The short version
Six things to hold onto.
- The Series 12 starts at $649 and the Ultra 4 at $1,349. Last September the Series 11 launched at $679 and the Ultra 3 at $1,399, so the entry prices are down $30 and $50. Titanium is $1,249 both years. The SE 3, which is not new, stays at $399.
- The full Series 12 ladder runs from $649 to $1,689. Add $90 for the 46 mm case, $150 for cellular on aluminium, and you are at $889 for the largest aluminium watch with its own SIM. Titanium is $1,249 and $1,339; the new ceramic finish is $1,599 and $1,689. Cellular is included on titanium and ceramic.
- The cheaper price is mostly the currency. The Australian dollar bought 66 US cents at last year’s launch and 71 cents on Thursday, an 8 per cent gain. Our arithmetic says that movement alone was worth about $49 on the base Series 12; Apple passed on $30 of it. The premium over a straight conversion plus GST is about 5 per cent on the aluminium watch and about 16 per cent on titanium and ceramic, which is where the margin lives.
- Hypertension notifications are not available on the Series 12 or Ultra 4 in Australia. Apple’s Australian releases say additional regulatory clearances for these models are in process and expected later this year. The feature works today on a Series 9, 10 or 11 and an Ultra 2 or 3, because those are the models the TGA listed in December.
- What is actually new is the sensor, not the case. The S11 chip and a rebuilt Health Sensing System read heart rate every five seconds all day and heart-rate variability up to 24 times more often than before, feeding a 0-to-10 Readiness score. Apple claims the most accurate heart-rate sensing in any wearable; nobody outside Apple has checked yet.
- The headline AI features are a beta for late 2026. Live Rewind and Siri Recap, which turn the last 15 seconds of a conversation into text or summarise a longer one, need an Apple Intelligence iPhone 16 or later, not the 16e, and will not ship until later in the year.
What went on sale yesterday
Three watches, one software release, and one carry-over. Specifications below are Apple’s own claims from its Australian press releases of 10 September; none has been independently verified as at our capture date.
Apple Watch Series 12. The chip is the S11, which Apple calls its most powerful wearable chip; MacRumors lists 4 GB of memory and 64 GB of storage. The change that matters sits under it: new optical and electrical heart sensors with larger electrode surfaces, photodiodes arranged in a ring and larger, more efficient green LEDs. Apple says the system measures heart rate every five seconds continuously and heart-rate variability up to 24 times more often than the previous generation, splitting HRV into a Recovery figure for daily strain and an Overall figure for longer-term health. It cites a study of more than 1,000 participants in which, it says, the Apple Watch showed the highest accuracy across the leading wearables tested. On top of that data sits Readiness, a single 0-to-10 score each morning built from recent activity, training load, vitals and sleep, with one of four recommendations: Recover, Pace Yourself, Ready, or Go For It. Apple also claims more accurate step counting from a redesigned pedometer, and better distance on indoor workouts.
Battery is quoted at up to 24 hours, the same as the Series 11, with 38 hours in Low Power Mode; the improvement is at the edges, with up to 10 hours of outdoor workout tracking (25 per cent more than last year) and 15 minutes on the charger now good for up to 12 hours (50 per cent more). The display peaks at 2,000 nits. Cases are 42 mm and 46 mm in aluminium (space grey, black, light gold, dark bronze) with the new Ceramic Shield 2 cover glass, which Apple rates 60 per cent tougher than the Series 11’s Ion-X; in polished titanium (natural, radiant gold) with sapphire; and, new this year, in polished ceramic (pearl white, night blue), also with sapphire. Apple says the aluminium cases are 100 per cent recycled aluminium, the titanium cases 100 per cent recycled and 3D-printed, and the watch is 40 per cent recycled material overall.
Apple Watch Ultra 4. Same S11, same Health Sensing System and Readiness, in the 49 mm titanium case in natural or black. The battery claims are the reason it costs twice as much: up to 50 hours in everyday use, 84 hours in Low Power Mode, 25 hours in Extended Workout mode and 45 hours in Max Extended Workout mode, with 15 minutes of charging adding up to 18 hours. It keeps the dual-frequency GPS, the 100-metre water resistance and the built-in satellite messaging that arrived on the Ultra 3, and Apple’s release repeats that Emergency SOS and Find My via satellite are included free for two years with the activation of an Ultra 3 or later. MacRumors puts the display at 3,000 nits. New bands: Trail Loop in dark umber, sand and burgundy; Alpine Loop in desert, dark olive and burgundy; and an Ocean Band in a translucent silicone in grey, kelp and black. The Hermès edition gets a Grand H titanium band with an extension mechanism designed to fit over a wetsuit.
Apple Watch SE 3. Not new. It launched in September 2025 and stays in the line-up at the same $399, which is why it appears in the price tables below but not in the what-changed sections.
watchOS 27 shipped on Tuesday 15 September as a free update and brings Siri AI, the new Apple Intelligence Siri with personal context, to the watch, along with a Siri Modular face. The Audio Intelligence features are the ones that will draw the attention. Sound Recognition alerts deaf and hard-of-hearing wearers to sirens and alarms; Shazam identifies music faster; Live Rewind shows the previous 15 seconds of a conversation as text; and Siri Recap produces a summary of a longer conversation that can be saved to the new Siri app. Apple says none of these creates or stores an audio recording, and that the raw audio is processed in a hardware-isolated Secure Exclave that is inaccessible to the operating system, apps, the user or Apple. Live Rewind and Siri Recap arrive in beta in late 2026, and require a Series 12 or Ultra 4 paired with an Apple Intelligence iPhone 16 or later, excluding the 16e. If you are buying the watch for those two features, you are buying a promise with a date on it.
What it costs here, every tier
The table sets Apple Australia’s online store prices, captured 19 September, against GadgetGuy’s launch-day list of 10 September; the two agree at every tier we could check. All prices include GST. Titanium and ceramic Series 12 models are sold only with GPS + Cellular.
| Series 12 aluminium 42 mm GPS | $649 |
|---|---|
| Series 12 aluminium 46 mm GPS | $739 (+$90 for the size) |
| Series 12 aluminium 42 mm GPS + Cellular | $799 (+$150 for cellular) |
| Series 12 aluminium 46 mm GPS + Cellular | $889 |
| Series 12 titanium 42 mm (cellular included) | $1,249 |
| Series 12 titanium 46 mm (cellular included) | $1,339 |
| Series 12 ceramic 42 mm (cellular included) | $1,599 |
| Series 12 ceramic 46 mm (cellular included) | $1,689 |
| Ultra 4, Alpine, Trail or Ocean band | $1,349 |
| Ultra 4, Titanium Milanese Loop | $1,499 (GadgetGuy) |
| SE 3 aluminium 40 mm GPS | $399 |
| SE 3 aluminium 44 mm GPS | $449 |
| SE 3 aluminium 40 mm GPS + Cellular | $489 |
Read the left-hand column as a set of surcharges. On the Series 12 the larger case is $90 in every material, cellular is $150 on aluminium and bundled above it, titanium is $450 over the equivalent cellular aluminium watch, and ceramic is $350 over titanium. The cheapest Series 12 with its own SIM, which is the configuration you need for Apple Watch For Your Kids or for leaving the phone at home, is $799. Reasoning beyond the sources: the ceramic watch at $1,689 is $340 more than an Ultra 4 with a band, and it buys a smaller battery, a lower-brightness screen and no satellite radio. It is jewellery, priced as jewellery, and Apple is not pretending otherwise.
Against last year
Last September WhistleOut recorded the launch prices of the Series 11, Ultra 3 and SE 3. Only the starting price of each line was published then, so the comparison is limited to those tiers; we have not found a reliable record of the 2025 launch price of the 46 mm or cellular aluminium Series 11 and do not claim a change for them.
| Aluminium 42 mm GPS | Series 11 $679 to Series 12 $649 (down $30) |
|---|---|
| Titanium, from | Series 11 $1,249 to Series 12 $1,249 (no change) |
| Ultra, from | Ultra 3 $1,399 to Ultra 4 $1,349 (down $50) |
| SE 3, from | $399 both years (same model) |
| Ceramic | New tier; no predecessor |
Three days ago the same company raised the price of every iPhone it sells in this country, by $100 at the bottom of the range and $900 at the top, and its leadership blamed the cost of memory chips. The watch, which MacRumors lists with 4 GB of memory and 64 GB of storage against an iPhone range that now tops out at 2 TB, is far less exposed to that market. Reasoning beyond the sources: the two price lists from the same night are consistent with each other. Apple appears to be pricing to its components, and on the watch the component that moved was the currency, not the memory.
The Australia tax, calculated
Apple’s US prices exclude sales tax; Australian prices include 10 per cent GST. The Reserve Bank’s published rate for Thursday 18 September 2026, the day the watches went on sale, is US$0.7126 to the Australian dollar; for Friday 19 September 2025, the day the Series 11 went on sale, it was US$0.6596. All of the following is our arithmetic on those inputs, rounded to the nearest dollar.
| Series 12 aluminium 42 mm GPS | US$399 converts to A$560; plus GST is A$616. Apple charges $649: about $33, or 5.4 per cent, above. Last year the same sum gave A$665 against a $679 price, a 2 per cent premium. |
|---|---|
| Series 12 titanium 42 mm | US$699 converts to A$981; plus GST is A$1,079. Apple charges $1,249: about $170, or 15.8 per cent, above. Last year: A$1,166 against $1,249, a 7 per cent premium. |
| Series 12 ceramic 42 mm | US$899 converts to A$1,262; plus GST is A$1,388. Apple charges $1,599: about $211, or 15.2 per cent, above. |
| Ultra 4 | US$799 converts to A$1,121; plus GST is A$1,233. Apple charges $1,349: about $116, or 9.4 per cent, above. Last year: A$1,332 against $1,399, a 5 per cent premium. |
| SE 3 40 mm GPS | US$249 converts to A$349; plus GST is A$384. Apple charges $399: about $15, or 3.8 per cent, above. Last year the conversion came to A$415, so the $399 SE 3 was briefly cheaper here than in the US. |
So the entry-level Series 12 carries a smaller Australia premium than any iPhone we priced this week, and the SE 3 barely carries one at all. The premium widens sharply on the metal and ceramic watches, to the same 15 per cent band the iPhone 18 Pro sits in. Our arithmetic: the 8 per cent rise in the dollar since last September should, on a straight pass-through, have taken the base Series 12 to about $616 and the Ultra 4 to about $1,233. Apple cut them to $649 and $1,349, capturing roughly two-fifths of the currency gain on the Series 12 and half of it on the Ultra 4, and all of it on the titanium watch, whose price did not move. Whether that is hedging against a currency Apple prices once a year or simply margin, we cannot say. It is the same behaviour as last year in the other direction: when the dollar falls Apple passes most of it on, and when it rises Apple passes some of it on.
The feature that is not here
The line is in both Australian press releases, near the bottom, in the same words: “Hypertension Notifications will not be initially available in Australia on Apple Watch Series 12 or Ultra 4, as additional regulatory clearances for the feature for these models is in process. Availability is expected later this year.”
To see why that matters, you need the timeline. Apple announced hypertension notifications with the Series 11 in September 2025 and switched them on in more than 150 countries at launch. Australia was not one of them; WhistleOut’s launch coverage predicted at the time that, like sleep apnoea detection before it, the feature would need to pass the TGA first. It did. MacRumors reported on 19 December that the TGA had formally listed the software on the Australian Register of Therapeutic Goods earlier that month, and Apple’s Australian newsroom announced the feature as available on 28 January 2026, on Apple Watch Series 9 and later and Ultra 2 and later. We covered that clearance, and what it does and does not tell you, in July’s piece on what your smartwatch is actually cleared to say.
The feature itself has not changed. It uses the optical heart sensor to analyse how blood vessels respond to each heartbeat, reviews the data passively over 30-day periods, and notifies the wearer if it sees consistent signs of hypertension, at which point the Health app asks for seven days of readings from a third-party cuff to take to a doctor. Apple says it was developed on data from more than 100,000 participants, validated in a clinical study of more than 2,000, and is not intended for people under 22, anyone already diagnosed with hypertension or anyone who is pregnant. Apple expected it to notify more than a million people with undiagnosed hypertension worldwide in its first year.
What has changed is the hardware underneath it. The December listing covered the sensors in the Series 9, 10 and 11 and the Ultra 2 and 3. The Series 12 and Ultra 4 have, by Apple’s own account, a redesigned optical sensor with different electrodes, photodiode layout and LEDs, and the wording of the press release — clearances “for these models” — is consistent with the regulator needing to see the same algorithm validated on the new sensor before it is switched on here. Reasoning beyond the sources: we have not seen the TGA application and cannot say what is being assessed or when it will conclude; “later this year” is Apple’s expectation, not the regulator’s commitment. Last time, the gap between Apple’s worldwide launch and the Australian switch-on was four and a half months. Apple has presumably filed earlier this time, which is why it is willing to name a year. But the practical position on 19 September is unambiguous: a Series 11 bought today will watch for hypertension, and a Series 12 bought today will not, in Australia, until further notice.
None of the other health features are affected. ECG, sleep apnoea notifications, the new Readiness score, Recovery HRV and the rest work on the new watches here from day one, because Readiness and HRV are wellness features that do not make a diagnostic claim and so do not go through the TGA at all. That distinction, between the features a regulator has looked at and the features that are simply software, was the point of our July article, and this launch is a clean example of it.
What we could not establish
Five gaps, in order of how much they matter.
We could not find any independent test of the new heart sensor. Apple’s “most accurate heart rate sensing in a wearable” rests on a study it describes but has not, as far as we can find, published in full; the 1,000-participant figure and the ranking are Apple’s. Until a lab with a chest strap and a treadmill publishes, the accuracy claim is a claim.
We could not confirm the Series 11’s 2025 launch prices for the 46 mm and cellular aluminium tiers from a source we trust, so the year-on-year table stops at the entry price of each line. Retailer listings for the Series 11 vary by more than $100 between shops and cannot be used as launch RRPs.
We could not resolve the ceramic case sizes. Apple Australia’s store lists every Series 12 at 42 mm or 46 mm; MacRumors’ buyer’s guide gives the ceramic models as 43 mm and 47 mm, a millimetre larger. We have used Apple’s labels in the table.
We could not find Australian pricing for the Hermès editions of either watch. MacRumors gives US$1,399 for the Series 12 Hermès and US$1,499 for the Ultra 4 Hermès; the local store had not surfaced them in our capture.
And we could not learn anything about the TGA process beyond Apple’s two sentences. Neither the regulator nor Apple has published a date, a scope or the reason a separate clearance is required.
What to do with this if you are buying
- If hypertension notifications are the reason you are buying, buy a Series 11 or wait. A Series 11 on run-out has the feature in Australia today; a Series 12 has a promise for later this year. If the sensor upgrade matters more to you, buy the Series 12 and accept that one feature arrives by software update.
- Buy the aluminium watch if the sums bother you. It carries a 5 per cent premium over the US price after GST; titanium and ceramic carry 15 to 16 per cent. The health sensor is identical in all three.
- Price cellular honestly. It is $150 on the Series 12, $90 on the SE 3, and then a monthly charge from your carrier. If the watch will always be within Bluetooth range of your phone, the GPS model is the same watch for less.
- Do not buy the Series 12 for Live Rewind or Siri Recap yet. They are a late-2026 beta and need an iPhone 16 or newer that is not a 16e. If your phone is older, those features do not exist for you regardless of the watch.
- Read the Ultra’s battery claims as modes, not a number. 50 hours is everyday use; 84 hours needs Low Power Mode; 45 hours of workout tracking needs Max Extended Workout mode, which turns things off. All three are Apple’s figures and none has been measured here.
- Check the trade-in. Apple’s Australian store is quoting $35 to $570 in credit for an old watch against a new one. Reasoning beyond the sources: a Series 11 is likely to hold more of its value while it is the only new-generation watch with hypertension notifications working in Australia, so if you do intend to trade one, the argument for doing it sooner is weaker than usual.
The bottom line
Apple has done something it rarely does in this country: it has cut the price of a new product against the one it replaces, and it has done it in the same week it raised the price of everything else. The reason is the exchange rate rather than generosity, and the cut is smaller than the currency alone would justify, but $649 for a watch with a genuinely new sensor is a better deal than the $679 Series 11 was a year ago. The Ultra 4 at $1,349 is the same story with bigger numbers. The regulatory footnote is the part that should decide the purchase for a specific group of buyers. Apple built the Series 12 around a heart sensor and then, in Australia, shipped it without the one heart feature a regulator has to approve. That feature will almost certainly arrive. Until it does, the older watch is the one that does more, and Apple’s own press release says so.
