Well yeah - we are one hell of a long way from the rest of the world, that's for sure!! We like it that way - keeps us immune from undesireables like Migflanker and Coyne !! LOL.
That's why I am always amazed at the people that come here for a week or 10 days or so. It's such a massive country, and takes so long to get here, you'd want to make it worth your while!
Blair Athol is a suburb of ADL, so ADL is definitely the airport to head for. I know WN staff used to get ID100 with Ansett, but as they are now toast, I'm not too sure if Qantas give you anything or not. Do you have anything with Air Canada or United? Both fly down here daily and you can pick up cheap as chips internet one ways, planning ahead, with VirginBlue.com.au or Qantas.com.au Air Pacific from LAX via Fiji is an option if they give you anything - and there are worse places in the world to get stuck at other than Fiji if you did get stuck there!
Give us a yell for more info when/if you need it.
Also check with Randy (ORD correspondent.) He's WN and has travelled quite a bit out of the USA. He'd probably have some pointers for WN staff.
Cheers.
