I was on the lookout for an iPhone 5 for work, so it had to be Australian stock with a tax invoice (and payable via AMEX)
Mobile Made Simple in brisbane city have the iPhone 5 64GB on special at $899 (save $100 on retail). This is an instore price.
They are Telstra phones but are not locked (I am using Optus) and says they come with 24month Australian warranty.
Very happy with mine as cheapest I could find locally.
Kogan is grey import at $929 + shipping (no tax invoice - possibly no Australian warranty)
Isnt iPhone 5S release just around the corner or is it just a rumor ?
