Tesla's biggest software update for Australian and New Zealand owners in nearly a year is now reaching a fourth wave of vehicles. FSD (Supervised) v14.3.3, delivered as part of the 2026.16.6 software release, is expanding its local rollout — and the changelog is substantial. Here's everything HW4 owners Down Under need to know.
1. This is the biggest FSD leap for AU/NZ since September 2025
Before 2026.16.6, local vehicles had been running FSD v13 since its regional debut in September 2025. The jump to v14.3.3 is the first major generational upgrade for the market — not an incremental patch. According to confirmed reports, the official @TeslaAUNZ and @Tesla_AI accounts simultaneously announced the launch on June 19, 2026, marking the start of a phased rollout that is now reaching its fourth batch of owners.
2. Hardware 4 only — older cars are excluded
FSD v14.3.3 Down Under is exclusive to vehicles equipped with Hardware 4 (HW4/AI4). In practical terms, that means current-generation Model Y (Juniper) and Model 3 (Highland) vehicles. If your Tesla shipped with an older hardware stack, this update will not appear in your queue regardless of your subscription status.
3. The AI architecture was rebuilt from the ground up
This isn't just a tuning update. Tesla rewrote the AI compiler and runtime using MLIR, delivering a claimed 20% faster reaction time. The neural network vision encoder was also upgraded to improve understanding in rare and low-visibility situations, strengthen 3D geometry recognition, and expand traffic sign coverage — all particularly relevant for Australian road conditions and signage that differs from the US fleet's training data.
4. Driving behavior gets noticeably smarter
The official release notes list several concrete behavioral improvements: reduced unnecessary lane biasing and minor tailgating, more decisive parking spot selection, better responses to emergency vehicles and school buses, improved handling of small animals, and stronger performance at complex intersections with compound traffic lights and curved approaches. Tesla also notes improved handling of temporary system degradations — the car now maintains control and recovers automatically rather than forcing a driver takeover.
5. New Speed Profiles and Arrival Options change how you use FSD daily
Two new UI-level features ship with this update. Speed Profiles let FSD determine pace based on a mix of your driver profile, the posted speed limit, and surrounding traffic — the right scroll wheel now adjusts this setting rather than a precise speed offset. A new "SLOTH" profile adds an ultra-conservative option below "CHILL." Arrival Options (Carpark, Indoor Carpark, Street, Driveway, Pull Over) allow "Robotaxi-style" drop-off preferences that are saved per destination, with the navigation pin adjusting to match your selection.
6. You can now track your intervention-free distance
The Self-Driving App will now display the distance you've traveled in FSD without an intervention, along with your longest intervention-free streak. Owners can also select an intervention reason directly on the main screen after taking over, helping Tesla's fleet training. These stats are accessible under Controls > Self-Driving. It's a small but meaningful addition for owners who want to benchmark their own FSD experience over time.
7. Smart Summon is not included in the AU/NZ release
One notable gap: Smart Summon — the feature that lets your car navigate a car park and drive itself to you — does not appear in the local release notes and was reported as non-functional on at least one tested vehicle. It's unclear whether this is a regulatory limitation or a staged rollout decision. Owners should not expect Smart Summon to be available with this update.
Subscription pricing for AU/NZ
As of April 1, 2026, FSD (Supervised) in Australia and New Zealand is available on a subscription basis only. The outright purchase option has ended. Current pricing is AUD $149/month in Australia and NZD $159/month in New Zealand. If you're on HW4 and haven't yet subscribed, the 4th batch rollout means the feature is now accessible to a significantly larger share of the eligible fleet.
For owners who haven't received the update yet, the phased rollout is still in progress — check Software > Software Update in your Tesla app or vehicle touchscreen. Given this is already the fourth batch, broader availability across the HW4 fleet in both countries should follow shortly.
