Chief refuge value

The area contains a variety of environments undisturbed by feral animals. It is potentially one of the few remaining relatively pristine watercourses in central Australia.

General description

The Hay River is a linear riverine system coursing for 150 km through the north of the Simpson Desert. It supports a dense and varied shrub and woodland vegetation which is apparently free of exotic wildlife. Associated with the River is Lake Caroline, an ephemeral wetland of possible significance to waterbirds1.
