Hi,
I'm in Sydney. Did you buy stock or BTO?
I ordered BTO July 9, was looking at mid-October after repeated delays. Through some negotiation with Apple I got mine by mid Sept.
Best bet would be to ring a few suppliers and check on how their supplies are moving. I know that Mac Centric in Chatswood has had stock versions, and also Computers Now in N Sydney have recieved stock versions. BTO seem to be a problem.
Call Apple Australia on 133622 and speak with Customer Care. They may be able to tell you where in the queue you are if you can supply them with your W order number.
PS, they are worth the wait 😉
