UWS, esspecially Parramatta, is picking up a decent rep. I saw both UWS Parra and UTS Kuring-Gai (for Nursing though, so I know practically nothing of the Marketing degrees) and UTS KG was a nicer place in general - unlike Dingo, I liked the fact that KG was surrounding by the National Park, wereas Parra was an 1800's orphanage/mental insitution.
That said, if you don't live in the Northern Suburbs, then it's a royal pain in the arse getting to KG - train to Linfield and then a 20 minute bus trip from there... I know people travel a bit to get to Uni, but 2 trains a bus is a pain in the arse as far as I'm concerned
Parra is easy to get to, Trains running constantly, buses ect. KG is really out of the way.
Unless you plan on going to KG and then transfering to City Campus for second year...
Social life as well, I'm told UWS more of a social life, compared to KG's and CityUTS practically non-existant one
