Minister Byrne will return to the position after moving from the Police and Emergency Services portfolio. He moved to the Police portfolio in December after being sworn in as the Agriculture Minister when Labor won the Queensland state election in 2015.

The Queensland Farmers' Federation (QFF) president Stuart Armitage welcomed the reappointment of Minister Byrne and thanked the Premier for ensuring the agriculture portfolio had an experienced Minister with and a track record of listening and working constructively with the sector.

"Growing Queensland's $17 billion plus agricultural sector depends on the right government support and policy settings, and we look forward to working with Minister Byrne to realise this," Mr Armitage said.

Agricultural lobby group AgForce urged Minister Byrne to be a strong advocate for agriculture both in the community and in the Cabinet room.

AgForce general president Grant Maudsley said global demand for Queensland's high quality food and fibre is growing rapidly, and can continue to grow strongly - but only with the right policy settings from governments.

"AgForce established a good working relationship with Bill Byrne when he was previously Agriculture Minister, and we acknowledge both his and Leanne Donaldson's efforts in helping to secure stamp duty exemptions for farmers passing down the family farm to the next generation," Mr Maudsley said.

"We urge Minister Byrne to champion the needs of people in the bush both publicly and behind the closed doors of Cabinet to ensure agriculture continues to prosper into the future," he said.

AgForce said Minister Byrne would need to hit the ground running to bed down live issues in his new portfolio.

"It's vital the Minister provides clear messages about the need to maintain a high standard of biosecurity and to ensure its importance is recognised across the community," Maudsley said.

"We would also urge the Minister to ensure funding for wild dog fencing gets out on the ground as quickly as possible, and that grants announced in the Budget to help farmers access financial advice are rolled out as a priority," he said.

"With welcome rain in many parts of Queensland and good commodity prices in many sectors, there is a real momentum in agriculture that can be maintained if governments at all levels throw their support behind an industry that is the backbone of so many of our regional communities."

Byrne replaces Leanne Donaldson who resigned on 3 November due to unpaid property rates and car registration.
