Comedian Dave Thornton leads 4 celeb teams across the Outback, tackling wild challenges for $300k in EV prizes. From oyster-eating in Ceduna to 'Queen of the Desert' antics, rivalry and laughs ensue.

Teams road trip to Streaky Bay, where Lehmo teaches Dilruk to drive. In Wuddina, costumes delight kids, winning Dil & Lehmo. Pia steals points in Duck Ponds & all face a shark dive at Neptune Island.

After a quick break the roadtrippers take on local bowlers at Arno Bay before Nikki & Gyton race a speedy camel. Later, they take on an epic selfie drop in the Flinders Ranges as Pia faces her fear.

The teams hit the snow, with one legend pushed to exhaustion. A close surf race brings victory, and the winners gift fans new cars in Sydney.
