I've been enrolled in the ACU one, so I can speak personally about that. It has work experience from the first semester which consists of you finding some gym and telling the uni. Not actual clinical placements which they should be doing. It is also more focused towards PDHPE, despite having an exercise science stream. The best example of this is that every semester you do two additional units (not HECS), which are sport units, e.g. swimming and weight training, cricket and soccer, etc. They also do not allow you to pick your classes (something which USyd also shares) so you'll probably end up with a timetable where you have an 8.00am lecture, and a tutorial. Then a four or more hour break then another set starting at around 4.00pm and not finishing till 6.00pm. This was my timetable three to four days a week, plus on the other day I'd have one and only class which went for 50min. This is because they allocate classes based on alphabetical order. Oh, and they also preach religion to you, believe it!
I've heard good things about UWS, and you can select all your own classes.
I'm in the UNSW one at the moment, and hands down it's the best, IMO. You have the same freedom to select your own classes, (well the straight science ones anyway). It has it's own rehab centre that you can do placements in, which is run by the president of the NSW chapter of the Australian Association of Exercise and Sports Science (AAESS), and it's in the medical faculty (not really important but it sounds good). It also gets you started on exercise physiology straight from day one (unlike the UWS and ACU, where you only pick your major from second year onwards from sports studies, exercise science, sports management or PDHPE), and it is a four year degree with imbedded honours, unlike UWS, USyd, and ACU.
