I've attended La Trobe since Mar 2013 and what i've seen so far is a very satisfactory performance from La Trobe. Personally in my department (Computer Science and Computer Engineering), we have a broad range of talents and do very well in our area. Cannot comment specifically on Law as I haven't taken a single unit in Law, but i've had a broad range of experiences from Business to Accounting to Management to Mathematics, Statistics and Computing.
Feel free to check out mine and MJRomeo81's subject reviews in the La Trobe uni forum here.. To get a glimpse of what the subjects are typically like (obviously again, not Law but there's a mix of Faculty reviews).
However that being said, the uni is currently going through a restructure so there's most likely going to be job cuts etc. so whether or not that actually impacts teaching quality, well we'll see.
Overall though, I would say a 7/10. If you have any other questions about La Trobe, you can PM me, or MJRomeo81 (or anyone else that goes to La Trobe for that matter that are active members on here, just don't know any others haha).
