Well what do you want out of the degree? strong conceptual and analytical skills as well as creative thinking and problem solving abilities? A good learning environment?
IMO, the first two years and probably some of third year units, you probably wont get this.
Regurgitation of formulas and principles and filling numbers into formulas is probably the bread and butter of the unit. There have been complaints about standards dropping and international students having some serious skills deficiency:

You will get some serious analytical work once you hit third year where stuff like Industry organisation, Contemporary perspectives of economic thought and economic history really gets into it. Unfortunately, they dont really teach stuff like Adam Smith, Ricardo, Friedman's and von Hayek's free market policies or Marx in the core units.
As for the 1st 2 years, most of the units overlap with accounting and finance courses as well as several of the 3rd year electives.
Its not a great experience stuck in an overcrowded room listening to answers from a Masters/PHD student who has only been practicing english for a few years.
As for the lecturers, they are great speakers and presenters (a few exceptions), but most likely, they wont be taking your tute.
Would i recommend you doing it?? do it with law and the intercontextual work u come across in law electives and jurisprudence really is enlightening stuff....
