The park features the southernmost subtropical rainforest in New South Wales.

[1] In 2001, as part of the Southern Comprehensive Regional Forest Agreement and at the request of Yuin people, Gulaga National Park was created out of the existing Wallaga Lake National Park, Goura Nature Reserve, and Mt Dromedary Flora Reserve.

[5] On 6 May 2006 the freehold titles to Gulaga and Biamanga National Parks were handed back to the Yuin people, the traditional owners of the land, by the New South Wales Government, represented by then New South Wales Environment Minister Bob Debus.

Freehold title of Gulaga National Park is held in trust by land councils for the Aboriginal owners by Merrimans and Wagonga Local Aboriginal Lands Councils, while that of Biamanga will be held in trust by Merrimans and Bega Local Aboriginal Lands Councils.
