Agribusiness is a price-taker on most outputs and a price-taker on most inputs. That leaves a narrow band of genuinely controllable margin — and knowing exactly where it sits matters more here than in almost any other sector.
What moved in 2026
Fuel excise returned to 53.7c/L on 3 August 2026, after moving to 20.6c in April and 36.6c in July. The restored rate is above the 52.6c pre-crisis baseline because excise is indexed.
Fuel tax credits are the critical variable. For agricultural operations:
- Off-road use — machinery, pumping, generators, on-farm activity — generally attracts a credit at or near the full excise rate
- Heavy vehicles on public roads attract excise less the road user charge
- Light vehicles on public roads generally attract no credit
The credit rate moves with the excise rate. It changed four times in five months. If you have not recalculated your claim since 3 August, you are almost certainly claiming the wrong amount — in one direction or the other.
Interest. Cash rate at 4.35% after three consecutive rises to May 2026. Finance costs across small business are up 36.3% since March 2020. For an industry that runs on seasonal finance, equipment debt and land debt, this is frequently the largest single cost movement.
Freight repriced with fuel, twice, affecting both inbound inputs and outbound product.
Labour. Award rates +4.75%, minimum wage +5.97% to $26.44/hr from 1 July 2026, superannuation at 12%, and Payday Super moving contributions to every pay run — which matters disproportionately in an industry with concentrated seasonal payrolls.
Where the controllable margin sits
You do not control commodity prices, weather, or global input markets. You do control these.
Fuel tax credit accuracy. The most commonly under-claimed item in Australian agriculture. Apportionment between on-road, off-road and auxiliary use requires records, and the rates changed repeatedly this year. This is often four figures a year of genuine recovery for a mid-sized operation.
Finance structure. With rates at current levels, the difference between a well-structured facility and an accumulated mix of equipment finance, overdraft and trade credit can be several percentage points across the whole debt position. Review annually, not when something breaks.
Input purchasing timing and terms. Volume consolidation, payment terms traded against price, forward positions where the market allows.

Machinery cost per hour. Depreciation, finance, maintenance, fuel and operator, divided by actual operating hours. Most operations have never calculated it, and it determines whether contracting out beats owning.
Electricity. Small business received the largest DMO cut of any customer class from 1 July 2026 — up to 14%. Pumping and shed loads are material.
The cash cycle problem
Agribusiness has one of the most extreme cash cycles in the economy: inputs paid at planting, revenue received at sale, with months in between and weather risk throughout.
Two things made it harder this year.
Payday Super, from 1 July 2026, moved superannuation from quarterly to every pay run. For seasonal operations with concentrated payroll periods, this pulls a meaningful cash outflow forward into exactly the wrong part of the cycle.
Interest at current levels raises the cost of carrying that gap.
Arrange facilities before you need them. 34% of Australian SMEs sourced non-bank lending in the past twelve months and 92% have used or would consider it. Terms negotiated from a position of strength are consistently better than terms negotiated in a poor season.
What to do this month
- Recalculate fuel tax credits against the 3 August excise change. Check your on-road/off-road apportionment records support the claim.
- Review the whole debt position, not facility by facility.
- Calculate machinery cost per operating hour for your major plant.
- Check your electricity offer against the July DMO change.
- Model the Payday Super cash impact across your seasonal payroll pattern, not on an annual average.
