Big Badja River

BW

The Big Badja River is a small river in the southeast of the Australian state of New South Wales.

It rises north-east of Badja (consisting of the districts of Little and Big Badja Badja ) on the western edge of the Deua National Park on the Great Dividing Range. From there, the Big Badja River flows to the southwest and flows into the Numeralla Numeralla River.

The swampy headwaters of the river and its tributary the Peppers Creek forms the Badja Swamps Nature Reserve, a state nature reserve below the Big Hill Badja within the boundaries of Deua National Park.
