Townsville's nice in the dry season, but so's anywhere in the tropics. Likewise, anywhere in the tropics is 5hitty during the wet season. I've lived in both the tropics and the southern states of Oz and smack in the middle suits us best. Been here for 20 years next month. We get humid weather occasionally at this time of the year, particularly when there's a couple of tropical lows converging to the north west. A couple of stormy nights and +100F days and life gets a little sticky. Still rather be here though than anywhere else
Let us know if ya gunna come look at the big rock in the middle of Oz if/when you do come over. Be sure to come over in the dry (our winter), the weather is much more hospitable, and I'll take you to places that the ordinary tourist don't get to see.
BTW, the offer is good for anyone that comes visit me
