AARNet has nothing to do with charging anyone other than the  
University - not students, staff, or faculties.  AARNet don't charge  
an "excess use fee" as such.

AARNet publish a BGP-extracted list of "on-net" IPs - that's IP  
addresses which are routing within their network.  Most, possibly all,  
Universities use that to differentiate charging to students and staff  
(where charging can be quota management or charging dollars).

If students are downloading personal content at home, then I'd imagine  
most Universities would count that a policy success - the AARNet  
network is designed around providing good solid research/academic  
access (and their speeds for that are unparalleled in Australia), not  
around commercial 'net access.

Disclaimer:  I don't work for AARNet, never have, but we deal with  
various Universities for billing and quota management, so I have a  
passing knowledge.  I'm certain there are better-qualified more  
knowledgeable people than I on this list ;)

I don't know whether the peered locations are counted as on-net - it  
wouldn't surprise me if they are.

(Incidentally, _most_ Universities are quota'ing students and charging  
something to individual departments/faculties based on the total per- 
year AARNet charge and each faculties' proportional use thereof.)
