Looks like as same as the last month's Telstra day deal prices: iPhone 13 $350 off and pro and pro max versions $250 off. Has the outright buying option and offer valid until the 15th of August. Probably JB-HiFi will price match as last time, OW will price beat if you are lucky!
PS: If you could get a price match from JB-HiFi don't forget to use discounted gift cards to pay! (eg: ShopBack has 2.5% off JB gift cards that you can buy right away)
Only Boost because Boost uses Telstra's billing system. We used to get Telstra Plus points with Boost renewals (but Telstra closed that loophole long time ago). To download the invoice for my Boost renewal, I actually go to Telstra site.
