The series begins in the iconic city of Sydney, where Brad's fear of heights is put to the test with a terrifying aerobatic flight and a trip on an extreme cable car.

The boys are now in the Aussie countryside and learn how to shear sheep before joining a local community whose fundraiser involves pulling a gigantic truck.

The boys have hit the Gold Coast, where Barney has sun, sea and some serious action planned - including setting his old man on fire in an epic stunt.

Bradley and Barney arrive in Brisbane, where they swap the RV for electric scooters to explore the city.

The duo head to the outback, where they help farmers muster their cattle.

The final leg of their journey takes them to the gateway of the Great Barrier Reef.
