AgForce General President Grant Maudsley said a groundswell of anger was building over the proposed changes with the community protests co-inciding with five Parliamentary committee hearings being held in regional Queensland over three days this week.

"These laws are the worst of both worlds. The Palaszczuk Government will make it harder for farmers to grow food and they won't deliver the best environmental outcomes either," Mr Maudsley said.

"At a time when global demand for our great food and fibre is at all-time high, these laws will shut down new agricultural development opportunities in Queensland.

"Farmers just want fair and workable laws to grow more food, create jobs and look after their environment without being strangled in red tape. It's pretty simple - if farmers can't feed their own families, they can't feed yours."

There will be a free barbecue lunch and protest at the Cloncurry Shire Hall on Wednesday March 28 starting at noon ahead of the public hearing starting at 1.30pm

 Mr Maudsley urged anyone concerned about Queensland's economic future and farmers' ability to keep producing food to come along and show their support at the rallies this week.

"We're calling on the Queensland Parliament to reject these flawed laws and instead work with those most affected by the changes to come up with a long-lasting solution that delivers good outcomes for both agriculture and the environment," he said.
