Id actually rather you didn't to be honest. We do very good speeds to everywhere. And I can say right now approx 2/3rds of our traffic is serving overseas without any complaints as far as I can see. We cover global news with writers from around the world, so we aren't "just" an Australia site, and would rather not be treated as so :).
PS. And you wouldn't do it to a US or Euro site would you :)
