Oversize Overmass permit

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:

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.

Pilot and escort requirements

Please note: State and territory road transport authorities regulate all aspects of piloting/escorting, including who may operate as a pilot/escort vehicle driver and when they are required to accompany a load.
