Outback Opal Hunters 14-9

The world's toughest treasure hunters push their bodies and bank accounts to the limit on a quest to strike it rich, hunting the legendary Queen of Gems - Opal.

Right on the Mark. When Mark is hospitalised after a mining accident, Paul and John must work overtime on two separate claims to scrape together enough opal to survive the week.

The Bushmen accidentally unleash a potentially fatal threat to the team. Slim Pickings consult a historian who helps them search for another source of old timers paydirt.
