Just to throw this out there though - medicine at UNSW is very very very competitive and you need an extremely high atar. I know they say you should choose your favourite subjects - but with the subjects you listed there, how sure are you that you can achieve (ideally) a mid-high 99 atar to be competitive for entry? It is easier to score higher atars with higher scaling subjects, so I would recommend replacing biology with chemistry and general maths with at least 2U maths (or drop it altogether) - unless you are confident you can score a mark near state rank with those subjects.
Good luck!
