It's pretty good, ranks just as highly as Melb and higher than Monash. Don't be fooled by the low ENTER requirement, loooooads of people fail at commerce/finance/economics courses at ANU. They definitely don't make it easy...
You have to apply through UAC instead of VTAC, which just means one more form to fill out. So you get offers from both NSW/ACT unis as well as Vic unis if you apply for both states.
Full academic scholarships (= National Undergraduate Scholarships) give you $10,000 a year at ANU, but you need around 99.60+ to be offered one. The school of business and economics at ANU also offers $2000 scholarships (my friend who went to Wesley has one) but you still need to achieve pretty highly (95+ at the very least). A lot of people have Centrelink in order to pay their accommodation fees.
Entry is just an ENTER of 75, probably at least 25 in English too, though I'm not sure. You will have to do a bit of maths at uni though; a lot of people who've done no calculus before fail.
Erm well I think that's about it. Feel free to PM me if you have any other questions ANU or BComm wise, I have plenty of friends here who do that degree.
