If you are doing accounting or microeconomics, I can assure you you are already ahead.
Accounting: Principles of Accounting and Finance
http://www.lib.monash.edu.au/collections/monash-authors/2010/9781742167008.htmlMicroeconomics: Economics by McTaggart, Findlay and Parkin (I think 6th edition is latest). If you are not going to do Macroeconomics later on, just buy the microeconomics text by the same authors.
Bus stats: lecture notes sufficient
Management: Management by Samson and Daft (3rd ed)
Don't know about the others.
It's not necessary to do anything before the semester start for either subject because you won't know what to read (unlike VCE you don't go through the whole textbook but read certain sections). Accounting is basically VCE accounting taught from scratch. Micro doesn't follow the textbook chapter for chapter and your most useful resource will be lecture slides.
