The call from Brad Pettitt, Sophie McNeill, Jess Beckerling and Tim Clifford came on Friday night, after this masthead revealed that the Greens had created and maintained a secret dossier for 10 years cataloguing allegations against Steele-John and setting out ways to shut down media coverage and monitor members who raised concerns.
Steele-John took leave this week after seven Greens members wrote to federal leader David Shoebridge regarding "multiple allegations" about "his behaviour in the presence of women" between 2017 and 2025. The senator strongly denies the claims, describing them as non-specific.
Shoebridge has ordered an independent investigation into allegations that Steele-John made multiple inappropriate comments to women, but has refused to say whether the results should be made public.
In a statement, the four WA state MPs said they considered "any allegations of this nature to be serious and concerning, especially when they involve elected representatives".
"Women deserve to feel safe always, and must be able to bring forward complaints safely, and be heard and taken seriously when they do," the statement said.
"We agree that this matter needs to be resolved via a fair, timely and independent investigation and that all parties are entitled to natural justice and procedural fairness."
