In the latter part of the nineteenth century, discoveries of gold at a number of locations in Western Australia caused large influxes of prospectors from overseas and interstate, and classic gold rushes. Significant finds included:
A small rush at Nundamurrah Pool, on the Greenough River, near Mullewa, east of Geraldton occurred in August 1893.
The Kalgoorlie event in particular, following the June 1893 discovery of alluvial gold at the base of Mount Charlotte by Irish prospectors Paddy Hannan, Tom Flanagan and Dan O'Shea, saw a massive population increase and ultimately, brought great wealth to the state. Capital works, including roads and railways and in 1896, construction of the ambitious Goldfields Water Supply Scheme, came about on the back of the gold rushes.
The population in Western Australia in 1891 was 49,782. By 1895 it had doubled to 100,515, and by 1901 was 184,124.
The far-reaching nature of the mining excitement drew men from all over the world in 1895. People immigrated from Africa and America, Great Britain and Europe, China and India, New Zealand and the South Sea Islands, and from mining centres in Queensland, New South Wales, Victoria, Tasmania, and South Australia. There was a total of 29,523 immigrants (24,173 males and 5,350 females) in 1895, while the emigration amounted to 11,129, leaving Western Australia the gainer by 18,394 persons. The population of the colony in 1895 was 101,235, made up of 69,727 males and 31,508 females. The immigration in December was greater than that of any preceding month, and totalled 4,540. Most of these people came from the Eastern colonies, which were still greatly depressed.
These previously unexplored eastern districts were hot and barren and had limited natural water supplies or pre-existing infrastructure to support sudden influxes of people. As a result, all supplies had to be carted, either from Perth or Esperance. Carted water was sold for up to 5 shillings per gallon.
