I hate to ring the already dirging bell, but you're not the only one encountering this problem, Luca. Anyone going into a creative career path relies on 'getting discovered' to ever make any substantial amount of money, compound economic atmosphere issue aside. The upside to this is that there are numerous opportunities to find connections in the industry. You're not in the best part of the world for that, especially since EA bought up Pandemic and ran it into the ground.
However, you're very close to a major figure in the gaming industry, 2K Marin. I don't know how you'd feel about paying a visit to the studio in Canberra, but if were able to you might meet some people who could help you out. Whether it's a grunt UI artist or a design director, they all had to get their jobs somehow. Maybe you could speak with some of them?
Another potential lead: I heard recently of a company in Perth rising from the ashes of Pandemic Studios. The name escapes me, but I remember that they're going to be developing primarily for the mobile platforms like the iPhone and Droid. If I can find them, I'll add in the name here and maybe you can speak with someone there.
Just because I'm getting really wordy here (Don't usually get to talk about things I've read on gamesindustry.biz), I'll conclude with a little bit of encouragement: Don't ever forget why you're in the business! (Kid?) We all worked hard to be who we are, and some of us haven't got scraps to show for it! That doesn't make us stupid, or in the 'wrong line of work'. Things go wrong, constantly. It can be dramatically disheartening, especially if you forget about obstacles being part of the game. (Double meaning potential? Maybe.) I, for one, suggest picking yourself up and getting some shitty, mind-numbing experience doing a job that only slightly has anything to do with what you want. Then, with that under your belt, you can approach publishers with your ideas and a very impressive resume with years of experience in "Interactive Software Service Design and Maintenance". (Which is really just like making the coffee, setting the cup on a napkin on the desk, and cleaning it up later; except at a development studio.)
Alternatively, you could join the rioters in England over your extremely high cost of tuition...
