hi. monash med alumni here. when i came here i applied and paid for UMelb biomedafter monash med accepted me (on 19/12), I simply asked UMelb to refund as they can not offer me a medical degree there (because its postgrad) and they refunded.
so as long as UQ can not offer med degree for you (given you got into monash med), they will refund the deposit.
i hope this answer helps
