In general, yeah, the university handbook is the way. Sometimes the department also has information on their webpage about specific pathways in that discipline. For ANU, check out here, here, and here.
If I did UMEP Physics at melbourne would I still have to do Foundations of Physics or Advanced Physics 1 & 2?
Do you think I could get access to second year physics courses?
Also what's the minimum possible time someone can complete the PhB in? Is 2 years a possibility?
Nah you'd probably be able to jump right into second year physics courses (quite a few of my friends did this). I did the equivalent with maths courses. (And lolz, Foundations of Physics is physics for bio students. The Further Maths of the physics world.)
2 years is pushing it. 2 and a half years is possible. Then add a year onto that for honours. You can't do honours in any shorter period of time than a year, and it's hard to do 6 ASCs and enough third year courses in less than 2 and a half years.
No need to rush it though, if you get too far ahead just go on exchange and bum around Europe. Worked for me
