Pretty ideally UNSW (ASB has a solid reputation and connections if you want to go into like IB or something above commercial firms), though for jobs in Big 4 commercial/auditing/accounting firms they tend not to care much about the uni you went to.
Without bias to UTS though (I'm a UTS Business student), strictly on an objective level the UTS Business school was recently the first Business school in Australia to receive a 5 star rating on the international QS rating system (source:
UTS's star rises in latest QS university ratings) so you probably can't go wrong with UTS Business. Plus our Bsoc is one of the more active uni business society's (probably second to only UNSW Bsoc) and has very strong industry connections and relationships with HR departments of the Big 4 accounting firms, some of the commercial Big 4 banks and we're rolling in some new sponsors this year too which are some pretty big names.
