Outback Opal Hunters 7-4

The Bushmen battle to break through into an abandoned mine. The Young Guns face equipment failure 800km from home.

In outback NSW, the worst storm in 20 years devastates the Bushmen's and Chris Cheal's mine, while in Coober Pedy, a new team the Blacklighters need opal to re-establish.

A mountain of mine-waste rains down on the Blacklighters, threatening their operation. The Mooka boys head for a abandoned mineshaft believed to be full of cut opal.
