Western Australia have joined the country's bid to host the FIFA Women's World Cup in 2023, while the Socceroos have been locked in to return to Perth next year.
NSW, Victoria, Queensland and South Australia had already agreed to be part of the FFA's Women's World Cup bid and WA confirmed their participation on Saturday.
Should Australia's bid be successful, Perth will host World Cup games at HBF Park, where Perth Glory play.
Perth fans will also get the chance to see two Socceroos matches over the next two years.
The Socceroos will host Kuwait in a World Cup qualifier at HBF Park on March 26 next year and should the Socceroos reach the third round of qualifying as expected, Australia will play in Perth again in 2021.
