 1931; the final ties were cut by the Australia Act of 1986.
