I was under the impression google had a cache in Perth as well, they certainly have peered via waix.

I can see you are in located in Adelaide via an internode DSL? and when I do the math on what I see to google (0-1 msec) and I add what I see to internode LNS in Adelaide (20ms) then I do an LFT to your PPP which shows a differential to the LNS of another 24ms for your last hop, when we add the internode latency to Adelaide, 20 + your last hop latency of 24 = 44-45ms..... which is the exact figure you are coming up with?
