Alf and Camille are preparing for a trip to Australia to meet her rich brother, in the hope that he'll lend them money to buy their house cheap off the council once married. Alf, ever the romantic, persuades Arthur, as best man, to accompany them so he can have someone to talk to (Camille doesn't count). It could also have something to do with the fact that Alf is terrified of making the trip.
