Terms of reference for the probe were released on Wednesday by the Community Development and Justice standing committee.

It will examine whether current laws, regulations, policies and practices are adequate to protect workers at fly-in, fly-out sites.

The committee, chaired by deputy Liberal leader Libby Mettam, will also scrutinise workplace culture, rosters, drug and alcohol policies and recruitment practices.

Written submissions will be accepted from members of the public until August 6.

Several women have come forward to police in recent weeks detailing claims of sexual assaults at major WA mines.

Australia's mining industry has promised it will take action to protect workers.

Senior executives from BHP, Rio Tinto, Fortescue Metals Group, Woodside and Newmont last month held a joint press conference to apologise to victims of harassment and back calls for a parliamentary inquiry into the issue.

BHP earlier this year introduced alcohol limits for workers at its camps amid concerns about a culture of heavy drinking.

The Minerals Council of Australia on Wednesday released a national industry code on eliminating sexual harassment, emphasising that all employee allegations must be treated seriously, confidentially and sensitively.

Member companies are required under the code to provide alternative working arrangements to assist victims, facilitate access to support services and take reasonable steps to protect individuals from "victimisation or reprisals".

Criminal conduct must be referred to authorities and outcomes of completed investigations communicated in a timely manner.

The code also encourages companies to "avoid the use of non-disclosure clauses in any agreements with persons impacted by sexual harassment."

"Sexual harassment causes profound physical, emotional and psychological impacts on those affected. It is unacceptable, against the law and must be eliminated from our industry's culture and workplaces," the council said.

"A uniform national approach enables all employers and workers to have the same expectations for respectful workplaces regardless of their location, job, gender or seniority."

A "safe and respectful behaviours" working group has meanwhile been established by the Chamber of Minerals and Energy.

The group plans to develop a code of conduct which will focus on employee behaviour after hours on site, at external events and on social media.

A report by the Human Rights Commission last year found 74 per cent of women in mining had experienced harassment in the past five years.
