I am getting some weird traceroutes on my mac to google. It appears to go all the way to sydney? However when I reboot into windows, I get a correct traceroute to somewhere close by with far fewer hops, a max of 30ms or so. So what could be the cause of this? Clearly something on my mac is making it prefer the longer path. I've tried flushing the dns cache but it doesn't appear to change anything.

How odd .I don't understand it either, If you've flushed your local dns cache you would think the traceroute would resolve in xp and mac os to the same address. Goodness knows why one is ending up in Austrailia. I presume your external DNS servers are the same for both OS's

Welcome, change both O.S.s to use the OpenDNS servers (208.67.222.222 and 208.67.220.220 ) and see what happens then, you change back to the original DNS servers later
Thanks guys I fixed the problem, I never thought to check that I had hard coded my dns servers into my mac network settings when I was back in Australia. :-\ No wonder it was resolving to something back there
