Just south of Brisbane...jeez Dan you saw what our conditions are like only a few weeks ago

Ok, so just so you don't get lynched, Queensland (even just south or Brisbane) is not NSW. Trust me, in these parts people have been burnt at the stake for less.
I concur with Dan, stay where you are. If you must come you will need some bigger sails, hard to say exactly what without knowing your weight. You will most likely need a bigger board than you usually ride over there as well.
