The latest suicide of a fly-in, fly-out (FIFO) worker should act as a wake-up call for the Western Australian Government, the Greens have said.

The death on Barrow Island in the past week is understood to be the ninth suicide in 12 months in the Pilbara region.

The Greens Member for the Mining and Pastoral region, Robin Chapple, said the State Government and mining companies have a duty of care to do more.

"We really need to nurture and care for and look after people who are working to earn the state its incredible revenue," he said.

"I don't think we can just wash our hands and say it's the responsibility of the individuals."

Mr Chapple said soldiers were given much more support.

"If we go to the Australian Defence Force (ADF), the soldiers are in a very similar situation," he said.

"The ADF go to great lengths to ensure that the soldiers and their extended families are really nurtured and looked after in what is in many cases a difficult environment.

"We're saying that the Minister [for Mental Health] really needs to take a bit of a handle on this.

"We've had a number of suicides already in the last [year] associated with FIFO workers and in my view that is not acceptable."

FIFO suicides going under the radar

The founder of support group FIFO Families said FIFO suicides were going under the radar.

"I think anything that we can do as a community to support mental health is a great initiative," said Nicole Ashby.

"Often it's something that does go under the radar, particularly in mining as well.

"It is difficult, particularly on some of the longer rosters if you're away for four weeks and home for one.

"You might be doing nine weeks on, three weeks off, out of Africa.

"Those longer times away from family can be quite challenging.

"Acknowledging that, and providing support and resources only makes the industry a better place to work."

Mr Chapple has called on Mental Health Minister Helen Morton to take action.

"I want the Minister to get much more heavily involved in terms of making sure there are programs and facilities available to workers who might find themselves in a stressful environment," he said.

"That also requires the mining corporations to be very vigilant about the members of their workforce and those who may be in stress.

Mr Chapple said there should be a concerted effort to tackle the problem.

"We really need a combined effort between government and industry to ensure that those workers who do find themselves in a depressed state, for whatever reason, are identified by the corporation and then managed carefully by the relevant mental health services," he said.

Minister says suicide prevention strategy being developed

Ms Morton said Rio Tinto's iron ore chief executive, Andrew Harding, had recently been appointed to the Ministerial Council for Suicide Prevention.

She said it was recognised that fly-in, fly-out workers have greater exposure to the risk factors known to contribute to suicide.

"Risks due to social isolation, family and relationship stress are greater for FIFO workers than others," she said.

"The research we have commissioned has informed our development of support resources that are soon to be released.

"It will also feed into the implementation of tangible actions as part of the next suicide prevention strategy currently being developed."
