WAFarmers policy director Alan Hill said the rural lobby group acknowledged growing concerns surrounding plant breeding companies like Monsanto, their patents and paperwork but the reality was growers would continue to base GM choices on their farm's bottom line.

Mr Hill said the move towards plant breeding privatisation was at the forefront of farmers' minds but the level of support for the use of and research into GM technology in WA hadn't changed.

"In the last five or six years of our GM policy review grower feedback has been remarkably consistent," Mr Hill said.

"The only real exception to that was when the State Government introduced significant changes in 2010/11 and the industry moved GM trials and commercial evaluation into GM crop use."

But despite the fact WAFarmers' GM policy remained almost unchanged in 10 years, Mr Hill brushed off suggestions of policy irrelevance and said WAFarmers members wanted to continue with the GM policy forum on a yearly basis.

"In the early years before the State Government allowed the commercial use of GM crops our focus was on access to the technology," Mr Hill said.

"These days we don't review it in response to a specific issue or event but rather as a matter of course."

Mr Hill said it was difficult to second guess the WAFarmers membership and in previous years the policy had been reviewed in response to particular activities, though he wouldn't disclose which ones.

"The annual review is about our position on the support of the technology as opposed to specific incidents," he said.

"We haven't had any specifics to look at to date but having said that we haven't finished all our zone meetings throughout that State at this point in time."

As a result of the commercial uptake of GM canola in WA in 2010, last year WAFarmers made a minor change to its policy wording which reflected the group's ongoing role in supporting the development of GM protocols.
