From 1 August 2026, the amended Heavy Vehicle National Law replaces the National Heavy Vehicle Accreditation Scheme (NHVAS) with the new Heavy Vehicle Accreditation (HVA) scheme, built on a documented Safety Management System. NHVAS stops accepting new applicants that day; existing accreditations stay valid, and operators have up to three years to transition to HVA.
Key facts at a glance

What is changing on 1 August 2026?
The amended Heavy Vehicle National Law commences on 1 August 2026 across NSW, Victoria, Queensland, South Australia, Tasmania and the ACT (WA and the NT sit outside the HVNL). Ahead of commencement, the NHVR and NTC jointly released the supporting statutory instruments — the Safety Management System Standard, the Ministerial Guidelines for Heavy Vehicle Accreditation, the National Audit Standard and the Ministerial Standard for Alternative Compliance Hours — shifting the regime from prescriptive compliance toward risk-based safety-management outcomes. The reform also modernises fatigue and mass management, with mass limits lifting by up to a tonne and combination lengths increasing to 20 metres in some cases.
What is replacing NHVAS?
NHVAS is being progressively replaced by the new HVA scheme. The two run side by side during the transition, but an operator can only hold accreditation in one at a time. From 1 August 2026, NHVAS stops accepting new applicants — anyone applying for the first time goes into HVA instead. Existing NHVAS holders are not switched over automatically: accreditation stays valid until expiry, with up to three years, the maximum accreditation period, to move across to HVA.
What is the difference between GSA and ACA?
HVA has two pathways. General Safety Accreditation (GSA) is the new baseline all accredited operators must hold, requiring a documented, auditable Safety Management System covering how the operator identifies, controls and improves safety risk. Alternative Compliance Accreditation (ACA) is the advanced pathway, building on GSA to grant modular operational concessions tied to demonstrated safety capability.
What is a Safety Management System under the HVA scheme?
The standards for GSA sit in the ministerially approved Safety Management System Standard 2026, covering several broad categories including how safety systems are designed, documented and maintained. GSA becomes the destination for many operators currently holding NHVAS Mass Management and Maintenance accreditation, replacing fixed per-module checklists with one integrated, evidence-based system.
Do I need to do anything if I already hold NHVAS accreditation?
Not immediately. Existing NHVAS accreditations remain valid until they expire, and operators have up to three years to transition into HVA. There is no need to rush before 1 August 2026, but it is worth using the transition window to understand what a documented SMS looks like under the new standard.
How does this connect to Chain of Responsibility?
The HVNL primary duty and the Chain of Responsibility parties — consignors, consignees, packers, loaders, unloaders, loading managers, operators, prime contractors, schedulers and employers — are unchanged by this reform. Each party still carries a non-delegable duty to ensure safety so far as reasonably practicable. What changes is the practical evidence for that duty: a documented Safety Management System is now the formal mechanism HVA-accredited operators use to show they manage transport-activity risk, and it is a useful best-practice model for any chain party wanting to demonstrate the same, even where SMS accreditation is not required of their role.
Which businesses are affected?
Current NHVAS holders, particularly those with Mass Management or Maintenance accreditation, are most directly affected, since GSA becomes the pathway many transition into. Any operator seeking accreditation for the first time from 1 August 2026 applies into HVA rather than NHVAS. More broadly, any business that consigns, packs, loads or schedules heavy vehicle transport in NSW, VIC, QLD, SA, TAS or ACT sits within the Chain of Responsibility and carries the underlying safety duty, whether or not it holds formal accreditation.
How should CoR parties prepare?
Preparation at this stage is about awareness, not paperwork. Chain parties should confirm whether their business or transport partners hold NHVAS accreditation and understand the transition timeframe that applies. Everyone in the chain benefits from understanding what the primary duty requires and how a documented safety-management approach evidences it. Nationally recognised training is the most reliable way to build that understanding ahead of 1 August 2026.
| Feature | NHVAS | HVA scheme (GSA / ACA) |
|---|---|---|
| New applicants accepted | No — closed from 1 August 2026 | Yes, from 1 August 2026 |
| Existing accreditation holders | Remain valid until expiry | Transition within up to 3 years |
| Core requirement | Module-based compliance (e.g. Mass Management, Maintenance) | Documented, auditable Safety Management System |
| Baseline pathway | Not applicable | General Safety Accreditation (GSA) |
| Advanced pathway | Not applicable | Alternative Compliance Accreditation (ACA), builds on GSA |
| Governing standard | Existing NHVAS business rules | Safety Management System Standard 2026, National Audit Standard |
| Regulatory approach | Prescriptive compliance | Risk-based safety-management outcomes |
| Jurisdictions | NSW, VIC, QLD, SA, TAS, ACT | NSW, VIC, QLD, SA, TAS, ACT |
Key takeaway: the Safety Management System is now the backbone of heavy vehicle accreditation. A documented, auditable system for identifying and controlling safety risk is how operators evidence compliance under HVA — and it is fast becoming the benchmark chain parties across the industry are expected to understand, even where they are not accreditation holders themselves.
Frequently asked questions
What is replacing NHVAS on 1 August 2026?
From 1 August 2026 NHVAS is progressively replaced by the new Heavy Vehicle Accreditation (HVA) scheme, built around a documented Safety Management System. NHVAS stops accepting new applicants that day, and existing accreditation holders have up to three years to transition to HVA.
When does the amended HVNL commence?
The amended Heavy Vehicle National Law commences on 1 August 2026.
Which states and territories are covered by the change?
The amended HVNL and the HVA scheme apply in New South Wales, Victoria, Queensland, South Australia, Tasmania and the Australian Capital Territory. Western Australia and the Northern Territory are not part of the HVNL.
Can I still apply for NHVAS after 1 August 2026?
No. NHVAS stops accepting new applicants from 1 August 2026. Anyone seeking heavy vehicle accreditation for the first time after that date applies into the HVA scheme instead.
How long do I have to transition from NHVAS to HVA?
Existing NHVAS accreditations remain valid until their expiry date. Operators have up to three years, the maximum accreditation period, to transition across to the HVA scheme.
What is General Safety Accreditation (GSA)?
General Safety Accreditation is the new baseline all HVA-accredited operators must hold. It requires a documented, working and auditable Safety Management System covering safety risk identification, control and continuous improvement.
What is Alternative Compliance Accreditation (ACA)?
Alternative Compliance Accreditation is the advanced HVA pathway. It builds on General Safety Accreditation and grants modular operational concessions tied to demonstrated, advanced safety capability.
Does this change who is in the Chain of Responsibility?
No. The primary duty and the parties in the Chain of Responsibility, including consignors, consignees, loaders, schedulers, operators and employers, are unchanged. What changes is that a documented Safety Management System is now the formal way HVA-accredited operators evidence how they manage that duty.
