Robyn,
Drop me an email, I'll get you set up. Apparently I just missed you, we were in Sydney for a Vegas VASST just 2 weeks ago, sponsored by New Magic of Australia. We did Sydney, Adelaide, Melbourne. I'd wanted to get up to Brisbane, but couldn't draw a large enough group to make the journey worth the cost. Anyway, I've a list of Vegas users that are fairly 'pro' in Australia/Central coast. The best is in Palm Beach, about 90-120 mins from you.
