Pilotdude,
start asking around at the banks you use already. Dress yourself up in a shirt and tie and ask to speak to the manager. Ask them about student loans for tertiary education and inform them of the payment structure for the course. You should be able to get austudy as well. Be prepared you will end up talking to alot of banks believe me. But when you manage to find one that is prepared to listen to you hit them with everything about the course, what it leads to and what your goals are.
If you are able to squeaze the money out of them make sure that its a loan where you don't start making payments until the course is over and your working.
