Hi Richard,
If we're talking one-way latency as seen by the network then here's a
sort of strip maps of places of interest
Singapore --25ms-- Perth --14ms-- Adelaide --5ms-- Melbourne --6ms--
Sydney --25ms-- Seattle
Sydney --10ms-- Brisbane
Melbourne --5ms-- Hobart
Adelaide --18ms-- Darwin
So at first glimpse the spec excludes a single overseas datacentre
serving all sites in Australia.
The situation is a bit more complicated then the raw figures indicate,
so feel free to give me a call (tel num is on the AARNet site).
Cheers, Glen
