History of Sydney
With the inauguration of the Commonwealth of Australia on 1 January 1901, Sydney ceased to be a colonial capital and became the capital of the Australian state of New South Wales. With industrialisation, Sydney expanded rapidly, and by the early 20th century it had a population well in excess of one million.
Capital districts and territories
The Australian Capital Territory (ACT) is one of two self-governing internal territories of the Australian federation, the other being the Northern Territory (NT). Created in 1911, the ACT was originally called the Federal Capital Territory, the current name being acquired in 1938. The ACT was constituted specifically to house the seat of government, the goal being to avoid situating the new nation's capital Canberra in either New South Wales or Victoria, the two most populous states. The ACT is an enclave of New South Wales.
