Tesla's FSD (Supervised) v13.2.9 has been detected on Australian vehicles running software update 2026.8.3.10 β and it wasn't mentioned anywhere in the official release notes. Teslascope flagged the feature on a Model 3 Performance (2024) in New South Wales early Friday morning, confirming the autonomous driving stack is alive and active Down Under on this build.
The officially documented change in 2026.8.3.10 is Comfort Braking β a smoother stop algorithm that feathers brake pressure near the end of a deceleration event, whether you're driving manually or under Autopilot. FSD v13.2.9 appearing alongside it is the undocumented part. Tesla didn't call it out in the release notes, but Teslascope's detection system picked it up as a new feature on the Australian build.
For context, Australia was one of the first right-hand-drive markets globally to receive FSD (Supervised), with the initial rollout beginning in August 2025 for HW4-equipped vehicles. FSD v13.2.9 itself isn't new to the region β it's been observed there since at least early March 2026 β but its presence in this specific build confirms the version is continuing to propagate through the fleet as Tesla pushes 2026.8.3.10 more broadly. As of April 2026, new Australian vehicle orders can only access FSD through a subscription (AUD$149/month for HW4 owners), following the end of outright purchase availability on March 31.
The evidence here is strong: Teslascope logged it independently across two separate feature detections on the same build, on the same vehicle, within seconds of each other. That's not a fluke. Australian owners on HW4 hardware who haven't yet received 2026.8.3.10 should watch their update queue β and check whether FSD is active in their vehicle's feature list once it lands.
