Re: rockclimbing cairns Not much around Cairns but there is awesome climbing throughout the east coast - in August and September you may find it too cold to camp in the Blueys, but Nowra should be fine
Best place to go near Sydney is the Wolgan Valley.
Great camping, soaring crack lines and beautiful outdoor setting.
You will find all the trad you desire from 5.2 - 5.11.
You will need a car - 2.5 hours west (past Lithgow).
There are good small cliffs at Berowra and in Sutherland.
Nowra has good shorter sport routes but not a particularly inspiring setting
Point Perpendicular has fantastic exposed trad and sport above crashing waves
Hope that helps!
