Not wanting to burst any bubbles, but I wouldn't count on getting a Brisbane spot if you get through, I'm from Brisbane and they sent me to Melbourne, along with a few others, and the most recent course that did start in Brisbane has mostly Melbourne people apparently! Very silly, especially since they pay a moving allowance, they could have saved themselves quite a lot of money.
But I'd consider it a win either way for you, Brisbane means you stay at home, Melbourne, you get to come to the college and be with a lot of other people doing the same thing, which is helpful, plus I've found not being at home has removed a lot of distractions as well!
