I have several friends currently doing medicine at UQ. They all love it. It's quite full on - two days a week they have 11 hours, the other days are probably around 5-6. From first year they start clinical at Herston. I know one that was accepted into medicine pre-grad (when they only had 50 places), you must complete a science degree in 2 years with a GPA over 5.0 (credit average) in order to continue onto your spot in med (I think he had a 6.85ish GPA). Others did GAMSAT, getting scores of 66, 68 and 72. As long as you've already completed a degree and graduated with a GPA above 5.0, the selection process no longer involves an interview but you are ranked by your GAMSAT score and offered a position from that.
So yeah, that's all I can think of at the moment. Hope it helps.
