I'm not 100% sure how many actually apply, however a lot of the exercise sport science kids and a lot of the health science kids (majoring in movement) apply for masters of physio.
And they're not easy courses either, many of their subjects are actually similar/the same as undergrad physio which are really difficult such as FMA, FMB, body systems and biomechanics so transferring to physio/getting into masters isn't an easy path to take.
UWS also has a masters course, and unlike the stereotype of UWS, their physio course is very respectable as in the health sector, it's not about where you go to uni but about you as a person and your experience.
