Jetstar's 2 for 1 deal

Jetstar are having a two tickets for the price of one deal at the moment and we just couldn't resist. After agonising over which destination to fly to (Hobart, Christchurch, Queensland) we eventually decided on a winter trip up to the Gold Coast. Now, I don't like the Gold Coast, but I do like water slides and have insisted that if we visit the theme parks then one of them has to be Wet'n'Wild . I've never been there before, but it's a long time since I went on a decent water slide.

I wish that Jetstar flew directly to Perth or Darwin from Sydney. I haven't visited either of Western Australia or the Northern Territory. Winter is the ideal time to visit the latter. We do want to visit Tasmania again, but it would be more pleasant in the warmer months, especially as we want to go to the west coast.
