Football Federation Australia chief executive David Gallop will address the shellshocked Matildas squad in Sydney on Monday as fallout from Alen Stajcic's sacking sends the national women's football team into crisis.
The Matildas are without a coach less than six months out from the World Cup in France, a tournament they were expected to challenge at.
Superstar striker Kerr encapsulated the mood of a number of players on Sunday when she said she was "shocked and upset" by the coach's dismissal.
It will be the fourth straight World Cup - two for men (Holger Osieck and Ange Postecoglou) and two for women (Hesterine de Reus and Stajcic) - where Australia's head coach has been replaced within months of the tournament.
Stajcic was sacked after two confidential culture reviews - the first conducted by FFA and the player union and the second by Our Watch, an organisation that tackles abuse and violence against women.
Precisely what prompted that second review is a tightly-guarded secret.
It's understood neither Stajcic himself or Matildas coaches or players have been made aware of the precise allegations.
Gallop will address the players on Monday morning at a pre-planned leadership summit in an attempt to give clarity on the decision and provide support to the rattled group.
Matildas have been told by FFA not to speak about Stajcic's removal.
One player told AAP, "we're all very confused and can't believe it. We're heading into camp tomorrow and want answers. But I can't talk to you about it."
Others took to social media to express their support for the coach who lifted Australia to their current world No.6 ranking.
Australian captain Clare Polkinghorne tweeted "What's he done for the Matildas and football in Aus is incredible".
Kerr broke her silence late on Sunday.
"My trust was in Staj to lead us to the World Cup final & I believe he was the best coach for that. Thankful for everything his done for me and the team," she wrote.
Veteran striker Lisa De Vanna posted a cryptic animated message with a woman exclaiming "the lies, the lies".
Former Matildas, led by Heather Garriock, have also voiced their support for Stajcic.
It remains to be seen how the Matildas will react when they gather in camp, but the team have shown their willingness to take collective action in the past.
In 2015, the team went on strike over pay and conditions.
The year before, they demanded de Reus be removed from her position, with Stajcic placed in her role.
Like Stajcic, related groups are asking for more information over FFA's move.
Football Coaches Australia boss Glenn Warry said the organisation was "seeking due process" for Stajcic.
PFA chief John Didulica said he felt for players, urging Gallop to be as clear as he can be with the Matildas on Monday.
"A number of players had very close and longstanding relationships with Alen so this will be a difficult period for them and our focus is on providing them with the necessary professional support.," Didiluca said.
"The players will be meeting with David Gallop on Monday and we trust they will have an opportunity to get a deeper understanding of FFA's decision."
Matildas assistant Nahuel Arrarte has resigned from his role and defended Stajcic as a man of passion and principles.
The Matildas are next in action on February 28 when they kickoff a four-team series on home soil against New Zealand.
