Grain Harvest Management Scheme
The NSW Grain Harvest Management Scheme (GHMS) promotes the safe and productive movement of grain. It is designed to decrease harvest risk, protect roads and to increase productivity and efficiency for the movement of grain. The GHMS also seeks to provide a productivity benefit for growers and a higher degree of visibility to road managers of the use of their road assets.
How to operate under the GHMS
Under the GHMS, eligible heavy vehicles may exceed regulated total mass limits by up to 5% when delivering the following grains to participating grain receivers in participating council areas:
- Cereals that are wheat, barley, rice, oats, triticale, sorghum, maize or millets
- Oilseeds that are canola, sunflowers, monola or safflower
- Pulses that are chickpeas, faba beans, lupins, mung beans, field peas, soybeans, vetch, or lentils.
There is no enrolment process or administration fee for eligible heavy vehicles to operate under the GHMS. All eligible heavy vehicles operating under the GHMS New South Wales Class 3 GHMS Mass Exemption (Notice) 2022 (GHMS Notice) must comply with the conditions of the GHMS Notice, approved participating council areas and approved routes for that vehicle type. Please refer to the GHMS map and approved routes.
To support delivery to a participating grain receiver operators should know their truck code and mass limit from the list of eligible heavy vehicles.
GHMS map and approved routes
The enforceable GHMS map provides details of the approved and excluded participating council areas and routes and conditions of access for eligible heavy vehicles operating under the GHMS. The map also shows participating grain receiver sites.
Eligible vehicles must operate under the conditions of the New South Wales Class 3 GHMS Mass Exemption (Notice) 2022 and must only travel on approved routes for that vehicle type and/or as per any Council consent condition as contained in the maps and approved routes list:
- Eligible General Access Vehicles operating under the scheme may operate on all state classified roads and approved local and regional roads in participating council areas. This includes rigid trucks, truck and dog combinations and single trailer combinations not exceeding 19 metres long, and 19 metre B-doubles not exceeding 52.5 tonnes.
- Eligible Restricted Access Vehicles (RAVs) operating under the scheme may only operate on state classified roads (roads managed by Transport for NSW) and local and regional roads in participating council areas that are approved for that type of RAV. Approved RAV routes are shown on the interactive RAV map.
Eligible heavy vehicles operating under the scheme must not operate where prohibited by a load limit specified for a road, bridge or causeway by a sign or notice.
Note: The published maps and lists of routes are the legally enforceable network in NSW.
Compliance and enforcement
Exceeding scheme mass limits at participating grain receivers
Details of overloaded vehicles will be reported to the National Heavy Vehicle Regulator (NHVR) by participating grain receivers and analysed for compliance management and enforcement. Additional measures may be put in place by receivers to maintain the low incidence of industry overloading.
Penalties may be imposed on one or more of the parties in the chain of responsibility for the load in the following circumstances:
- Breaches of scheme operating conditions
- Breaches of scheme axle mass limits and total mass limits
- Non-compliance with approved routes.
Vehicles or combinations found to be breaching scheme operating conditions will be assessed against the regulated mass limits and penalties will be applied accordingly.
On road enforcement
Vehicles and combinations participating in the scheme will be subject to on-road inspections by NHVR and local council inspectors and police officers.
2022/27 Participating councils
Local councils may decide to participate in the scheme for the complete period or for specific time periods and may also specify access conditions.

2022/27 Participating Grain Receivers
Become a Participating Grain Receiver
To sign up to the Scheme as a Participating Grain Receiver send through the following information to firstname.lastname@example.org:
- Signed Undertaking form
- Your weighbridge certificate(s)
- GPS coordinates of your receival sites.
Once we have all of this information, we will publish your receival sites on the map and notify you to commence reporting.
Participating Grain Receiver Reporting
As a Participating Grain Receiver (PGR) you must report on all vehicle deliveries to the National Heavy Vehicle Regulator. The data reported will be used to:
- Monitor compliance with the NSW GHMS's mass limits
- Assist in planning future improvements to the NSW GHMS
As a PGR you must also have a process in operation for managing overloaded deliveries to meet chain of responsibility obligations and discourage the transport of illegal overloads on the road network. More information can be found on the National Heavy Vehicle Regulator (NHVR) Chain of Responsibility webpage.
PGR reporting requirements
As a PGR you must report on all vehicle deliveries, including overload vehicle deliveries, irrespective of scheme or rejection to Transport for NSW using the approved template. GHMS Reporting Template.
Each column in the template must be filled out and the Truck Type Code you use must be codes from the NSW Grain Harvest Management Scheme Eligible Vehicle configurations and Allowable Weight Limits chart.
When you email in your monthly reporting:
- The reporting file on all vehicle deliveries must be titled: [name of receiver] - [name of site] - [date range of data] - All deliveries Example: ABCGrain - Narrabri - 01.01.22 - 31.01.22 - All deliveries
- The reporting file on overloaded deliveries must be titled: [name of receiver] - [name of site] -[date range of data] - Overloads Example: ABCGrain - Narrabri - 01.01.22 - 31.01.22 - Overloads
The reports must be emailed to: NHVR.DataScience@nhvr.gov.au
When your harvest receivals have finished email: NHVR.DataScience@nhvr.gov.au to notify that there will be no more reporting for the season.
If you have any questions as a Participating Grain Receiver email: email@example.com

NSW GHMS Harvest Reports
The GHMS Harvest Reports show the continuing importance of the NSW GHMS in enabling efficiency in the movement of grain while at the same time maintaining road safety and reducing the impact on the road network through reducing the total number of heavy vehicle trips.
GHMS Harvest Reports are developed from the harvest data provided by Participating Grain Receivers.
