Personally - i would say you're better off going to UWS Law and then if you don't like it, transferring out after 1st year to another uni, rather than doing another course and then transferring.
Partly i think this is better as, if you really want to do law as you said you do, you're better off doing a law degree to start with as there is always the possibility that you won't be able to transfer in from the other course, so even if you're not at the uni you most prefer, at least you're doing what you want to do.
As far as if the law course is any good - you learn the same stuff just about everywhere, just like everywhere some teachers are awesome and some suck, just like everywhere some students are committed and some are rude, disrespectful, lazy, cheats - i suppose it depends on what kind of career you want out of it, but generally, provided that you work hard and apply yourself and tack on some practical experience in the work place, you shoul dhave no problems finding jobs with a UWS law degree.
The only thing i would say that is limiting about the UWS degree is that there are fewer electives to choose from, however you have to balance that against there being greater flexibility in timetables compared to some other unis, that and they are gradually adding units to the law degree so there is a bit more choice next year.
Yes you do have an advantage at another uni if you want to work at certain firms because they are very anti-UWS, but i highly doubt you have your heart set on working for a particular firm?
As Demandred said - they are pretty demanding as far as assessments go - we have been told 'unofficially' that this is in order to ensure that the students are of a better quality sort of as a way of making students more competitive with those from other unis. It can be stressful at times, but most people seem to make their way through it all - you just need to plan. And having lots of assessments isn't necessarily a bad thing in a way - it means you have lots of things worth less marks, rather than one or 2 worth lots of marks so if you s crew one up its not the end of the world.
Essentially it comes down to the same thing at every uni - you need to work hard to get good marks, get some experience, try out some pro bono work and make as many connections as you can. Being at UWS, as long as you do these things, won't prevent you from getting jobs - the fact that Justice Kirby's Associate is an Ex-UWS student i think shows that
Yes she was very very smart, but still from UWS
EDIT: Where do you live? because convenience is a huge factor too - if you live say, an hour and a half from maquarie uni, and you have uni 3 days a week, do you really want to spend 9 hours a week travelling?.... it is a big factor to consider because if its a task in itself getting to uni and back, unless you can get lots of work done on buses and trains you will start to hate it
