Besides the research opportunities, is there a big difference in the core subject material between various universities? i.e. would going to Monash instead of ANU undermine my knowledge? I've been taking a look at Monash's research opportunities in astrophysics, which seem pretty good, although I wouldn't want my basis in physics and mathematics to be compromised.
On another note, whilst CSPA has the areas of research I'd be interested in, does anyone have any idea how likely it is to get an opportunity to do research during the undergraduate degree?
Also I hear it isn't necessary to do any extensive, specific study in astrophysics in order to do it later on; how true is this?
