if i were to study at monash next year, how do i become a student ambassador? is it as simple as signing up/volunteering?
Could somebody also tell us what a student ambassador does?
Look out on my.monash for the volunteer dates, faculty reps advertise at different times as per faculty.
Ambassadors just stand around and help people in general, giving directions and that sort of thing. The faculty reps are the ones who give course info, advice and share their own experiences 
Anyways, I'm a student ambassador this year,so I can tell you more about the process. So, generally at March, the my.monash website advertises to people who want to be student ambassadors. They'll ask you if you have any previous experiences as a volunteer, or if you're involved at any clubs at Monash. They'll take preference to people who do have those things, but I would say the most important factor is that you make yourself sound really really keen to help out and give something back to the uni!
You just submit your details, then if it's good enough, they'll do an interview, and passing that, congrats, you're an ambassador.
We actually do a number of things, such as giving out info at uni (like, bags and maps). The most important thing we do is ensure NO ONE, gets lost. But if you ask us a bit more, we also talk to you about your futures, career paths, life experiences at uni and such.
I think, the best thing we do is actually promoting Monash is an absolute positive light, and make your open day experience as enjoyable as possible. Hopefully everyone did enjoy the day (apart from weather).
(Yeah, we also tell you to try the Peri peri chips, you can't go wrong with those)
Oh, well, you do get nice stuff in the end. We got nice free breakfast and lunch, a certificate of participation and gift vouchers from Coles Myer group, $100, mind you. And you get to make new friends! So being an ambassador is really worthwhile, do try out to become one next year!
