Ok, I got into UOW through early acceptance and I was never asked for an interview and I was given guaranteed acceptance... So I think the interviews are only for those borderline cases where they just want to see you and talk to you before seeing if they'll accept you.
If you have any questions, just ring the appropriate people's numbers which you should have from the application forms etc. If you don't know, just ring the uni and chase around until you find the right person.
