The move comes after a late bid by FFA executives on Friday afternoon to demand federations fall into line with their limited changes, dismiss the congress proposals and begin work on a new more limited model.

Now though that FFA plea to block the changes seems to have backfired and galvanised resistance.

Unless chairman Steven Lowy can strongarm smaller state federations back into line to block the vote on Tuesday, it seems inevitable now the changes will go through, and will likely lead to the exit of the Lowy family from Australian football.

It will also stop any moves by FIFA to suspend Australia from international football, and allow the Socceroos to defend their Asian Cup crown in January, and the Matildas to compete at the Women's World Cup in France.

The joint statement added: "[We] look forward to ongoing collaboration to unify football."

This afternoon the peace deal was hailed by fledgling fans group Football Supporters Australia.

They added: "This is a welcome development. FSA will continue to advocate for full representation of fans in new #governance structures via Congress - reforms must be ongoing that give fans (major stakeholder group, not just SIG) a place a the table."
