The National Farmers Federation has again called for quadbike safety regulations.

National Farmers' Federation president Fiona Simson says the government must stand up to manufacturers and force them to include protective devices.

“What will it take to enact change? How many lives need to be lost? How many people need to suffer life-altering injuries before the government will act to make quad bikes safer,” she said.

The call was sparked by the death of a cattle farmer in central west NSW, who was found crushed to death under the four-wheeler, making him the eighth person to lose their life in a quad bike-related accident this year.

That incident occurred just one day after four people were admitted to hospital after a quad bike accident near Mackay, and two days after a teenage girl suffered serious chest and spinal injuries in north Queensland.

The consumer watchdog has also recommended making operator protection devices on all new quad bikes mandatory within two years.

The government says it will make a decision after a third round of consultation in June.

The companies that produce quad bikes have been lobbying ministers against having to make their products safer.

Bike manufacturers claim that research on devices is inconclusive, and has raised fears they could cause more injuries.

The Royal Australasian College of Surgeons, Country Women's Association, Royal Flying Doctors Service and Australian Workers' Union are all in agreement with the NFF's stance.

But former agriculture minister David Littleproud has also questioned the research into roll devices for quad bikes.

The final decision rests with Assistant Treasurer Michael Sukkar.
