How EV adoption insulates Australia against oil supply shocks
16.03.2026 - 03:52
Mandala’s latest research finds that the adoption of electric vehicles is helping to insulate Australians from the oil supply shocks. This analysis looks at the contribution of Australia’s electric vehicle fleet to our petrol reserves, as well as the savings in fuel costs for Australian households.
Australia currently holds 36 days of petrol, 34 days of diesel, and 32 days of jet fuel in reserve. This fuel supply remains anchored to one of the world’s least stable regions, and therefore every reduction in Middle East dependence is important for Australia.
Our modelling found that our current adoption of electric vehicles (EVs), including hybrid and fully battery, has started to materially increase Australia’s fuel independence, with passenger EVs already saving the equivalent of 1.2 days of petrol use.
Policies such as the Fringe Benefits Tax exemption for EVs and the New Vehicle Efficiency Standard have helped increase EV uptake, but Australia still lags behind global leaders significantly. If Australia matched Norway's EV penetration rate, the highest in the world, our petrol reserve cover would grow by 11 days, a 30 per cent increase on the current 36-day reserve.
Our analysis also found that if the elevated fuel prices from the Middle East conflict persist for a year, the average two petrol-vehicle household could face more than $700 in additional annual fuel costs, a rise of at least 23 per cent on pre-conflict fuel bills.

Shaping the Australian banking system for a changing economy
Mandala’s latest research, prepared for the Commonwealth Bank of Australia, finds that Australian banking has been transformed beyond recognition by technology, globalisation, and regulatory change. However, policy has not kept pace. Major banks now face a shrinking revenue base while providing a growing suite of collective goods including regional branches, ATM networks, and payment infrastructure, that comparable financial institutions are not required to provide. The report finds that declining profitability and an uneven regulatory playing field amid rising geopolitical uncertainty place Australia's financial resilience at risk. It recommends three principles for policymakers to shape Australia’s banking system to best serve our national interest. First, consider system-wide impacts of policy settings. Second, apply the same obligations to firms conducting the same activities with the same risk. Third, assess how overseas firms operating in critical parts of the financial system would behave in a crisis.

The Fragmentation Tax
Australian retailers operate across a patchwork of inconsistent state and territory regulations that, left unchecked, will cost the economy $26 billion and households $9.4 billion over the next decade. Commissioned by the Australian Retail Council, this Mandala report finds that regulatory fragmentation in retail - Australia's second-largest employer, generating $649 billion in economic activity annually - is compounding the country's productivity crisis at the worst possible time. The report identifies specific issues in transport and logistics, and packaging and waste as priority areas for reform, where harmonisation alone would inject up to $1.65 billion into the economy over 10 years. It recommends the Federal Government use its National Competition Policy framework to drive reform - including a $260 million increase to the National Productivity Fund, a new National Harmonisation Council, and a mandate that Regulatory Impact Statements explicitly quantify fragmentation risks.

Reforming Victoria's Windfall Gains Tax
Victoria's Windfall Gains Tax (WGT), introduced in July 2023, has compounded a decade of new and increased property taxes that have made Melbourne the most costly major city in Australia for development. Commissioned by the Property Council Victoria, this Mandala report finds that developer taxes and charges now account for 18% of total costs on Melbourne developments - double the rate of Sydney - and that the average WGT liability pushes project returns below the viability threshold. The analysis estimates that removing the WGT could unlock $1.4 billion in additional annual investment, support 2,700 jobs and deliver the equivalent of 3,100 new homes per year by 2030. The report also presents a suite of targeted reforms across financial relief, predictability, and policy alignment that would restore investor confidence while balancing the government's revenue objectives.
