Hey 1292,
I don't have any experience applying to UNSW med, so someone with experience might be able to give you a better answer.
Why do
you want to be a doctor? What kinds of experiences / events (if any) have shaped your decision? Talk about why you think medicine is right for you, with reference to specific aspects about being a doctor (e.g. doctors diagnose diseases, more in depth with the biomedical sciences than some other health professions). For the second question, you could potentially write about some experiences in life, the lessons you've learnt from them and how they link to your desire to study medicine / be a doctor.
With the word limits, it might be helpful to write answers to these questions and summarise them to cut them down to the word limit in order to end up only including the most important details).
From what I've seen, there have been a few people who have applied to UNSW med on this forum, so it could be helpful to PM them. Having a google, using the MedStudentsOnline forum and PagingDr (good for past interview questions) forums might be of use too.
All the best
