The HMMS was developed to assist the grain industry with the difficulties experienced loading grain from a paddock. This is not a concessional loading scheme.

The Scheme commences each year between the first day of October and finishes on the last day of February. 

HMMS Order and Business Rules

The Harvest Mass Management Scheme Order 2019, must be carried in the vehicle and produced to Main Roads or WA Police upon request.

Grain Receivers and transport operators must comply with the HMMS Business Rules (PDF).

Scheme Registration - Grain Receivers

Grain receivers wishing to offer HMMS must be registered and approved to join the scheme using the Grain Receiver Registration forms (Word document).

Participation is voluntary; however, non-participating grain receiver operations will not be able to offer the HMMS allowances to transport operators delivering grain to their receival depots.
