Actually we do use geo-IP in the backend dns for mirror.centos.org - using 
powerdns and some custom perl.

That looks at the users location and will give a relevant mirror - however 
as we only have mirror servers in the us and eu it is prety moot for .au

We use that because it can give out one of a random list oif mirrors and 
thus spreads the load, whereas previously both yum and up2date hit only 
one of the set of mirrors in rrdns - due to a bug in the python libraries, 
and so all the load was taken by one server.
