Dairy farmers' rising costs and the war in Iran may lead to higher supermarket milk prices

Supermarket milk prices are predicted to rise due to increased dairy farmer costs, exacerbated by the war in Iran. Major dairy companies like Lactalis and Norco are increasing payments to farmers, while Woolworths and Coles are reviewing their pricing structures. Rising costs for fuel, grain, fertilizer, and packaging are impacting farmers and processors, leading to calls for permanent price increases on supermarket shelves.
