1851 in Australia was a watershed year. It saw the start of the Australian gold rushes with significant gold discoveries in both New South Wales (near Bathurst) in February and Victoria in July.^[1] As a result of the Gold Rushes, the European population of Victoria increased from 97,489 in 1851 to 538,628 in 1861 and the population of NSW increased from 197,265 in 1851 to 350,860 in 1861.^[2] Victoria became a self-governing colony. Sentiment in the eastern Australian colonies moved decisively against penal transportation leading to the end of transportation to Tasmania in 1853. Melbourne's major suburb/satellite city in the Dandenong Ranges, Belgrave was first settled, making it the oldest town in the Dandenong Ranges.
