What is the capital of Australia?

Short answer

Canberra, in the Australian Capital Territory. It is not Sydney and not Melbourne — it was purpose-built as a compromise after both cities claimed the title at federation. The site was chosen in 1908, the city was named in 1913, and Parliament moved there in 1927.

When the six colonies federated in 1901, Sydney and Melbourne both expected to become the national capital and neither would accept the other. Section 125 of the Constitution resolved it by requiring the capital to be in New South Wales but at least 100 miles from Sydney, with Melbourne serving as the seat of government in the meantime.

The site was selected in 1908 and land was transferred from New South Wales to form the Australian Capital Territory. An international design competition was won by the American architects Walter Burley Griffin and Marion Mahony Griffin, whose plan shaped the city's geometric layout of circles, axes and the artificial Lake Burley Griffin.

The city was officially named Canberra on 12 March 1913. Parliament sat in Melbourne until 1927, when it moved to the Provisional Parliament House — now Old Parliament House. The current Parliament House opened in 1988.

Canberra is Australia's eighth-largest city with roughly 475,000 residents, and it is the largest inland city. It has the highest median income and the highest share of degree-holders of any Australian jurisdiction, both consequences of a public-service economy.

It is also home to the High Court, the National Gallery, the National Library, the Australian War Memorial and every foreign embassy in Australia.
