There is one other thing... the roads. He won't be riding on supersmooth hotmix for any great length of time no matter where he rides in Oz. He needs to be able to ride on some of the crappiest surfaces if he's going to return home with all his skin intact. He will have to contend with verges and cycle lanes filled with debris (eg logs, girders, etc), numerous potholes, loose paving, enormous cracks, corrugated surfaces (especially on sharp bends and steep descents), animals (live and not so alive, some poisonous and cranky), oh yeah an the odd cranky motorist. [EDIT] and we drive on the correct side of the road, which makes crossing intersections interesting (and sometime spectacular) for the unsuspecting tourist
