Primary Industries Minister Tim Mulherin announced on Tuesday his new strategy aimed at trebling the value of the State's farm output by 2020, including leveraging more private sector investment in research, the sale of old facilities, and the DPI taking over the running of Queensland's agricultural colleges.

But Shadow Primary Industries Minister Mike Horan said the Coalition had proposed the revamp and change two years ago, but it was then rejected by Labor.

"Now it's Minister Mulherin's 'Fresh Approach' so I welcome this direct lift of our policy," Mr Horan said.

"The Coalition will also provide local boards with agricultural and independent expertise to make the colleges a real success and a thriving part of rural education, research, development and field days."

Mr Horan said the devil would be in the detail of the Government's approach, and the industry needed to be sure that any new approach would deliver benefits and not just more cuts to research and closure of valuable ag research facilities.

"I am concerned that assets will be sold off to prop up Labor's massive $65 billion bubble of debt ... we must ensure that out of all this comes better training and courses to provide workers for our primary industries," Mr Horan said.

This claim prompted an angry response from Mr Mulherin, who said he had "made it absolutely clear" that "funds raised from selling some old and outdated facilities would be re-invested in new state-of-the art facilities".

"Any astute businessman, or in this case a Smart State Government conscious of how it spends rate-payers money, knows that you must divest to re-invest," Mr Mulherin said.

"To claim that we are looking to do otherwise is just mischievous and to drag out the same old, discredited lines about the budget and staff numbers shows how far removed the Opposition is from reality."
