And the peak body representing players says the low pay could be discouraging up-and-coming female talent.

The issue dampened celebrations after the Matildas became Australia's first senior team to win a World Cup knockout game with a 1-0 win over Brazil on Monday (AEST).

Each Matilda was paid $500 in match fees for the games leading up to their historic round-of-16 effort.

Their male counterparts receive $7,500 for doing the same thing.

Match fees increase as a team progresses through a tournament and are paid on top of other income.

If the Matildas make it to the final in Canada, they will earn a total $5,600 in match fees while the Socceroos, under match fees higher than they are now, had the chance to earn $69,000 during last year's World Cup.

A Professional Footballers Australia (PFA) spokesman said the representative body was in negotiations with Football Federation Australia (FFA) over the Matildas' collective bargaining agreement.

He said the PFA considered the Socceroos' remuneration to be deserved but the Matildas' low pay was a hindrance to development.

Investment must increase for sake of women's game: PFA

According to the spokesman, the game has to try to increase its investment in the women's game to make sure the Matildas reach "fair, equitable and attractive" levels.

"The attractiveness of the career path for the nation's top female players must be enhanced," he said.

"Remuneration is an important element in this and one the PFA and the players are looking to address."

On top of match fees, most of the Matildas earn $21,000 a year on FFA contracts.

The Socceroos do not have a guaranteed income but receive shares in a number of commercial agreements and sponsor bonuses instead.

Even without income from commercial arrangements, a Socceroo could make more than a Matilda's annual contract from the match fees of three tournament group-stage games.

The FFA did not comment specifically on the difference in match fees, but a spokesman said securing commercial contracts would be crucial to increasing pay.

He also said growing the women's game was strategically important for football in Australia and that the Matildas' World Cup success would open overseas career pathways to players.

"The results in Canada and the way the players have conducted themselves can only help in securing the commercial support that can drive significant growth in expenditure," he said.
