The rollout of FSD (Supervised) version 14.3.3 commenced last week, with the first eligible Tesla vehicles receiving the update on June 19. The software is available for Australian-delivered Model Y and Model 3 vehicles equipped with the company's Hardware 4 (HW4) camera system, which serves as the foundation for Tesla's latest driver-assistance technologies.
The update marks another step in Tesla's broader effort to expand the capabilities of its autonomous driving software outside the United States. While FSD (Supervised) first arrived in Australia in September 2025, the latest release introduces several new features and refinements aimed at improving both safety and usability.
Notably, the Australian version differs slightly from the v14.3.3 software launched in the United States earlier this year, reflecting local driving conditions and regulatory requirements.
The update arrives at a time when Tesla's presence in the Australian market remains particularly strong. The company's Model Y electric SUV recently became the country's best-selling new vehicle across all fuel categories during May 2026, surpassing long-time market leaders such as the Ford Ranger, Toyota HiLux and Toyota RAV4.
Both the Model Y and Model 3 currently sold in Australia feature HW4 hardware and can access FSD (Supervised) through Tesla's subscription service, following the company's shift away from offering the technology solely as a one-time purchase.
A key component of the new software is what Tesla describes as an "upgraded Reinforcement Learning (RL) stage of training the FSD neural network", which the company says delivers "improvements in a wide variety of driving scenarios".
The enhancements are expected to reduce the frequency with which drivers need to intervene while the system is operating. To help owners track performance, Tesla has also introduced a feature that displays the longest intervention-free driving period achieved during FSD use.
Tesla says it has further improved the system's neural network encoder, allowing the vehicle to better interpret traffic signs and react more quickly to changing road conditions.
According to the company, the upgrade delivers a claimed 20 per cent improvement in reaction time, potentially enabling smoother responses to traffic events and hazards.
Additional refinements include better recognition of emergency vehicles, more intelligent handling of roadworks and complex intersections, fewer unnecessary lane changes, and improved detection and interpretation of smaller animals near the roadway.
One of the most noticeable additions for drivers is the introduction of a new "Sloth" Speed Profile.
The new mode prioritises lower speeds and "more conservative lane selection" than Tesla's existing Chill mode. It joins the existing Standard and Hurry profiles, giving drivers greater flexibility in choosing how assertively the vehicle behaves in traffic.
Tesla says the behavioural differences between the various Speed Profiles have also been made more distinct, allowing drivers to better tailor the system to their preferences.
The update includes several interface and naming changes as well. The company's long-running "Navigate on Autopilot" feature has been renamed "Navigate on Autosteer", while the onboard FSD Computer is now referred to as the AI Computer.
Tesla has also simplified the process of activating FSD. Brake Confirm is now disabled by default at the start of a journey, meaning drivers no longer need to press and release the brake pedal before engaging the system.
Another major enhancement comes at the end of a trip. New Arrival Options allow drivers to determine how the vehicle completes the final stage of a journey rather than requiring manual control near the destination.
The available options include "Car Park", "Indoor Car Park", "Street Driveway" and "Pull Over", with the vehicle adjusting its final destination point based on where the user places a navigation pin.
Drivers can also initiate an FSD session directly from the touchscreen while parked or during a journey, while updated centre-screen graphics make it easier to access Speed Profiles and Arrival Options.
The latest Australian rollout comes as Tesla continues to pursue broader autonomous mobility ambitions globally.
While FSD (Supervised) still requires active driver monitoring and intervention when necessary, Tesla has already launched its fully driverless Robotaxi service in the United States. Interest in the company's autonomous future was further fuelled last week after two examples of Tesla's purpose-built Cybercab were spotted in New Zealand.
Responding to speculation, Tesla Australia confirmed to CarExpert that the vehicles were undergoing cold-weather testing in New Zealand, a key step in validating autonomous systems under varying environmental conditions.
The latest FSD update highlights Tesla's continued investment in artificial intelligence and autonomous driving technology, as the automaker seeks to bring increasingly sophisticated self-driving capabilities to customers around the world while moving closer to its long-term vision of fully autonomous transportation.
