FFA, PFA long way from new CBA
Negotiations between the parties on Thursday broke down, with no further meetings set.
It means the current agreement, which expires on June 30, is almost certain to run out before another is agreed.
PFA chief executive Adam Vivian has written to FFA to schedule another meeting.
The major issue between the parties is FFA's desire to freeze the salary cap at $2.55m.
PFA president and Brisbane Roar captain Matt McKay said it was one of several issues.
“FFA’s insistence that the A-League salary cap be frozen for the next two seasons is a major sticking point in the negotiations, as is the need to solve the well documented concerns over the pay and conditions of Matildas players," he said in a statement.
"Furthermore, FFA has proposed substantial cuts to the pay of Socceroos.
“The players acknowledge that these are fundamental obstacles that have to be overcome if a new CBA is to be reached. Despite this, the players remain committed to continuing to pursue an agreement and at no stage have we abandoned the negotiations.
"At the heart of the negotiations is a simple requirement that the players receive a fair and equitable share of the revenue generated by the professional game, which must be contractually provided for in the new CBA."
McKay said the cap freeze and Socceroos cuts came at a time the game was "generating record revenue and follows four years of wage restraint".
He said FFA's proposal had been delivered as an "ultimatum".
FFA hit back in a statement of its own, with Greg Griffin – who represents club owners on the joint FFA-clubs negotiating team – saying the PFA had turned down "the best package" ever offered to Australian players.
“The offer put jointly by Football Federation Australia (FFA) and the Hyundai A-League Clubs represents an immediate increase of up to 12% in payments to A-League players, coupled with increased investment in the PFA Player Development Program," he said.
"Further, the offer included the introduction of a player registration embargo on Clubs who default on the payment of remuneration and entitlements to players as well as increases to the Salary Cap Floor and Minimum Salary.
"In taking this step, the PFA appear to be showing a lack of regard and appreciation of the efforts of the many people who work in the Clubs both on a paid and volunteer basis to put the best teams possible on the park in challenging times.
“The current economic circumstances surrounding the A-League are not conducive to securing a return on all of our substantial capital investments, but we continue to make investments in the competition to underwrite the employment of 230 professional players and to operate clubs that our members and fans can be proud of."
While McKay said the PFA never abandoned negotiations, Griffin claimed the body had decided to "walk away from the CBA negotiations".
