Mimbi is a small community in the heart of Gooniyandi Country close to the Mimbi Caves. It is about 90km east of Fitzroy CrossingThe Gooniyandi are a small group and less than a hundred people now speak the language in the Fitzroy Crossing area.

The Mimbi caves are important to the Gooniyandi as a spirit and trading centre and probably occupied for more than 40,000 years until European settlement.This is one of the oldest, dated, human occupation sites in Australia. In the early 1980's a small group of the Gooliyandi people decided to return to the the caves area from where they worked on the surrounding cattle stations and a small scale tourism project started.

The limestone caves are part of a reef that formed underwater about 350 million years ago. They contain permanent pools of water as well as many fossils. It is one of the most significant fossil sites in the Southern Hemisphere. Ancestors of the Gooniyandi also painted pictures in the cave walls depicting their hunter gather life.
