Go for the UNSW co op accounting, cos its 4 years so you get more money. Also, you do 18 months of industry training rather than the 12 months only, offered by UTS BAcc. Plus, UNSW i hear is more recognised than UTS by employers.
@OP - the pros and cons are very obvious. I guess the only other one no one else has mentioned is transport - it'll take an extra 15min to get to UNSW.
