The Burke and Wills expedition was an Australian exploration expedition in 1860–61 led by Robert O'Hara Burke and William John Wills of 19 men with the objective of crossing Australia from Melbourne in the south, to the Gulf of Carpentaria in the north, a distance of around 3,250 kilometres (approximately 2,000 miles). At that time most of the inland of Australia had not been explored by non-Indigenous people and was largely unknown to the European settlers.
The expedition left Melbourne in winter. Bad weather, poor roads and broken-down wagons meant they made slow progress at first. After dividing the party at Menindee on the Darling River Burke made good progress, reaching Cooper Creek at the beginning of summer. The expedition established a depot camp at the Cooper, and Burke, Wills and two other men pushed on to the north coast (although swampland stopped them from reaching the northern coastline).
The return journey was plagued by delays and monsoon rains, and when they reached the depot at Cooper Creek, they found it had been abandoned just hours earlier. Burke and Wills died on or about 30 June 1861. Several relief expeditions were sent out, all contributing new geographical findings. All together, seven men lost their lives, and only one man, the Irish soldier John King, crossed the continent with the expedition and returned alive to Melbourne.
Gold was discovered in Victoria in 1851 and the subsequent gold rush led to a huge influx of migrants, with the local population increasing from 29,000 in 1851 to 139,916 in 1861 (Sydney had 93,686 at the time). The colony became very wealthy and Melbourne grew rapidly to become Australia's largest city and the second largest city of the British Empire. The boom lasted forty years and ushered in the era known as "marvellous Melbourne". The influx of educated gold seekers from England, Ireland and Germany led to rapid growth of schools, churches, learned societies, libraries and art galleries. The University of Melbourne was founded in 1855 and the State Library of Victoria in 1856. The Philosophical Institute of Victoria was founded in 1854 and became the Royal Society of Victoria after receiving a Royal Charter in 1859.
