Actually, the parts of the HSC Physics syllabus that are crucial for physics study can be learned in closer to 0 minutes — because most of the syllabus isn't physics and is irrelevant. This means universities are forced to teach physics from the ground up. More important is your mathematical ability. If you're strong mathematically, you should be able to pick up the basics.
In terms of physics, Prelim Physics Moving About is the most important module for university physics (like concepts of vectors, momentum, impulse, work, etc). Most of these concepts are defined in terms of vectors or calculus, so again, if you're mathematically capable, you should be able to pick these stuff up.
