Cumbebin Swamp Nature Reserve is an important part of Country to the Bundjalung of Byron Bay (Arakwal) people and is subject to an Indigenous Land Use Agreement (ILUA), signed in 2008, which more than doubled the size of Cumbebin Swamp Nature Reserve from its original 40 hectares. Under the ILUA the reserve will be jointly managed with the Bundjalung of Byron Bay (Arakwal) people through a management committee.
Cumbebin Swamp Nature Reserve also conserves wetlands of state significance, sensitive coastal dunes, coastal swamp forests and riparian areas. It contains three endangered ecological communities, which provide habitat for a wide range of native animals including threatened species.
