Australia’s squad have criticised the gender disparity in World Cup prize money and the fact some nations do not have collective bargaining rights.
All 23 Matildas players featured in a video posted by the Australian professional players union (PFA) three days before the tournament begins.
The squad also called for all of the players in Australia’s A-League Women to be fully professional.
Australia are co-hosting the Women’s World Cup with New Zealand.
“736 footballers have the honour of representing their countries on the biggest stage this tournament,” said Australia and Everton midfielder Clare Wheeler in the video.
