Mate I'm from Australia and had a HT performed in Canada about 5 months ago. I absolutely implore you to save your money and buy that plane ticket and have your HT performed by a reputable surgeon in the US or Canada.
There is NO and I repeat, NO quality HT surgeons in Australia at present.
This surgery will be a life changing event, either in a good or bad way. If you get the surgery performed in Australia you will more than likely see it as the latter.
My tip for you is to continue saving your money, do some thorough research (a good year or so) and do not choose a surgeon based on convenience or personality. Choose them solely on results and reputation.
The only 3 surgeons/clinics I even considered to have my HT with were Hasson & Wong (Canada), Dr. Feller (New York) and Dr. Rahal (Canada). I eventually went with Dr. Rahal in Canada and I'm extremely happy with my results. The three aforementioned all have great reputations and have the results to back it up.
Let me state for the record that you have been warned, don't make the mistake many people make of choosing a HT surgeon because it is close proximity or it is cheap. Then they complain they have less than desirable results.
