Not a problem at all. I am ex UTS. At least half the club members are no longer students. Most of them either went to other uni's or didn't go to uni at all. The club is actually set up as two legal entities, one for students, and one for everyone else.

It isn't just about it being too hot for walking, rather that canyoning can really only be done in the warmer part of the year, so for people like me who love this particular off-shoot of bushwalking summer is all about the canyons. A lot of bushwalkers seem to end up being a bit seasonal, with serious multi-day walks in spring and autumn, canyons in summer, XC skiing in winter.
