Aboriginal Land Council

Aboriginal land in this area is administered by the Karuah Local Aboriginal Land Council.

Local Aboriginal Land Councils are statutory bodies under the Aboriginal Land Rights Act 1983, responsible for land claims and land management for their members. Their boundaries are administrative and are not a statement of whose Country this is. NSW does not publish a register of Aboriginal parties by area — they are registered for each project.
