Macquarie also offer a games dev degree, but I would be careful of those. They (at least the UTS one) are essentially just IT degrees with a forced major. The games dev industry in Australia is not very big, so a specialised course might not be the best idea.
If you think your ATAR is going to be competitive I would definitely look into the BIT course at UTS, there are some students in there keen on doing software development and plenty of sponsors offering dev internships. Finishing a course in three years with a year of work experience and close to a guaranteed job is hard to complain about lol.
You just won't get the theoretical grounding that you'd get in a course like comp sci at UNSW which have the most reputable comp sci and engineering faculty/courses in the state.
