hamish225: they should land it somewhere thats not auckland. I know thats where most of the population is but what about somewhere around wellington?
if auckland had some kind of natural or man made disaster then that would be the end of outside communication accept for those with satellite internet.
For a trans Pacific cable, such as Southern Cross, Auckland is good because you can land the Oz facing cable on one side of a narrow isthmus and the Pacific facing cable on the other, and have access to Auckland. However, for an Oz-only facing cable, somewhere further south would be a very good idea.
If you are going to do that, it would be a great idea to also move the Sydney link down to Wollongong or some such, thus avoiding the single point of failure where, as I understand it every cable enters Port Jackson.
