Wallaga Lake National Park is a former national
park in New South Wales, 296 km southwest
of Sydney, Australia. Wallaga Lake now forms part
of a greater Gulaga National Park.
In the 2011 Australian census the population of
Wallaga Lake was 526 when there were 253
Females and 273 Males living there. The median
age for people living in Wallaga Lake was 52.

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
