Fonterra Australia said it is looking at formulating a "co-operative solution" for its Aussie suppliers, who at present work outside the co-op's structure.
Rene Dedoncker, who heads the co-op's Australian operation, said the Aussie business was becoming stronger as its product mix was rebalanced.
"Our plants, including our recently reopened Stanhope cheese plant, are operating efficiently," he said. Stanhope was closed in 2014 after a fire.
Dedoncker said the co-op was continuing to grow its Australian business and would soon announce investments that will increase processing capacity by 500 million litres.
"We're also exploring ways that we can work more closely with our suppliers, including whether there is a co-operative solution for our Australian suppliers," he said.
Fonterra, at its results presentation last month, said it planned to invest $100 million expanding across the Tasman.
