Retrobiking is more of an underground thing here and the larger distances between places is also a factor to consider (geographically the UK is pretty small in comparison).
There's a small retro scene here in Hobart and the odd retro ride/gathering, but I can't comment for the rest of the country.
If you make it to Tasmania in your travels drop me a line as I'll be able to show you some of the best tracks/trails we have to offer.
A word of warning though, not a lot of the riding is truely retro friendly (well not in Tassie) so a modern dual suspension bike with disc brakes would be a wise purchase when you arrive.
Yeah, the retro thing is pretty quiet here in comparison to the UK. Can be a good thing, there are some bargains to be had - saw an old Foes LTS with Judy SL's and other high end retro kit sell for only $420AU (~150GBP) a month or so ago. Would have bought it had I know purchased the GT the previous week...
Perth has a good mix of terrain. Plenty of the steep, rocky stuff that really needs dual suspension and discs, but also plenty of traditional cross country stuff too (not to mention a 900km long distance trail from Perth to Albany if you're into off-road trekking). Not many big mountains strangely enough, seeing as we produce some of the best downhillers in the world.
