Hey, I've never been to Australia but I applied to Sydney and got accepted. From what I've read and heard, the program is equal if not better than any program in the US. The program is AVMA accredited (as well as accredited by the UK, NZ, and Canada) so you would receive a good quality education there. Overall, it is an excellent university. And Sydney strikes me as an awesome place to live.
For US students, they don't interview (good thing because it would be a long way to travel!). I don't remember when the application deadline is for us- I applied this past summer (June I think). Remember that their semesters are on a different schedule than ours since its in the Southern Hemisphere obviously. So their year starts in feb/march, they get a break and then the next semester starts in august or some time around there.
I don't know what you mean by statistics. If you mean rankings, well for veterinary school I would ignore those. Aussie schools aren't always ranked in this journal and that report like US schools. If it's an AVMA accredited school, I think that's what is most important (unless you never plan on returning to practice in the US at all).
If you mean like GPA, GRE, and that stuff....well they don't require or care about your GRE score. They basically review your transcript, your major, quality of your program, etc. I sent in two LORs along with my transcript and details of my work experience and that's about it. I believe they are mainly concerned with your academic performance when making a decision. Hope that helps, good luck.
