White Water Rafting
A question I hear a lot while out on my travels fixing broken computers in various tourism establishments is what there is to do here while it's raining. Now, forgive me for being rude but if you can't think of something to do here then you've got no imagination. However, have you ever considered white water rafting? You're wet anyway so go and get wetter in a fun way.
The Tully River holds some of the best rapids in Australia for your white water rafting experience. In the wet season it often flows so fast that even the instructors won't go in (although I did hear one say about the impending tsunami-that-never-was that he'd be OK because he was out rafting that day anyway). Thousands of happy punters can tell you that it's not as scary as you may think, it's a bit of hard work and a hell of a lot of fun so give it a blast. You won't be disappointed.
