Tesla Model 3 and Model Y Dominate Australia's Used EV Market as Sales Surge 138% in March 2026

Australia's used electric vehicle market just posted one of its biggest monthly leaps on record — and Tesla is sitting squarely at the top. The Model 3 and Model Y were the two bestselling used EVs in the country during March 2026, according to market data shared by Tesla analyst Sawyer Merritt, as cost-conscious Australians increasingly abandon petrol and diesel in favour of cheaper-to-run alternatives.

Why Australians Are Buying Used Teslas Right Now

The 138% month-over-month jump isn't a fluke — it reflects a structural shift in how Australians think about transport costs. With petrol prices remaining a persistent household pressure point, the total-cost-of-ownership argument for EVs is landing harder than ever. And when buyers look at the used EV market, they consistently land on Tesla.

The reason is straightforward: the Model 3 and Model Y have the largest installed base of any EVs in Australia, which means the most used inventory, the most owner reviews, and the most established service and charging infrastructure. Buying a used Tesla in Australia carries far less uncertainty than buying a used EV from a brand with a smaller footprint.

The supply picture, however, is tightening fast. Available used EV stock dropped 38% in March, leaving just 28.6 days of national supply. That's a seller's market — and prices are already responding. According to MotorMetrics' live inventory analysis, used Model Y prices rose more than 6% in just the final two weeks of March. Used Model 3 prices moved upward as well.

New Car Demand Reinforces the Pattern

The used market dominance doesn't exist in isolation. In the new BEV segment, the Model Y led all battery-electric vehicles in Australia with 2,818 deliveries in March 2026, and the Model 3 added another 667 sales. When a car tops both the new and used sales charts simultaneously, it signals genuine, broad-based consumer preference — not just a promotional blip.

Auction house Pickles reported 60% growth in used EV sales compared to February, a data point that underscores how quickly institutional channels are responding to demand. As more Australians enter the EV market through the used channel, Tesla's early-mover advantage in right-hand-drive markets like Australia continues to compound.

🔭 The BASENOR Take

📰 Deep Dive

What makes March 2026 notable isn't just the headline number — it's the speed of the shift. A 138% month-over-month increase in used EV sales is the kind of data point that typically takes a full quarter to develop. The fact that it happened in a single month suggests a demand trigger: likely a combination of fuel price pressure, increased consumer awareness of EV running costs, and a growing pool of 2–4 year old Teslas entering the used market from early adopters upgrading to newer models.

The 28.6-day supply figure is particularly telling. Industry convention typically treats 45–60 days of supply as a balanced market. At 28.6 days, Australia's used EV market is operating well below that threshold — meaning dealers and private sellers hold significant pricing power. The 6% price increase for used Model Y units in just the last two weeks of March is a direct consequence of that imbalance.

For Tesla specifically, the dual dominance in new and used markets creates a virtuous cycle. Strong new car sales today become the used car inventory of 2027 and 2028. Australia's Supercharger network — now one of the most developed in the Asia-Pacific region — reduces range anxiety for used buyers who might otherwise hesitate. And Tesla's over-the-air update model means a three-year-old Model 3 or Model Y often runs software that's nearly as current as a new delivery, removing a key objection that plagues used ICE vehicle purchases.

The Pickles auction data adds another dimension: institutional buyers — fleet operators, rental companies, and dealers — are entering the used EV space at scale. A 60% jump in auction-house EV sales in a single month isn't driven by individual consumers alone. It suggests commercial operators are beginning to treat used Teslas as a viable fleet asset, which could sustain elevated demand well beyond a single month's fuel-price spike.
