Jase and Simon return in the 9th series of All 4 Adventure: Tackling the Territory. Starting at the southern Queensland border, they set out on an expedition to locate a lost 130-year-old marker along the Northern Territory border. On their way from the Simpson Desert to the Gulf of Carpentaria, they visit the centre of Australia, meet colourful locals, assist in a wild croc relocation, and are taken to rarely-visited sites at Groote Eylandt where stunning Aboriginal artwork sheds new light on the history of the region. There are plenty of challenges on and off the tracks, and the recovery gear is pushed to the limit. With all-new trucks, a new caravan, and a military-grade Unimog for extreme bush bashing, this is a whole new take on the Northern Territory like you’ve never seen before!
