Your professor is correct in saying that UTS journalism is the bomb. Not many people drop out of UTS journalism... in fact, a lot of people from other UTS communications degrees are trying to transfer in to the journalism major after the first year. It is a very competitive course to get in to.
I was worried I wouldn't make it in to journalism at UTS when I got my UAI, so I asked all about the chances of transferring etc if I missed out. Apparently, it's extaordinarily difficult. The advice I was given was if I didn't get in to journalism at UTS I should do social inquiry at UTS with journalism electives as that would also open doors in to a career in journalism, so maybe that is something you could consider if you really want to get out of Wollongong to UTS and don't get a transfer in to the journalism degree.
I think what would be more important than just a high grade point average to transfer to UTS journalism would be if you could go to the faculty with a portfolio of published journalism work, or if you had appropriate work experience in the industry. This would show them that you are really gung ho about journo.
If I were you I would definately contact the faculty and ask them about the requirements.
I'd also advise you that USyd journalism sucks. If you are serious about journalism and don't get in to UTS, the next best course is at CSU Bathurst. USyd journo students get all theory and no practice, and what really counts when you graduate is how fat your portfolio of published work is. I have been at UTS one semester and have already had stuff published, where people at USyd apparently don't even start writing journalism stories until 2nd or 3rd year. At UTS, in the journalism 1 subject, you have to produce a news story almost immediately, which is great.
Anyway, I think the best bet is to ring the faculty and get some information about the requirements. They should be more than happy to help you.
