Thanks so much for your replies Julie and Dave!!! And double thanks Dave, should've known I would have bumped into you here seeing as how I got this website off of you

Just by going off everyone's advice and suggestions, it sounds like Empress is the one to do! But I trust that I'll be coming back afterwards for more. It's too bad there's nothing here in Queensland or else I wouldn't have to travel as far! The closest would have to be abseiling adventures which I'm looking into and would hopefully provide me with more experience for the harder canyoning trips in future.
I'll be going there in December so I'm pretty sure it'll be warm and sunny by then. It was above 30 degrees here in QLD so it looked as if we skipped spring and got straight into summer... can't wait to see what the weather will be like once the official season starts
