Wallaga Lake National Park is a former national park in New South Wales, 296 km southwest of Sydney, Australia. It now forms part of a greater Gulaga National Park. In May 2006, ownership to this former National Park, plus the rest of the Gulaga National Park, was restored to the area's original owners, in whom legal tenure was vested (in trust) as part of an agreement signed by then New South Wales Environment Minister Bob Debus and representatives for the Yuin people
