Diesel, Freight, and the Cost Picture Heading Into Winter 2026

By Yield Australia Market Intelligence ·

The cost picture for Victorian vegetable growers has shifted noticeably over the past six weeks. Diesel has come off its peak, but freight rates and packaging costs are stickier. Here's our read on where things sit in mid-May 2026 and what to expect through winter.

Diesel — Off the Highs but Still Elevated

National average wholesale diesel pricing has softened by ~6-8 cents per litre over the past month, with retail bowser prices in Melbourne now sitting in the $1.92-$2.04/L range for diesel. That's still well above the five-year average, but the trend over the past quarter has been mildly positive for growers.

What's driving it:

  • A relatively well-supplied global oil market through Q2 2026
  • Some easing of geopolitical risk premiums versus the elevated levels of late 2025
  • The Australian dollar holding in the high US 60s, providing some protection against further imported-fuel cost increases

Risk to watch: Any renewed flare-up of Middle East tensions, or a meaningful weakening of the AUD, could quickly push diesel back into the $2.10+ territory we saw in February.

Freight — The Stickier Problem

Freight costs from growing regions into Melbourne Markets have not followed diesel down. Truck operators are passing through diesel relief slowly, and other cost pressures (driver wages, vehicle running costs, compliance) remain elevated.

For Werribee South to Melbourne Markets, typical freight rates remain 12-18% above where they sat 12-18 months ago. Peak-season surcharges (think school holidays, public holiday weekends) can push that gap to 25%+ on premium delivery windows.

Packaging and Consumables

Cardboard, plastic, and labelling costs have stabilised — most growers we talk to report flat-to-slightly-down pricing on packaging contracts renewed in Q1 2026. Pallet hire is the exception, with continued upward drift in CHEP and LOSCAM hire rates.

What This Means for Margin Planning

If you're putting together your winter production budget, here's what we'd plug in:

  • Diesel — Budget on $2.00/L delivered for the next three months, with upside risk if geopolitics shifts
  • Freight — No relief expected. Assume current rates hold through winter
  • Fertiliser — Still elevated. Lock in pricing where you can (see our recent post on the Iran crisis and fertiliser supply)
  • Labour — Award rate increases from July 1 add another 3-4% to direct labour costs

Where to Find Margin

The cost picture won't get materially better in the short term. Where we see growers protecting margins is through:

  1. Yield improvement — Spending more per hectare on better seedlings, better soil prep, and tighter nutrition pays off many times over compared to cutting corners
  2. Logistics consolidation — Sharing freight runs with neighbours, building backloads, and shifting delivery timing where possible
  3. Premium positioning — Quality, presentation, and consistency continue to command meaningful price premiums at Melbourne Markets

Our Farm Planning Toolkit includes calculators for cost-per-tray-equivalent, freight optimisation, and seasonal cash-flow modelling — useful tools when the cost picture is this dynamic.
