National Automated Access System (NAAS)

The National Automated Access System (NAAS) is being developed by state and territory road authorities to provide industry with greater access to pre-approved networks.

The system is being developed to support a more automated approach to heavy vehicle access, reducing the reliance on manual, permit-based processes.

NAAS builds on Tasmania’s proven Heavy Vehicle Access Management System (HVAMS), which has successfully operated for nearly a decade. The system is now being scaled nationally with progressive rollouts occurring across states and territories.

NAAS works by matching any vehicle and load to the capacity of any road asset and the risk settings established by road managers. Access decisions are effectively pre-loaded, allowing the system to generate a map showing the roads available to a particular heavy vehicle based on the relevant access rules and asset information. This approach seeks to reduce the need for operators to obtain a permit and enable faster access decisions.

NAAS is designed to integrate with a range of platforms and systems, such as NHVR Go and the Victorian Heavy Vehicle Structural Assessment Permit System (HVSAPS). 

The program is overseen by a National Project Office on behalf of all states and territories.

After implementation, NAAS will become the default road access pathway for eligible low loader vehicles operating outside of the National Class 1 Load Carrying Vehicle Dimension Exemption Notice 2025 (No. 2) and National Class 1 Load Carrying Vehicle Mass Exemption Notice 2025 (No. 1).

The NHVR is supporting the NAAS Program team and jurisdictions as NAAS is progressively developed and rolled out, including identifying opportunities to integrate NAAS with NHVR Go.
