It lies several kilometres south of the Macintyre River, which forms the border between Queensland (to the north) and New South Wales, and is just north of the Mungindi - Goondiwindi road. Its outflow, which connects to the river, is named Boobera Watercourse.
The lagoon is 7 kilometres in length and supports a wide variety of aquatic and bird life.

The lagoon was particularly significant to the Bigambul and Kamilaroi people, who held the third stage of their joint male initiation ceremonies at this site.
