Australian consumers are bracing for steeper grocery bills, after a confluence of geopolitical tensions in the Middle East, spiking oil prices and global supply chain disruptions has created a ‘perfect storm’ that is raising costs across every segment of the domestic food supply network. In a stark public warning issued this week, the Australian Food and Grocery Council (AFGC) confirmed that the ongoing United States-Iran conflict has created persistent instability in global energy markets, keeping crude oil and fuel prices at elevated levels that have not receded despite widespread market expectations for stabilization.\n\nAFGC chief executive Colm Maguire explained that the ripple effects of the Middle East crisis have touched every node of the food and grocery supply chain, from agricultural production to retail shelves. ‘This is a fundamental shift in the cost of doing business. From the fertilisers used on our farms to the fuel in the trucks that transport goods and the energy powering our factories, every single link in the chain is more expensive,’ Maguire told NewsWire in an interview.\n\nThe industry body, which represents more than 200 food, beverage and grocery manufacturers across Australia, is currently conducting a granular, product-by-product assessment to quantify how the ongoing oil crisis will translate to higher shelf prices for consumers. ‘There is no simple answer to how much prices will rise, it is a very complex scenario,’ Maguire noted. ‘The inputs we are dealing with range from fertiliser and oil through to transport, energy production and plastic packaging costs. We will be facing this elevated cost environment for a considerable period of time.’\n\nUnlike broad-based pricing adjustments that can be rolled out quickly, Maguire said supermarkets cannot simply apply a uniform percentage price hike across all products to offset the oil price shock. Instead, individual producers and suppliers must calculate the unique impact of the crisis on their own operating margins before passing adjusted costs through to retailers and end consumers.\n\nThe sharp rise in fuel costs was triggered in March, when activity through the Strait of Hormuz – the critical global chokepoint through which roughly 20% of the world’s daily crude oil consumption passes – was effectively blocked, creating massive bottlenecks that cut global supply volumes significantly. Before the Middle East conflict escalated in January, benchmark crude traded at approximately $US56 ($A78) per barrel. In the months since, prices have fluctuated between $US100 and $US110 ($A138 to $A152) per barrel, with every $10 per barrel increase translating to an extra 10 cents per litre for Australian motorists and freight operators.\n\nWhile higher transport costs are the most obvious impact for most consumers, Maguire emphasized that the cost pressures extend far beyond moving goods across the country. ‘It is complex even for us. From a consumer perspective or even a leadership perspective, it is hard to understand the sheer number of products and processes that oil and petrochemicals touch,’ he said. ‘Everything from the wrapping that goes around the bread to the bottles that hold milk through to tissue boxes and nappies sees broad impacts. Early on, the focus was all on fuel and petrol prices, but the flow-on effects for oil-dependent packaging – which is incredibly important in the grocery industry – are an inevitable added cost.’\n\nFor months, Australian manufacturers, suppliers and retailers absorbed as much of these increased costs as possible to shield consumers already grappling with a widespread cost-of-living crisis, but Maguire warned that the cumulative pressure has become too great to absorb, meaning price hikes are now unavoidable for consumers.\n\nThe strain is already visible across Australia’s agricultural sector, where producer margins are being stretched to breaking point. A separate new report from Rabobank finds that Australian dairy producers are entering the 2026/27 production season with a ‘limited margin for error’ as compounding input costs continue to squeeze profitability.\n\nRaboResearch senior dairy analyst Michael Harvey said that while seasonal growing conditions have improved across most major dairy regions, these modest gains are not enough to offset the persistent upward pressure on production costs. ‘Pressure is building across the broader value chain,’ Harvey explained. ‘Processors are facing higher packaging costs, driven by a spike in global resin prices directly linked to the global oil supply crisis. At the same time, energy and processing costs have increased, as have distribution costs, reflecting higher energy and freight prices, further adding to the cost of getting products to market.’\n\nDairy producers have already begun implementing price hikes to cope with the rising pressure. In late April, Norco chief executive Michael Hampson confirmed that the farmer-owned dairy cooperative would increase milk prices by five cents per litre to cover elevated freight costs. ‘This increase is expected to add about 30c per week to the average household grocery bill, but it will deliver an additional $1m per month back to struggling farmers,’ Hampson said. The announcement came as industry groups warn that broader milk price surges are on the horizon.\n\nMajor national retailers and processors have already adjusted producer payments in response to the crisis. Woolworths announced it would increase payments to farmers supplying its private-label Farmers Own Brand by 10 cents per litre, supporting around 20 small-scale producers. Lactalis, Australia’s largest dairy company which owns popular brands including Ice, Oak and Pauls, will add an extra five cents per litre to payments for more than 800 farm suppliers starting May 1. The industry peak body Australian Dairy Farmers is calling for a permanent 20% across-the-board increase in milk prices, arguing that after suppliers, retailers and government take their respective cuts, the increase would leave producers with enough additional revenue to cover rising costs.\n\nHarvey confirmed that Australian consumers have already started seeing higher milk prices at the checkout due to these compounding input cost pressures. ‘A renewed cycle of food price inflation, including for dairy, would further test consumer resilience,’ he said. ‘Households are already adjusting their shopping behaviour, increasingly trading down to lower-cost private-label products and prioritizing value over well-known brands.’\n\nHarvey added that price increases beyond the farm gate have left processors with little remaining capacity to absorb additional cost shocks, increasing the risk of broader food inflation that could put upward pressure on interest rates in the coming months.
