Decent deal if you're already with Telstra with some Telstra Plus points and looking at upgrading to a newer iPhone. It's hard to find the 256gb or 512gb iPhone XS models in stores now but I found they are still available through the Telstra Plus shop.
The following are currently available:
iPhone XS 256gb (Space Grey) $1,128 + 20,000 points
iPhone XS 512gb (Space Grey or Silver) $1,512 + 20,000 points
iPhone XS Max 64gb (Space Grey) $1,080 + 16,000 points
iPhone XS Max 256gb (Space Grey) $1,296 + 24,000 points
Why would you get one of these when the iPhone 11 isn’t much more?
