Alen Stajcic's side, nicknamed the Matildas, were due to fly to the US on Friday (September 11) to play two matches on September 17 and 20.

The Professional Footballers Australia (PFA), however, have stated that the FFA has not addressed concerns raised by players and the trip has now been called off.

PFA, who have been negotiating a pay deal as part of a collective bargaining agreement, had already instructed players to miss the final training camp in Sydney ahead of the tour and a session yesterday was cancelled.

There was also a boycott of commercial and school events players were due to attend in Perth last week, and the Matildas players have reportedly not been paid for two months.

“The players are currently uncontracted and are under no obligation to participate in any Matildas related activities,” said PFA chief executive Adam Vivian, who informed FFA of the decision following a meeting involving players today.

“The players feel they have been left with no option other than to take this course of action.

"They were hopeful that FFA’s position would alter following yesterday’s breakdown in negotiations.

"However, the interim letter agreement offered to the players this afternoon, with a 6pm deadline, proved this had not been the case.

“As a result, the players rejected FFA’s proposal for the tour, which would have not provided the requisite a high performance environment, failed to fairly remunerate them for the work they were being asked to undertake and provided them with no contractual certainty following the conclusion of the tour.

“The offer from FFA was simply unacceptable.

"The players' stance will not change until a new agreement is reached.

“The A-League and Socceroos players have also expressed their full support for the Matildas in their pursuit of a deal that respects their contribution to the game.”

Earlier, FFA had slammed the PFA for "taking action without notice" to disrupt the team's tour preparations.

They claim that PFA withdrew from previously agreed positions and tabled a fresh set of demands, including significant increases in spending on air travel, accommodation and benefits for Matildas players,

FFA say it was previously agreed that funding for the women's team would be initially devoted to a 10 per cent pay increase, with annual increases rising to 15 per cent.

Meanwhile, further PFA demands are said to include an immediate AUD$1million (£458,000/$703,000/€631,000) increase across ten clubs in the salary cap of the A-League – Australia's top men's club competition – and a pay rise of AUD$1,000 (£458/$703/€631) per match for men's team players, the Socceroos.

“It’s sad that the Matildas have been dragged into a dispute that’s primarily about the A-League," said FFA chief executive David Gallop.

"The offer to the Matildas would basically double their pay over the next four years.

“Since talks began seven months ago, FFA and A-League club representatives have opened the books to show the PFA exactly what the game can afford and what is possible with an improved TV deal in 2017.

“The new demands are simply not affordable and the PFA knows it.

"The deal put on the table by FFA represents the best pay and conditions ever presented to Australian footballers, with a guarantee of 30 per cent of uplift in new TV revenue going straight to the salary cap.

“FFA will continue to pursue an agreement that’s sensible and protects the interests of the game, it’s time to reach agreement and stop the game-playing.”

The Matildas reached the quarter finals of this year's Women's World Cup in Canada where they were beaten 1-0 by eventual runners-up Japan.

Meanwhile, A-League clubs have hit out at the AUD$1million salary cap increase, which would then be doubled in the 2016-2017 season.

The total payments would come directly from all ten clubs, with an equal split, but in a statement Adelaide United chairman Greg Griffin called this "economic vandalism".

"The PFA has shown its reckless regard for the clubs who collectively employ over 200 professional players,” Griffin said.

“The demand for another AUD$3million in payments is a dangerous folly, especially in such a young league.

"Do they want to send clubs broke before they comprehend the damage?"

Earlier this month, Australia's men's coach Ange Postecoglou said it was "not good enough" that the dispute had affected his side's preparations for World Cup qualifiers against Bangladesh and Tajikistan, but this did not sit well with his employers FFA and he has now retracted his comment.

"As a senior employee of Football Federation Australia (FFA) I understand that my comments were inappropriate,” said Postecoglou.

“I appreciate that I need to take sides on this issue.

"The commercial performance of the Socceroos brand directly affects the amount of investment in the match schedule, technical developments and sports science staff.

“In this case, the commercial boycotts imposed by Professional Footballers Australia (PFA) will directly affect commercial partners and will inevitably hurt the Socceroos program.

“I made comments out of frustration.

"I acknowledge that the PFA initiated the regrettable situation that has distracted us in Perth.

"I understand that FFA was compelled to respond in order to explain its position to the game's stakeholders.

“I call on the PFA to undertake that no future Socceroo camp will be targeted in this way.”
