Weekly freight wrap: HVNL is live, fuel taxes jump today, and Kenworth hits 90,000

What happened on 1 August 2026?

The amended Heavy Vehicle National Law (HVNL) commenced on 1 August 2026. It is the first major rewrite since the law began in 2014, passed by Queensland Parliament on 18 November 2025, with the final standards and guidelines approved by ministers in May 2026.

The headline changes for operators: a new Heavy Vehicle Accreditation (HVA) scheme replaces NHVAS. Every accredited operator must now run a documented, auditable Safety Management System (SMS). The new scheme has two tiers: General Safety Accreditation (GSA) as the baseline, and Alternative Compliance Accreditation (ACA) for operators with advanced safety systems who need operational flexibility.

• One audit per accreditation period — but more thorough, testing whether systems are Present, Suitable, Operating and Effective (PSOE). Findings are graded minor or major, and digital evidence like telematics and electronic records carry more weight.
• A new fatigue standard with new outer limits, sitting under the Alternative Compliance Framework. Existing BFM/AFM accreditations transition over time.
• An expanded "Unfit to Drive" duty now covers any reason a driver cannot safely operate — illness, injury, medication, mental health, drugs, alcohol — and applies to every vehicle 4.5 tonnes and up. Drivers are legally empowered to stop driving if unfit.
• Productivity wins: General Mass Limits (GML) rise to align with current Concessional Mass Limits (CML), maximum vehicle length for general access rises from 19 metres to 20 metres, and Euro VI concessions expand to include road trains.

What happens to my NHVAS accreditation now?

Your existing NHVAS accreditation remains valid until its expiry date. You have up to three years from expiry to transition to the new HVA scheme, or you can transition sooner if you choose. From 1 August 2026, NHVAS stops accepting new applicants.

Two practical points: check your NHVAS expiry date now so you know your runway, and if it expires within the next 24 months, start planning your transition immediately — auditors will be in heavy demand through late 2026.

What is the fuel cost change on 3 August 2026?

From today, diesel costs for truckies jump another 32 cents per litre. The Federal Government is lifting the Road User Charge (RUC) from 16.4 cents per litre to 32.4 cents per litre, while the Fuel Excise at the bowser increases from 36.6 cents per litre to 52.6 cents per litre.

National average diesel prices have already climbed above $2 per litre for the first time since May, increasing more than 40 cents per litre this month as tensions in the Middle East escalate and global fuel markets react.

NatRoad and Road Freight NSW are both urging the Federal Government to drop the RUC back to zero, arguing it is the only lever available to prevent another global fuel shock from hitting operators and consumers.

What happens to my fuel tax credits?

Fuel tax credit rates for diesel used in heavy vehicles travelling on public roads drop from 20.6 cents per litre to 20.2 cents per litre from 3 August 2026. The full "all other business uses" rate rises to 52.6 cents per litre.

If you claim fuel tax credits, check your BAS reporting uses the rate that applied on the date you acquired the fuel. The ATO fuel tax credit calculator is the safest way to get the number right.

What else happened this week?

Three more items worth your attention:

• Kenworth delivered its 90,000th Australian-made truck to McColls Transport on 22 July, celebrated at PACCAR's Bayswater facility in Melbourne. The milestone underscores the ongoing strength of Australian heavy vehicle manufacturing.
• NatRoad's pre-Budget submission highlights the sector's financial stress: less than 3% margins, one of the highest insolvency rates in Australia, and compliance burdens from HVNL reform stacked on top of insurance, wages, parts and maintenance cost increases.
• The NHVR's Heavy Vehicle Safety Initiative (HVSI) Round 11 closed for applications on 16 March 2026. Successful projects will be announced in August 2026, with a focus on emerging technologies and digital safety tools.

What to do this week

• If you operate in NSW, VIC, QLD, SA, TAS or ACT, confirm your business understands the new HVNL requirements — especially the SMS and Unfit to Drive duties.
• Check your NHVAS expiry date and start your transition timeline if it expires within 24 months.
• Update your fuel cost forecasts: the combined RUC + excise increase adds roughly 32 cents per litre at the pump from today.
• Verify your fuel tax credit claims use the correct post-3 August rate.
• If you run on paper diaries or EWDs, read the NHVR's guidance on the new work diary rules that align with the HVNL amendments.
