The NSW Farmers Association will urge the consumer watchdog to increase transparency from major dairy companies at an ACCC inquiry on the NSW mid north coast.
The association will encourage the consumer watchdog to "lift the veil" on the impact of $1 per litre milk as well as pricing mechanisms and contract terms at the public forum 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.
"Even measures that are supposed to even out the playing field, like collective bargaining groups, need to be critically analysed and improved."
Last year 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.
