After being granted self-governance, Victoria (in 1851) and New South Wales (in 1856), saw a steady economic growth as result of the discovery and exploitation of gold reserves. This growth during the 1850s and 1860s led to rivalry between their respective capitals Melbourne and Sydney. In the 1870s the focus turned to the outside world and proposals were made for organising an exhibition modelled on the great exhibitions of Europe, with an aim to promote commerce and industry, along with art, science and education.
