Rightarmbad's advice is good. Ask the question regarding getting to Frog Buttress on www.qurank.com/. Get a bus or train to Brisbane and meet up with one of the Qurank locals there. September in the 'bungles can be brilliant and there are lots of great climbs which can be completed in a short day - not that the days in September are particularly short. Don't believe otherwise. Not going there because it may be cold is a bit like not visiting Scotland because it might be raining. It's a great place to visit anytime.
