The theme of the show is to demonstrate how various couples deal with the challenges and pitfalls of attempting a long-distance hitchhike to a strange city, together with all the difficulties presented by trying to communicate in a language they don’t understand.

Tension was added by including couples who had broken up “in real life”, but were willing to work together for the sake of winning the race.

Before arriving at the Ridge, the competitors were to hitchhike from Coonamble.

The group spent Tuesday and Wednesday filming at the Bore Baths, Walk in Mine, and the old church at the Four Mile before moving onto Bourke.

In somewhat similar fashion to The Amazing Race, couples that come in last at various checkpoints along the way are eliminated.
