Farmers take to CBD to protest tree laws

More than 300 farmers have gathered outside Parliament House in Brisbane to protest against the Palaszczuk government's vegetation management laws.

Carrying signs reading, "No Farmers, No Food" and "Fair Laws For Farmers", the march started at Queens Park and the chanting crowd passed a handful of environmental activists along George St who were holding signs in favour of the laws.

March organiser AgForce president Grant Maudsley said the protest was timed to coincide with the Royal Brisbane Show, which starts on Friday, because of the number of farmers and their families visiting Brisbane.

"We've got farmers in Brisbane for Ekka so it was logical for us to protest now because we are all here," Mr Maudsley said.

AgForce claims the new laws will make it harder for farmers to work the land, mean fewer jobs and increase the price of produce.

"We haven't asked for a roll-back of major laws, we just want to grow some crops, a bit of high value agriculture and grow our businesses."

He said the Katter Party had shown their support but he was still waiting to hear from independent MPs Rob Pyne and Billy Gordon to support blocking the bill although he was confident that at least Gordon was onboard.

"They (Katter Party) are on side. They're fine, they're with us," Mr Maudsley said.

"We need Billy Gordon. The feedback from his community is that there is no one telling him he should pass the laws as they exist."
