The UNSW coursework is pretty good. I have only done three units so far, and they have been interesting and relevant to my own career, however..
One criticism I have is that some of the course material and readings are around 10 years old; they haven't been updated since the course material was written. I imagine the course co-ordinator's they use are casuals and most are probably not paid to spend a lot of time reviewing the material and bringing it up to date. Some of the units could have benefited from some basic proof reading! You don't expect to pay $2880 for a course unit that is riddled with errors, and that you would be embarrassed to submit yourself.
Like most things in life though, you will get out of it what you put into it. From what I've heard about other uni's, they are pretty much the same. I believe 2/3 of uni staff these days are casuals. That's where the rot starts, the focus is on the income via fees, not the product which requires continual investment.
