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.
Constitutional history of Australia
During the 19th century, separate British colonies were formed in Australia. In 1825, Tasmania, named Van Diemen's Land, was proclaimed a separate colony from the colony of New South Wales. The Swan River Colony of Western Australia was established in 1832, separately from that of New South Wales, effectively taking over by Britain of the remainder of the Australian continent. Following the Treaty of Waitangi, William Hobson declared British sovereignty over New Zealand in 1840 and was part of the colony of New South Wales. In 1841, it was separated from the colony of New South Wales to form the new Colony of New Zealand. South Australia was formed in 1836 separately of the colony of New South Wales, and Victoria in 1851 and Queensland in 1859 both from the colony of New South Wales. By Letters Patent on 6 June 1859, Queen Victoria gave her approval to the separation of the colony of Queensland from New South Wales. On the same day an Order-in-Council gave Queensland its own Constitution. Queensland became a self-governing colony with its own Governor, a nominated Legislative Council and an elected Legislative Assembly. South Australia was founded as a "free province"—it was never a penal colony. Victoria and Western Australia were also founded "free", but later accepted transported convicts. A campaign by the settlers of New South Wales led to the end of convict transportation to that colony; the last convict ship arrived in 1848.
