Woolworths fuel levy on suppliers nearly triples since Iran war as diesel costs climb

Freight surcharge rises to almost 20 per cent in metro areas and 50 per cent regionally, with experts warning consumers may foot the bill

Woolworths has increased the fuel levy it charges food and grocery suppliers through its logistics network to almost triple pre-war levels, reflecting sharp rises in diesel costs since the Iran war, with experts warning the increase is likely to be passed on to consumers at the check-out.

Woolworths has lifted the fuel levy surcharge applied to its freight network, affecting more than 1,000 grocery producers including Sanitarium, PepsiCo, Ingham's and Arnott's. The levy for metro areas rose from 17.47 per cent to 19.88 per cent, while regional areas saw an increase from 44.20 per cent to 50.30 per cent.

Before the Iran war, the metro levy was 7.28 per cent, rising to 12.47 per cent within weeks of the conflict. The regional levy has jumped by more than 172 per cent since March, when it stood at 18.44 per cent.

Primary Connect, Woolworths' logistics arm, transports goods from suppliers to distribution centres and stores, and the company says it manages the network to support its transport partners. A Woolworths spokesperson said the company increased its review of the fuel levy to twice monthly in March to reflect the challenges transport providers face.

Supply chain experts say the increase is a common response to rising diesel prices. University of Sydney professor Rico Merkert noted that fuel levies are widely used in freight markets to manage price volatility and that recovering additional operating costs is reasonable when diesel costs rise sharply. However, he cautioned that freight is only one component of the final shelf price, so consumers may not see a direct or proportional increase.

Others are less optimistic. Medo Pournader, senior lecturer at the University of Melbourne, predicted that consumers and suppliers will get the worst end of the deal. Ben Fahimnia, a University of Sydney professor, warned that pushing costs onto suppliers is not sustainable, saying "someone ultimately has to pay, and, at these fuel levy rates, that will be Australian consumers at the check-out."

Rising fuel prices have been a significant factor in Australia's inflation, which reached 4 per cent in August, and transport was a contributor.

Analysis

Why This Matters

  • The fuel levy increase affects the cost structure of major food and grocery suppliers, potentially leading to higher prices on supermarket shelves across Australia.
  • With inflation already at 4 per cent, further cost pressures could feed into broader consumer prices, impacting household budgets.
  • The move reflects how geopolitical events, such as the Iran war, ripple through supply chains to everyday retail costs.

Background

The Iran war, which began in early 2026, triggered a surge in global oil and diesel prices. Fuel levies are a standard mechanism in freight and retail logistics to pass on fuel price fluctuations without renegotiating contracts each time. Woolworths, one of Australia's largest supermarket chains, uses Primary Connect to manage freight for over 1,000 suppliers. The levy is reviewed regularly, with the company increasing the frequency to twice monthly since March to respond to ongoing fuel price challenges.

Key Perspectives

Woolworths: The company says it is committed to supporting its transport partners, many of whom are independent operators, and that the increased levy is necessary to keep trucks on the road and shelves stocked. It frames the rise as a response to challenges transport providers still face.

Suppliers: Manufacturers are absorbing some costs initially but have limited capacity to do so. Professor Fahimnia argues that pushing costs back is unsustainable and that ultimately the burden will shift to consumers.

Consumers: Experts like Pournader predict consumers will bear the brunt, though Merkert suggests the impact may be muted because freight is only one element of the final price. The exact pass-through remains uncertain.

What to Watch

  • Whether other major retailers, such as Coles or Aldi, follow suit with similar levy increases.
  • Diesel price trends: if fuel costs stabilise or fall, the levy may be adjusted downward in future reviews.
  • Upcoming inflation data: whether the August 4 per cent figure rises further, indicating broader price pressures.
  • Supplier negotiations: how suppliers respond, potentially seeking to renegotiate terms or pass costs on to consumers.
