What ever flying school you think you might consider doing your flying training you must do some thorough background checking. What is the experience of the instructors? does the training school have a demonstrated record (names not just numbers) of graduates employed, and where were they employed? how long do the instructors get to spend with you for pre- and post flight brief for every hours flights?; what is the cost breakdown and how much do you pay up front (never pay a whole course up front, but progress payments may be reasonable, check the fine print); how is the theory delivered and at what cost?. Check to see what training fees include (landing fees, instruction, fuel, theory, repeat flights...) and what is not included.
Whether you will want to use a government loan (HECS Help or FEE-Help; make sure you understand the difference) will depend on whether you have cash up front (a rich uncle scrooge, family savings or personal savings) or need a loan. The government loans to universities are always loaded with "on-costs" which are added to the actual costs of training, however even training organisations without government loan affiliations will often still charge comparable amounts. The practice of training on weekends and earning through the week is inefficient and not conducive to building flying capability quickly or effectively. So if young and penniless the loans are a way forward. (It takes several years to get a trade qualification, say as a sparky, and then several more years to save cash, so this is a very long pathway).
Not all universities are the same in terms of entry criteria, and postgraduate employability. Check on both, rumours abound; an earlier post suggests UNSW ATAR is 70; not long ago I believe it was ~80. A University degree does indicate some measure of ability to absorb and understand technical information and also some maturity of living and working with others, so can add to employability for some types of flying positions where this is useful. Visit the school on open days and also get a personal interview. Try to get to talk with current students in private to get their real opinions.
It is your pathway to choose, and every path is expensive in cost, and of course takes time ( and precludes or postpones another choice). Good luck
