"The isolation and loneliness that can be experienced by FIFO workers and partners alike, while separated from loved ones and family for weeks on end, can be a challenge," FIFO Families founder and director Nicole Ashby said.

"If you have a predisposition to mental health issues, it can be amplified by FIFO."

Supporting the WA Labor Party's advocacy for an inquiry into "FIFO suicides" Ashby echoed the need for improved support around mental health.

"Anything that can be done to raise the profile of mental health in the broader community is a positive step," she said.

"It is important for people to be able to recognise when their mental health is being compromised and to know where to seek effective assistance."

FIFO Families provides FIFO workers and their families with the support needed to negotiate the challenges of the lifestyle, while enabling community connectedness.

"We advocate FIFO workers and their partners having a real level of preparedness before they enter the lifestyle - knowing what to expect is very important," Ashby said.

Many large resources companies have signed up with FIFO Families to extend the social benefits of the program to their workers, with Ashby saying it is something that needs to be done.

"With a realistic understanding of FIFO, there is less stress experienced by the FIFO worker and as a result we have FIFO workers that are safer, more productive and feel better about working away," she said.

According to WA Today, state Opposition Leader Mark McGowan is expected to move a motion for an inquiry into FIFO suicides this week.
