Black Diamond Lake

The viral popularity of a picturesque isolated swimming hole on social media has led to a tourism boom at a West Australian lake that is inside an abandoned mine.

You might have seen images of swimmers floating peacefully on an aqua lake so bright in colour, it looks digitally enhanced. Don’t forget to bring your inflatable floaty toys!

Black Diamond Lake is an abandoned mine site south of Perth. The lake was filled with water after it was decommissioned in the 1950s and has been a popular swimming hole for locals ever since.

The town of Collie is only five kilometres southeast of the lake, so make sure to drop in for a bite to eat, do a bit of shopping and check out the visitor information centre to find out what else you can get up to in Collie.

There have also been water quality issues and signage has been erected to warn swimmers when dangerous levels of bacteria are present in the water. So make sure to read these signs before you head on in.
