Impacts of heavy vehicle reform

Study report
Heavy vehicle transport is vital to Australia’s economy, but road freight physical productivity has stalled for more than a decade.
This final report sets out the PC’s findings, recommendations and modelling. Better road access for high productivity and heavy zero emissions vehicles – supported by reforms such as automated access approvals, clearer planning rules for charging infrastructure, and updated curfew and licensing settings – could help restart productivity growth and reduce emissions.
This report was sent to government on 30 June 2026 and publicly released on 14 August 2026.

- Heavy vehicle transport plays an important role in the Australian economy, but productivity growth in the road freight sector has stalled for over a decade.
- Advances in technology and vehicle design provide opportunities to re start productivity growth and improve emissions outcomes.
- The recent fuel supply disruption has only strengthened the case for reform to unlock higher productivity and lower emissions vehicles.
- High productivity vehicles, heavy zero emissions vehicles (HZEVs) and automated permits can support productivity uplift if deployed well. These opportunities will only be realised if all tiers of government collaborate to remove regulatory and other barriers to innovation and investment.
- Governments are working together on new national approaches, while individual jurisdictions are pursuing reforms that demonstrate how new technologies can improve vehicle access and how regulations can be updated to recognise electric vehicle charging as an emerging form of land use.
- However, more can be done to accelerate this work. The largest potential productivity benefits will arise from reforms that increase access to Australia’s road network for high productivity vehicles.
- The largest potential productivity benefits will arise from reforms that increase access to Australia’s road network for high productivity vehicles.
- Increasing General Mass Limits (indicative of general increases to road access) would boost long-run GDP by about 0.03-0.10% ($900 million to $2.7 billion based on 2024-25 GDP), depending on the level of ambition.
- Implementing the National Automated Access System (NAAS) would boost long-run GDP by about 0.02-0.05% ($600 million to $1.3 billion based on 2024-25 GDP).
- Reforms that work towards ‘as of right’ access – reducing the time and costs associated with applying for a permit for pre approved vehicles driving on pre approved networks – should be prioritised, as should reforms that make it easier to get high productivity and low emissions vehicles on the road.
- Additional funding for the road infrastructure assessments needed to support informed decision-making about access and a focus on building local government capacity will help ensure that the NAAS roll-out does not fall further behind.
- Adjusting noise-based curfews to exempt HZEVs, ensuring planning rules are suited to HZEV charging, facilitating private investment in HZEV charging in heavy vehicle rest areas and improving information to guide charging site selection will assist uptake of HZEVs.
- National driver competency reforms to improve safety have been agreed, though implementation across jurisdictions will largely occur between 2026 and 2028.
- Implementing the National Heavy Vehicle Driver Competency Framework would boost long-run GDP by about 0.004-0.015% ($100 to $400 million based on 2024-25 GDP).
