Leg 1 (South Korea). Hosted by television's loveable loose-cannon Beau Ryan, 22 Aussie hopefuls will tackle trains, planes and camels as they ping-pong across the world in pursuit of the $250,000 cash prize.

Leg 2 (South Korea). Teams will need to choose their challenges wisely when an obstacle course or a skill testing drone flight are on the table. The last team to arrive at the Pitstop may be eliminated.

Leg 3 (South Korea → Vietnam). Teams must head to a local puppet theatre to get their clues for the next destination before having to undertake an eating challenge which is not for the faint hearted.

Leg 4 (Vietnam). The contestants find themselves battling as much with the heat as with each other. It's a mad dash to the end as the teams do all they can to avoid being eliminated from the race.

Leg 5 (Vietnam → Mongolia). The race is well and truly underway as the remaining teams land in Mongolia. All hell breaks lose as the teams try to milk goats, herd sheep and ride camels across the sand dunes.

Leg 6 (Mongolia). The teams IKEA skills are put to the test as they must deliver and assemble goods to a local market. Unfortunately, for one team, it's the end of the race and the end of their shot at $250,000.

Leg 8 (Zambia → Zimbabwe). Teams race through the challenges, but for those afraid of heights, swinging over a gorge isn't their ideal good time. Will they push themselves or will their hesitation cost them the race?

Leg 9 (Zimbabwe → Malawi). Five teams remain, as they make their way through Malawi and get closer to the winning prize of $250,000. If you can shell peanuts, mould bricks or sew shirts, then this is your leg of the race!

Leg 10 (Malawi). Would you rather spend the day doing laundry by hand or sorting through different species of fish? And what if that decision could cost you $250,000?

Leg 11 (Malawi → Thailand). The final four teams make their way to Thailand. Teams are faced with their toughest eating challenge yet, with every contestant having to take part in order to get their next clue.

Leg 12 (Thailand → Australia).
