Probable change needed to the Aust zone files

This is pretty minor, and may not be worth bothering with, but we do try to cover everything, so ... I was told recently that the town (district probably) of Kunumurra, in far north east Western Australia has switched its time zone to be the same as that of the Northern Territory instead of using WA time (they're just over the border, and the WA time zone is wildly inappropriate, so it makes sense). I hope to check this if I can find someone to check it with, and see if I can discover when it happened exactly. I wouldn't be in any great hurry to get this fixed, this is going to be one small town, and I would doubt very much that anyone there is running the tz code in any form... kre
