can i just clarify one thing? outside of nsw, not many people care about unsw. like its v prestigious in nsw, especially b/c all the james ruse kids want to go there, but it barely meets a blink when i spoke about it 2 my high ENTER friends in vic, etc. (though they were happy for me to get an interview there- just as happy as when i got interviews/places at other unis though).
look at the courses, see which ones u like, and order your preferences accordingly. remember u only have to preference med schools according to each state, so...
VTAC: have 2 decide if u'll put melb or monash first?
UAC: unsw, usyd, uncle, uws, anu provisional first? which order?
QTAC: uq, jcu, bond first?
SATAC, TISC, UTAS: luckily decision is made for u as there's only one med school in each of those
remember u could concurrently get offers from uac, vtac, satac, tisc and utas (if u were a lucky bugger).
