Not a lot of snow on the Gold Coast Brendan. I suggest you get fitted close to where you are skiing. If you are skiing in NSW (Thredbo/Perisher) I can highly recommend Richard Mould at Eiger (Nuggets Crossing at Jindabyne). He is definately one of the best bootfitters in Australia. The only downside with Richard is he doesn't have a huge variety of boots (mainly Salomon and Lange). He is also happy to work with your existing boots.
If you are skiing elsewhere I suggest you throw your question up at http://forum.ski.com.au/scripts/ulti...ultimatebb.cgi
or here http://www.snowatch.com.au/forum/cgi-bin/ultimatebb.cgi
Make sure you book an appointment with the bootfitter, give yourself plenty of time (3-4 hours) and be prepared for some return visits for adjustments.
Alll that said, nothing enhances your skiing experience like a properly fitted pair of boots.
