@Fuzz - There are a few things you could do. I was in a similar position to you when I finished college in Tassie. I had been round these forums making stuff since I was 12, and all I wanted to do was make games. For me though, that wasn't an option. UTAS had nothing in that field, and like you, Brisbane, Sydney and Melbourne were all a world away. I studied English Lit for a few years, then bummed around with a few 3D jobs in Launceston, before finding a Bachelors in Games Design in Brisbane. Jumped into that, and it kick-started my career. I didn't finish it mind you, but made some friends that are my new family.
The life of a designer is all about absorbing as much of the world as you can, seeing as many sides of it, and letting that all sink in. If you have the will, get into it. Either take that course at UTAS, or just make the move over to one of the bigger centres. I live (well, normally) in Melbourne, and the game culture there is amazing. Every month there is an IGDA meetup, everyone comes along and talks games, drinks beer, eats burgers, and generally has a great time. Immersing yourself in that culture gives you such a creative boost, man, you gotta experience it. You should come over for Freeplay this year. It's in September I think, and it's a really cool independent games festival. Lots of indies, good vibes, and great networking.
Studying games at Uni is really good, and it's worthwhile, but you get the real experience from getting out there and letting the world sink in. Make games, push boundaries, get out of your comfort zone. You are at a great time of life where you have so few responsibilities and so much potential. You can do that while at Uni (seriously, it's a good life), but you can also do that outside of it. In Brisbane, I moved into a house with 4 strangers, all who studied the same course as me. We made games, got drunk, and learnt a lot about life over those three years. They are some of my closest friends.
Games, man. It will change your life. Whatever brings you closer to that dream - go for it.
All this rambling doesn't really give much advice, but you are in such a similar position to me. You have all the power here, and there is an amazing world right on your doorstep.
