Almost half of all new cars sold in Australia between April and June 2026 were electric, plug-in hybrid, or hybrid vehicles, according to the Australian Automobile Association's EV Index. The figure signals a structural shift in a market that has long been one of the most combustion-dependent in the world: when the AAA's EV Index began recording data in 2022, internal combustion engine (ICE) cars — vehicles powered solely by petrol or diesel — accounted for nine out of every ten vehicles sold (The Guardian).

Battery electric vehicles (BEVs), which run entirely on battery power, reached a record 21.03% market share in the April–June quarter. Plug-in hybrids, which combine a battery with a petrol engine and can be recharged from the grid, hit a record 10.58%. Add in conventional hybrids — which use a petrol engine assisted by an electric motor but cannot be plugged in — and electrified powertrains approached 50% of the total new-car market. Toyota led hybrid sales over the quarter, according to the AAA (AAA EV Index).

The pace of the BEV surge was dramatic. Battery electric vehicle sales more than doubled from 34,435 units in the first quarter of 2026 to 69,414 in the second, per the AAA, which described the Q2 increase as the largest-ever quarterly rise for electric vehicles. First-quarter BEV sales had themselves been a record — the first time Australian quarterly BEV sales exceeded 30,000 units, with nearly half (46%) sold in March alone. March 2026 BEV sales of 15,865 were more than double January's 7,420, and monthly BEV market share rose 73.6% over the same period, from 8.71% to 15.12% (AAA).

On the other side of the ledger, ICE vehicles fell from 64.23% market share in Q1 to 50.84% in Q2. The AAA recorded both as records: the lowest-ever ICE share and the biggest-ever quarterly drop (The Guardian).

The broader context here is one where fuel affordability and geopolitics converged on consumer behaviour. Fuel prices in Australia peaked in March 2026 amid Middle East instability affecting key supply routes. On 30 March 2026, the federal government announced a fuel excise reduction — a cut to the tax motorists pay on each litre of petrol — to offset the impact of the ongoing crisis. Those reductions were due to end on 2 August 2026, with fuel prices on track to top $2 a litre again (The Guardian).

The timing is worth examining closely. The sharpest monthly jump in BEV sales occurred in March, precisely when fuel prices peaked. Q1 overall was weak for total volume: 281,103 new light vehicles were sold, the second-lowest quarterly figure since the AAA EV Index began in 2023 (AAA). Yet within that constrained market, electrified powertrains were capturing share at an accelerating rate. By Q2, that share-gain dynamic had translated into absolute volume growth, with BEV sales more than doubling quarter-on-quarter even as the broader market remained soft.

What the data does not settle is how much of the shift is structural versus crisis-driven. If the excise cut functioned as a price ceiling on petrol, its expiry on 2 August re-introduces the fuel-cost pressure that coincided with the initial surge in BEV demand. Whether that produces a further acceleration in electrified adoption or a reversion toward ICE as total market volume recovers will be the key data point in the next AAA release.

What is unambiguous is the trajectory over the four years the EV Index has been running. ICE share has moved from roughly 90% to just under 51% in a single quarter. Plug-in hybrid adoption, often treated as a transitional technology bridging the gap between petrol and full electric, has set its own records alongside pure-electric growth. And conventional hybrids, while still growing, have been eclipsed by full-electric volume for the first time. The Australian market, long characterised by high ICE penetration and limited model availability, is converging toward electrified majorities at a pace that few projections from 2022 would have captured.
