In reply to pete davies: Lucky bastard, wish i was there, as for some useful advice, car buying is byfar the better option, although getting a nice motor that wont break down is another question, the oz experience (otherwise know as the big green f*ck bus) is for those people how are in their mid to early 20's, (generally gap yr students and people that should know better)
There's loads of climbing round sydney and the blue mountains (around an hour from sydney) theres loads of climbing gym's if the weather is crap, if your heading up the east coast (the usual trail) i climbed extensively around brisbane, there's also a few climbing walls in the city, the easiest crag to get to is kangaroo point which is right inthe city centre, the entire crag is bolted sandstone up to 20metres high, tie off bollards at the top of the crag, and its floodlit at night, there are bbq points by the edge of the river (about a 10m meter walk!!!)
Quite literally a climbers haven, the route's go from anywhere around severe to E4 ish (oz grade 10 to 26) there are various bouldering opportunities`the traverse of the main wall (about 200meters) is quite challenging, but hooking up with local climbers if you hav'nt got a rope is easy enough. Other climbing in queensland is possible (frog buttress, the glasshouse mountains) all within acouple of hours of brisbane, from there things get a bit thin, i have no doubt the are climbing opportunities abound in the state, they just hav'nt been discovered yet!!! If you get as far a cairns, there is some bouldering at trinity beach (about 10km north of cairns) there is also the barron gorge (take the road to kuranda to see the barron gorge waterfall)
I hope at least this has been some help to you, as for which dicount cards to go for, they are equally the same, i did find the Yha hostels a little on the "sterile" side (lacking atmosphere) apart from the one in byron bay (jay's bay) if you are looking for a bit of fun just follow your nose and enjoy (one hostel that i dont think is in the LP guidebook, the serpent hostel in cairns is just brilliant,air con rooms and mega large swimming pool, free minibus that will drop you in town) Its a nomad hostel and quite cheap $15 a night.
Enjoy anyway
