You may need a permit before you can transport an oversized load. Depending on the situation, we may need to move, raise or shield powerlines, provide a road escort or even temporarily switch off power to keep everybody safe.
Depending on the route and the size of your load, we may need to help you by moving, raising, or shielding powerlines or by providing a road escort.

To apply for a permit, you must first register with us as a customer. You will need to provide your company name, contact details and ABN.
