well, you can start off reading the transfer forums here on BOS...
What you need to know is all on there, but basically you go through UAC again.
Issues such as entry mark, academic credit are all explained there. There is no UWS policy or anything you need to consider really accept you need to get a proper academic transcript and such if you na tot get academic credit.
A really good thread is this :
http://community.boredofstudies.org/330/transfers/45647/topic-university-transfers.html by Frigid on the BOS forum. It should explain alot.
Antoher thing is to check UTS's entry policy first, whether they use GPA only, a mix of GPA and UAI and any other factors regarding entry. Than its just a matter of aplying and waiting just like yr 12's did throught UAC.
