About the National Automated Access System
In late mid-2022, we consulted with other state jurisdictions and the National Heavy Vehicle Regulator (NHVR) to investigate and analyse different heavy vehicle access management systems in use across Australia.
We concluded the Tasmanian Heavy Vehicle Access Management System (HVAMS) presents the best solution to meet the needs of the Queensland Government, road managers and Queensland's Class 1 heavy vehicle industry operators.
The Tasmanian HVAMS was developed by the Tasmanian Department of State Growth (TDSG) in consultation with Tasmanian road managers, heavy vehicle operators, industry bodies and the National Heavy Vehicle Regulator (NHVR), to introduce HVAMS to the Oversize Overmass industry in 2016. Since this time, and due to its success, TDSG have expanded HVAMS to include Special Purpose Vehicles including mobile cranes.
In August 2022, all Australian Transport Ministers agreed to establish a new National Automated Access System (NAAS) for heavy vehicles within 3 years. This will provide a single seamless national system to automate decision making on at least 90% of current permit requests for all heavy vehicles within 5 years.
In July 2023, the Senior Officers of all Australian jurisdictions agreed that the NAAS will be based on HVAMS and informed by the HVAMS version 3.0 implementation projects underway in Tasmania, New South Wales and Queensland at the time.
Benefits of the NAAS
The NAAS helps road managers make better access decisions and provides the heavy vehicle industry with access certainty through a generated tailored map for their individual vehicle with associated access conditions.
Industry operators can use the map to:
- visually identify a viable route for a journey
- confirm any pilot and escort requirements, special travel conditions over bridges
- confirm other important information like time curfews and road closures.
This map is the legal access map, and their journey can start immediately.
Since the NAAS precursor, HVAMS, was introduced into Tasmania, it has been shown to significantly reduce administrative costs and permit related workloads for industry and road managers by automating the access decision making process.
NAAS has many innovative solutions and benefits including:
- an access vehicle interface that collects vehicle parameters which are used by analysis tools within the system for access decision making
- modules for assessing heavy vehicle access requests against structures and roads
- a mapping interface to display the available network and conditions matched to the user's heavy vehicle, including access conditions (e.g. structure crossing conditions, road closures, pilot and escort requirements, curfews).

How access and permits will differ
Access under the current Multi-State Class 1 Load Carrying Vehicle Mass Exemption Notice 2023 will remain unchanged.
Access by Period Permit and Single Trip Permit will be replaced by access via a dynamic Notice enabling the National Automated Access System (NAAS), or a NHVR Permit.
Most Period Permit vehicles and some of the Single Trip permit vehicles will move to access through the NAAS, hence the NAAS Notice row below is shown larger.
| Current access regime | New access regime |
|---|---|
| Single Trip Permit | NHVR Permit |
| Period Permit | NAAS Notice |
| Class 1 Load Carrying Vehicle Mass Exemption Notice (59.5t) | Class Load Carrying Vehicle Mass Exemption Notice (59.5t) |
The National Automated Access System (NAAS) replaces the Conditions of Operations Database
Under the new access regime, all Class 1 vehicle access conditions will be displayed in the NAAS and the Conditions of Operations Database will be eventually deactivated.
Current entries in the Conditions of Operation Database will be validated and its contents transferred to the NAAS.
When vehicle details are entered into the NAAS:
- a map will be produced for that individual vehicle to show roads and bridges available for that vehicle
- details of all relevant access conditions required, and restrictions are provided.
Conditions will be specific to vehicle configuration inputs such as pilot-escort arrangements, along with other more general conditions such as curfew times and road closures. Before starting a journey, all routes with any conditions or restrictions will be shown to the operator to choose the best route available.
Road managers will maintain access conditions of operation within the NAAS as part of the new access regime.
