Ep 20. One Plus One Equals Three

As Grawin burns and camps are destroyed in cataclysmic fires, the Bushmen, Rod, Sam and Ben must use their last dig of the season to secure enough opal for Les' long-awaited retirement. The Blacklighters limp into their final week still without team leader Mark and Paul takes the lead in an opal sale, but some erroneous mental arithmetic ends up costing the boys thousands of dollars. The Misfits defy Opal Joe's orders and divide forces until Cody almost meets his demise down a 10-metre mine shaft. Angel unearths crystal opal in Andamooka's biggest open cut mine and hopes to trade it for a brand-new house before season end.
