Both are on pre-order now and reach stores on Friday 18 September. The headline change is a new heart sensor, but the detail that matters most for Australian buyers is a feature that is not switched on here yet. **Quick answer** Series 12 starts at A$649 and Ultra 4 at A$1,349, both available from 18 September. Apple says the new sensor reads your heart rate every five seconds and adds a daily readiness score. Hypertension Notifications, the blood pressure alert feature, will not be available in Australia at launch on either watch. Apple says further regulatory clearance is in process. ## Prices and Dates Apple’s Australian newsroom lists Series 12 from RRP A$649 inc. GST and Ultra 4 from RRP A$1,349 inc. GST. Pre-orders opened on 10 September and both go on sale on Friday 18 September. Series 12 comes in 42mm and 46mm sizes; the price rises with size and case material, and the base price quoted is for the entry configuration only.

Those readings feed a new readiness score, a single number from 0 to 10 with one of four recommendations: Recover, Pace Yourself, Ready or Go For It. Overnight vitals now include recovery HRV compared with your personal baseline. These are Apple’s descriptions of the feature set. We have not worn either watch, and the accuracy claims are the company’s own.

No Australian date is given. If blood pressure alerts are the reason you are upgrading, that is the line to weigh before you order. The new Audio Intelligence features, including Live Rewind and Siri Recap, are listed as not initially available in the EU. The releases do not say either way for Australia, so treat those as unconfirmed here until Apple’s Australian product pages list them.
