FYI - The TPA is an act to govern trade between businesses. As you're quite likely not a business, consumer law applies here, if you engage in a course with Griffiths University. Specifically, Queensland Consumer Law (Fair Trading).
I don't have an extensive practice in the area but the TPA applies to corporations who engage in trade or commerce generally.
Some universities are undoubtedly corporations and some are not. In the latter event the Australian Consumer Law still applies.
It's all there in the schedules to the TPA amendment Act No.2 but it's not as exciting reading as "the Checkout" is viewing.
