Option 1.
Not as good as the $150 off from Telstra but you should be able to price beat from Officeworks (who are refusing to match Telstra) bringing down the price for the iPhone 14 plus 128gb to $1,405.
Or option 2.
If you have Qantas Frequent Flyer points they currently have 30% off David Jones digital gift card. Can only use your points no cash option. Gift card took 10 min to come through. 70k points = $500 gift card, 140k points = $1,000
Just did a price match with Telstra a couple of days ago. The officework person said they allow Telstra membership deal no worries. Just a FYI not sure on how true it is.
