Above the base price the levy adds to the freight rate. Below it, the levy is negative and the rate comes down. Shown on a $7.00/km rate with a 30% fuel component.

| Item | What it means | Figure |
|---|---|---|
| Diesel price | Previous week's average Sydney diesel Terminal Gate Price, as published by the Australian Institute of Petroleum. | $2.63/L |
| Base price | The fixed benchmark: Sydney diesel TGP on 1 February 2026. | $1.62/L |
| Fuel component | The part of the standard freight rate attributed to fuel, using an industry average. | 30% |
| Weekly levy | Applied to the standard rate. It can be positive, zero or negative. | 18.70% |
This week: ($2.63 ÷ $1.62 − 1) × 30% = 18.70%. On $7.00/km that adds $7.00 × 18.70% = $1.31/km, a rate of $8.31/km.
Add one line to freight quotes, carrier agreements and manure supply contracts. Edit the address to the page you are referencing.
Manure is heavy and low in value per tonne, and it often travels a long way. On many loads the freight costs as much as the product, so a move in diesel changes the delivered price far more than it does for most cargo.
Supply contracts can run for months. With no agreed mechanism someone carries the fuel risk. A published levy lets carriers quote without a fuel contingency, and buyers avoid paying up front for a rise that may not happen.
The levy applies to freight only. The agreed ex-farm product price does not change.
Longer contracts. Agree supply and freight without guessing where diesel will be in six months.
Easier quote comparison. Every carrier quotes a standard rate and the same levy applies to each.
A clear record. Buyers, sellers, carriers and brokers use one method, with the calculation shown each week.
The 2026 Road Transport Contractual Chain Order showed the value of a standing method for responding to fuel-price movements along a contractual chain. Its fuel-cost recovery obligations stopped applying from 7 June 2026, though the Order itself remains in effect.
The levy gives you a documented method and a record of each weekly calculation. It does not by itself establish compliance. Each party remains responsible for its own obligations.
General information only. Seek advice on your own arrangements.
No. It applies only to freight. The agreed ex-farm price of the manure does not change.
Each Monday at 9:00 am. Loads delivered in different weeks can carry different levies under the same contract. The levy for the week the load is delivered applies, and the buyer's final price adjusts to that week's levy.
Sydney TGP is a single, independently published diesel price. A standard fuel component lets every contract use the same method. Earlier weeks in the history used 33%.
The levy adjusts only for diesel price movements. Any other change to the standard rate is handled under your contract.
No. The levy is a reference method. Each carrier applies it through their own pricing page in the carrier portal on the PureManure website, and the levy is then included automatically in the freight quoted for products.
