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.
History of New South Wales
The Sydney International Exhibition of 1879 showcased the colonial capital to the world. Some exhibits from this event were kept to constitute the original collection of the new "Technological, Industrial and Sanitary Museum of New South Wales" (today's Powerhouse Museum).
