Do I need an Oversize Overmass Permit?
You may need to apply for a class 1 Oversize Overmass (OSOM) permit if your OSOM combination does not comply with a mass, dimension or operating requirements set out in a gazette notice.
To apply for an Oversize Overmass permit:
- for travel within ACT/SA/Tas/Vic - apply through the NHVR Portal. Please note that VicRoads has updated pilot requirements in Victoria. For more information read the Guide for pilot requirements in Victoria information sheet (PDF, 221KB).
- for travel within NSW - apply through the NHVR Portal or apply to Roads and Maritime Services for state-controlled roads and directly to individual councils for local government roads.
- for travel within Qld - apply directly to the Department of Transport and Main Roads.
- for cross-border travel - apply through the NHVR Portal. Note: The NHVR processes all cross-border applications except for travel within the Northern Territory and Western Australia. For these jurisdictions, apply directly to the relevant state or territory road transport authority.
Note: Operators should check that their vehicle complies with the schedules and conditions in the relevant gazette notice as the permit relevant to this application will reference these same conditions.
