i don't think that it's nearly impossible to do it, and you don't really lose anything by trying. i thought it would be heaps harder than it was, even with the rural stream of application and didn't expect to get in. but that's just my opinion about my own experience. yes, i did have to write the essays for unsw, and it took me awhile to work out what to write as well! fot the work experience one i wrote about the voluntary work i did at the local vets for 18 months when i wanted to be a vet and how that made me want to do medicine. then about the weeks work experience in year 10 at the local hospital and week at the pharmacy. i think you just need to explain what you learnt about yourself in relation to a medical career in these periods eg. "I learnt that a certain attitude is necessary in order to help someone open up about often very personal issues, a lesson that I think will help me enormously in my future career as a healthcare professional." it's all just stuff i did actually learn, but didn't realise 'til i really thought about it. for school and community activities i just talked about eisteddfods and school plays and things like clean up australia day and the red shield appeal. you just need to kind of link it all by expressing how that sort of stuff has influenced you and your views. anyway, good luck! i hope my ramblings might help you in some way.
