Farmers will push for greater transparency from major dairy companies at an inquiry into the industry being held on the NSW mid-north coast.
The NSW Farmers' Association will urge the consumer watchdog to "lift the veil" on the impact of $1 per litre milk as well as pricing mechanisms and contract terms at an ACCC inquiry in Taree on Tuesday.
"Farmers can feel powerless against the big companies but this is our chance to raise our concerns," association dairy committee chair Erika Chesworth said in a statement on Monday.
"Even measures that are supposed to even out the playing field, like collective bargaining groups, need to be critically analysed and improved."
The ACCC industry-wide inquiry was initiated in October.
Earlier in 2016 the country's biggest dairy producers, Murray Goulburn and New Zealand-based Fonterra, announced retrospective cuts to the price they pay farmers partly prompted by major supermarkets selling milk at $1 a litre.
Ms Chesworth has advocated following the example of overseas nations.
"In other countries, such as Ireland, measures including annual retrospective price reporting takes the mystery out of the supply chain and improves the business relationship between companies and farmers," she said.
