This week the National Farmers Federation, Farm Safe, Country Women's Association of NSW, Royal College of Surgeons and the University of Sydney met with politicians in parliament to ask why they haven't implemented the changes.

Central west farmer, NFF Workforce Committee Chair and Farm Safe chair Charles Armstrong said it was frustrating that nothing has been done despite earlier this year the ACCC made a recommendation to the Assistant Treasurer to make a mandatory safety standard.

"But it's also frustrating to sit across the table from various politicians who are inclined to believe the manufacturers and not listen to us in terms of carrying this out," he said.

Honda and Yamaha dispute the safety benefits of roll-over protection and threatened to withdraw their products from the Australian market if government mandates it is fitted to all new vehicles.

During the discussion at Canberra, Mr Armstrong said they were able to speak with the politicians about some of the misinformation and the horrible quad bike death statistics.

"We made some progress and I think we will get there in the end," he said.

"Apparently there is a final report to be received from ACCC even though they delivered their final report in February, but there is another to come and then it's expected the Minister will make a decision soon after.

"We should get some definitive position within the next three or four weeks."

Assistant Minister for Trade and Parkes MP Mark Coulton said he doesn't think roll bars will save all quad bike deaths, but it's not the inconvenience some have made out either.

"I know that you can't legislate for poor behaviour but I think this is far too important an issue to put in the too hard basket," he said.

The hold up poses issues for farmer safety, but also for quad bike dealers in Australia, Mr Coulton said.

"The roll bars could be retrofitted in Australia so it shouldn't be an impediment on bringing machines into the country," he said.
