Federal ministers are discussing possible road-user charges for electric vehicles (EVs) as fuel excise revenue falls due to more Australians switching from petrol and diesel cars.

Treasurer Jim Chalmers said he is working with states and territories to discuss the future of road-user charging for EVs, ahead of a government productivity roundtable next week.

Tanya Plibersek, a federal frontbencher, called the idea “sensible” to ensure funding for road construction and maintenance as EV adoption increases.

Revenue from fuel excise, traditionally used for road upkeep, is expected to drop as EV numbers rise.

🧠 Food for thought

1️⃣ Road funding challenges were predicted well before mass EV adoption

The current debate over EV road taxes isn’t a reactive policy scramble. It reflects challenges transport economists identified years ago.

Back in 2018, when Australia had only 476 public charging stations nationwide and EVs represented just 0.1% of new car sales, experts were already highlighting the inevitable decline in fuel excise revenue as a major policy challenge1.

The 2018 analysis specifically proposed “a road user pricing system, where both petrol and electric vehicles would be charged based on kilometers driven” as the solution to address revenue shortfalls from declining petrol use1.

This early recognition suggests the current federal discussions represent planned policy transition rather than crisis management. It has given Australia time to design more comprehensive systems.

The government’s current approach of working with states and territories on “future road-user charging” aligns with solutions policy experts mapped out when EV adoption was still minimal1.

2️⃣ Constitutional complexity creates implementation hurdles for state-level EV charges

Victoria’s failed attempt to impose a 2-cent per kilometer EV charge demonstrates the legal challenges states face when trying to fill fuel excise gaps independently.

The High Court’s 2023 ruling overturning Victoria’s EV charge reveals constitutional constraints that weren’t apparent when the policy was designed. This has created uncertainty for other states considering similar measures.

New Zealand’s successful road-user charge system for EVs provides a working model. However, Australia’s federal structure creates additional jurisdictional layers that complicate direct policy transfer.
