Access to education in Australia is definitely better - for most courses entry is egalitarian - students are ranked and preferences orders determine what courses you get offered (it's very different to the US system - you nominate the course you want to take, BS, BA, including the major area and while you can transfer later, relatively few do). Obviously art and music courses often have an audition requirement, and exceptionally high demand or courses deemed to have a desire for 'suitable' people (without getting into a debate about that), such as medicine may also have an interview requirement.

However, the general philosophy is the Higher Education Contribution Scheme. This is a fee that is largely flat, only paid on graduation, as an increased income tax requirement (a few percent more), if and only if your salary is above a threshold. Drop below that and you're no longer paying on your HECS debt. However, you can also voluntarily opt to pre-pay your debt for varying discounts. When I went to school (mid 90s), this fee was $1800/year. Any course at any university, from liberal arts at a country college to medicine or law at the most prestigious of institutions.
