This year celebrates a decade of dirt for All 4 Adventure, and the boys are headed back to where it all began… The Kimberley. Jase and Simon hit the track at Ivanhoe Crossing, but they notice they're being tailed by another vehicle. As they pull up to the Hillgrove Lockup boab tree, they realise it's their old mate Jesse who is coming along for the adventure. They head down the unmaintained Karunji Track at their own risk, and it's not long before they come across some spongey areas, and Jase gets bogged with the big boat trailer. They have to make up their own route when the track ends in a washed out area. And the second half of the track just keeps getting worse with creek crossing after creek crossing. They finally get to wash off the dust when they reach the Pentacost River on the Gibb River Road.

The boys start out at Honeymoon Bay where the wind is causing rough seas, but they've got a mission to find a bit of history. First up is an old RADAR station on an Sir Graham Moore island in Napier Bay. And later Jase has an old plane wreck that he wants to show Jesse which brings them further into Vansittart Bay. After a beach launch, they set off to find this old needle in a haystack. But poor crook Jesse's used to calm creek waters and not the open sea. But there's always time to flick a line along the way, and they manage to find some mangrove jack, mackerel, bluebone and trevally on the bite this journey. And Simon does his version of a cook-up. But Jase shows him how it's really done later with a tasty dessert for the local kids who show them how they make spears. The kids make it look easy!
