Evidence of Aboriginal occupation at Wilsons Promontory dates back at least 6,500 years and the park is highly significant to the Gunai/Kurnai and the Boonerwrung Clans who call it Yiruk and Warnoon respectively.
The first European to see the promontory was George Bass in January 1798. He initially referred to it as "Furneaux's Land" in his diary, believing it to be what Captain Furneaux had previously seen. But on returning to Port Jackson and consulting Matthew Flinders he was convinced that the location was so different it could not be that land. Bass and Flinders recommended the name Wilsons Promontory to Governor Hunter, honouring Flinders's friend from LondonThomas Wilson. Little is known of Wilson except that he was a merchant engaged in trade with Australia.
