Outback Opal Hunters

The Bushmen, Rod Manning and Les Walsh, alongside new recruit Sam Mehan, put their lives on the line in the most dangerous mine they have ever worked; incompetence with a new bulldozer lands The Blacklighters in hot water with Mark's wife.

Cody's eagerness to prove himself becomes a liability as he gets trapped down a mine shaft; just as they're making progress at their crumbling, fault-riddled mine, The Bushmen are blindsided by a digger failure.

The Misfits struggle to find an opal king stone in time to fulfill a bespoke pendant order for an interstate buyer; Mark Bressan and Chris Cheal battle to fix their downed excavator as encroaching wet weather attracts ratters to their exposed mine.

Slim Pickings' efforts to mine their claim are derailed by a slipped excavator track and busted wash plant motor belt; the Blacklighters face off against big rain and even bigger egos as they scrounge for any last opal at their Land of Promise claim.

Sam smashes valuable opal with a jackhammer in the Bushmen's mine; Rod and Les make a wager that will force the loser to wear one of Sam's pink shirts in public.

The Cheals' dreams of expanding their business, Opal Empire, are crushed by the reality of juggling two mines; the Misfits are reunited after Issy and Joe's return; Slim Pickings' Lee Hobden takes a gamble on mystery opal dirt.

Chris suffers a spider bite, forcing Oscar and Luca to take up the mining mantle; Lee from Slim Pickings battles dangerous shaft-riddled ground on a quad bike; a thirty-thousand-dollar mechanical failure brings Dan and Renee's enterprise to a halt.

The Blacklighters get hit with a double dose of disaster, busting their loader's brakes and the excavator's hydraulic arm; the Bushmen get blindsided by a government decision to shut down thousands of opal claims across New South Wales.
