Hello mate, there are quite a few aussies onboard already, so come and join in!
According to the tecky people who know things, it's more important to have a steady ping than a particularly low one.
Any of our antipodean pals around to chime in here??
P.S. I've played on ATAG_Wolf's server, which is actually his home computer, I'm in the UK, he's in Melbourne, so in terms of miles it works, but of course it depends on your ISP too. And all that.
