In the fifth episode of Aussie Animal Island, Reba, one of the eight female devils, has finally got the hang of finding food. Now she must find a mate to breed a new generation of disease-free devils.

As breeding season draws near, the scientists set traps around the island to capture and examine each of the devils to ensure they are healthy and ready to mate.

But it's not just the devils who are getting ready to breed as the male wombats and forester kangaroos put on rare displays of masculine aggression to conquer their competitors and court their mates.
