Yeah, macquarie seem to be pretty good with offering lectures online and stuff. If possible, get in contact with some current students (maybe ring the uni and ask?) and find out what time time tables are like. I know UNSW isn't too flexible with that and it's hard to avoid 5 full days a week, but at UTS this whole year i've been 3 days a week with a couple days where im there for a few hours at most. The transport time is made a lot worse when you have to be in at uni every day.
As mentioned earlier, as long as you don't do some "Engineering Science" kind of course or a diploma you should be qualified by Engineers Australia and since it's accredited the course content and structure shouldn't be extremely different (in a bad way) among unis because of that. The GO8 unis, UNSW and USYD in nsw, hypothetically should attract the "better" academics due to the focus on research at them so you may have better lecturers there. But i've also read that stuff is irrelevant until post grad anyway.
