The first publicised discovery of gold in the region was by Thomas Hiscock on 2 August 1851, in Buninyong to the south. The find brought other prospectors to the area and on 19 August 1851, more gold was found at Poverty Point. Within days, a gold rush began, bringing thousands of prospectors to the Yarrowee Valley, which became known as the Ballarat diggings. Yields were particularly high, with the first prospectors in the area extracting between half an ounce (which was more than the average wage of the time) and up to five ounces of alluvial gold per day. As news of the Victorian gold rush reached the world, Ballarat gained an international reputation as a particularly rich goldfield. As a result, a huge influx of immigrants occurred, including many from Ireland and China, gathering in a collection of prospecting shanty towns around the creeks and hills. Within a few months, numerous alluvial runs were established, several deep mining leads began, and the population had swelled to over 1,000 people.
