Collie Coal Mines

Collie is a small mining town set in the middle of forests two hours South East of Perth.
The area was established as a timber milling town in the mid 1800s but after massive coal deposits were discovered in 1883, the town became the state’s energy capital. Collie remains prosperous as the major power stations supplying Perth’s electricity are situated here, above deep, open cut coal mines.

A number of disused underground coal mines dating from the early 1900s have flooded and are now being explored by Perth based cave divers using both open and closed circuit equipment
