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.
Australian Capital Territory (Self-Government) Act 1988
The territory presently called the Australian Capital Territory was transferred to the Commonwealth by the state of New South Wales as the "Federal Capital Territory" on 1911, to be the seat of the federal government. The planning and construction of Canberra followed, with the Parliament of Australia moving there in 1927.
