Grain Harvest Management Scheme
The NSW Grain Harvest Management Scheme (GHMS) promotes the safe and productive movement of grain. It is designed to decrease this risk, protect roads and to increase productivity and efficiency. 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.
2016/21 Grain Harvest Management Scheme (GHMS)
Following the success of the 2014/16 GHMS, the Scheme will continue to operate from 1 July 2016 to 30 June 2021 to improve the productivity and efficiency of the grain transport task.
Under the scheme, 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.
New South Wales Class 3 GHMS Mass Exemption (Notice) 2016
The New South Wales Class 3 GHMS Exemption Notice 2014 expired on 30 June 2016.
Roads and Maritime has worked with Transport for NSW, the Grain Harvest Management Scheme Consultative Committee and the National Heavy Vehicle Regulator to amend and extend this Notice. The New South Wales Class 3 GHMS Exemption (Notice) 2016, commenced on 1 July 2016.
The following changes have been made:
- The Notice has been extended for 5 years with an expiry date of 30 June 2021
- Schedule 1 has been removed and replaced with a link to the legally enforceable Scheme network
- 2 additional vehicle codes (reflecting 2 configurations) have been included in the eligible vehicle list:
- Code 4 — 5 axle Semitrailer
- Code 49 - 3 axle truck with 5 axle dog trailer and 4 axle dog trailer.
2016/21 Participating councils and grain receivers
Local councils may decide to participate in the scheme for the complete period or for specific time periods and may also specify access conditions.
Participating grain receivers (PGRs) must provide data on all vehicle deliveries, including overloaded deliveries, to Roads and Maritime for compliance and enforcement action and operate in accordance with the New South Wales Class 3 GHMS Mass Exemption (Notice) 2016. Please note that not all sites of a PGR may be eligible to receive grain at GHMS masses. To be eligible the site must be either on a state road or on a road or in an area approved by a participating council.
Participating councils, conditions of access, and excluded areas and routes
Participating grain receivers
The enforceable GHMS map provides details of the approved and excluded areas/routes and conditions of access for eligible heavy vehicles operating under the New South Wales Class 3 GHMS Mass Exemption (Notice) 2016.
Note: The published maps are the legally enforceable network in NSW.
The interactive Grain Harvest Management Scheme (GHMS) map shows approved routes and restrictions as an overlay on top of Google maps. Roads and Maritime has no responsibility for, and does not guarantee the accuracy of, the underlying Google maps.
Roads and Maritime strives to be accurate in showing the GHMS approved routes and restrictions, however, there may be errors and omissions caused by Google maps being incorrect or out of date. Roads and Maritime is not responsible for errors or omissions.
Travel conditions which apply to an approved route or area for a restricted access vehicle must be observed. This map should be read in conjunction with the list of participating councils and Participating Grain Receivers which are frequently updated to align with the map.
Where can I travel?
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 Roads and Maritime) 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.
2016/21 Scheme eligible vehicles
The following types of heavy vehicles are eligible to participate in the scheme:

Transporting grain across borders
The NSW Scheme’s mass limits only apply within NSW Borders. Different mass limits apply in other states unless the vehicle or combination is eligible for Concessional Mass Limits (CML) or Higher Mass Limits (HML).
In Victoria, there is no mass exemption scheme for grain transport and the General Mass Limits apply unless the vehicle or combination is eligible for CML or HML.
For more information on Victorian mass limits, please contact Vicroads.
In Queensland mass limits up to 7.5% above General Mass Limits apply to vehicles registered in the Queensland GHMS, subject to compliance with scheme requirements. The Queensland GHMS masses are not permitted in NSW.
For more information on the Queensland scheme, please contact Agforce Queensland.
Compliance and enforcement
Exceeding scheme mass limits at participating grain receivers
Details of overloaded vehicles will be reported to Roads and Maritime 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 Roads and Maritime and local council inspectors and police officers.
Roads and Maritime NSW Grain Harvest Management Scheme Harvest Period Reports
The NSW Grain Harvest Management Scheme Snapshot report - July to December 2017 is based on data provided to Roads and Maritime by Participating Grain Receivers during that period.
The NSW Grain Harvest Management Scheme July 2016 – June 2017 Harvest Period Report has been redesigned to provide more information and insights for stakeholders and partners.
The report shows the continuing importance of the NSW Grain Harvest Management Scheme in providing 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.

Review of the 2013/14 GHMS
The NSW Government trialled the GHMS from October 2013 to May 2014 in response to industry needs for improved productivity and efficiency in the grain transport task. The GHMS was designed to:
- Facilitate the movement of grain from farms to grain receivers during the peak harvest season
- Improve the productivity of and efficiency in the grain transport task
- Protect road and bridge infrastructure
- Promote the safe movement of grain across the state
- Recognise industry's higher productivity needs
- Support the competitiveness of the NSW grain industry in national and international markets.
An independent review of the 2013-14 scheme found it was well received and should continue for future harvests. A summary of the review, prepared by Transport for NSW, is available to download.
