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.
Cardiff, New South Wales
For a short period in the 1880s Lymington became the popular name for the whole Cardiff area, supplanting Winding Creek, however it fell foul of the postal authorities, because of its similarity to another, established locality name. There were a number of Welsh settlers living in the area, and on the suggestion of one of them, James Edwards, the name Cardiff was chosen after the capital of Wales. It was officially adopted in 1889.
