Stajcic - who vies with Asian Cup-winning Tom Sermanni for the title of being the Matildas' most historically successful coach - was controversially sacked after an FFA board meeting amid allegations of a toxic culture among the playing group.

The sacking comes just months before the Matildas 2019 World Cup campaign, where the sixth-ranked side are one of the pre-tournament favourites. It also comes during Australia's bid to host the 2023 Women's World Cup.

"We believe there needs to be a proper independent investigation and an open report of findings of the relevant processes followed, including the roles of staff and board members in the lead up to and during this crisis," an FSA statement read.

"At risk is the credibility of the FFA Board, and critically the ongoing management and operations of the women’s game in Australia.

"The coaching situation is an unneeded distraction, and potentially undermines the campaign of the Matildas for the Women’s World Cup at France 2019 where the player’s focus is critical.

"The football community including tens of thousands of loyal fans of the Matildas deserve detailed answers and solutions to restore confidence across all relevant stakeholders."

FFA Chairman, Chris Nikou, recently broke his silence on Stajcic's sacking, justifying the board decision while maintaining that he was unable to provide exact reasons for the coach's departure.

"I think you'll appreciate that my hands are tied to a certain extent about what I can and can't say about what's occurred," Nikou said.

"This was not a decision taken lightly.

"It was after due consideration in consultation with the management team based in part on surveys but based in part on other information before the board."
