FFA issued a media release this morning in which it said changes had been implemented in several key areas, including loyalty player and home grown player allowances, mature age rookie payments, marquee player payments and the minimum annual salary for players over 21.
The head of the A-League, Damien de Bohun, was quoted in the release talking about the changes.
He finished by saying: "On top of these changes, FFA continues to work with the PFA to finalise a Collective Bargaining Agreement that will ensure player salary growth increases in line with the growth of the sport."
PFA has responded by questioning how FFA can introduce contract regulations while the CBA negotiations are ongoing, and how genuine those CBA negotiations are as a result.
Adam Vivian, the PFA CEO, said in a media release: "The decision of FFA to unilaterally impose their own player contract regulations whilst CBA negotiations are ongoing is of significant concern.
"Many of the regulations imposed are still being negotiated and agreement is yet to be reached. This raises questions as to whether negotiations are being conducted in good faith by the federation."
PFA had hoped to put a recommendation on a new CBA to a vote of its members at a mass meeting of players in Melbourne last Sunday, but it was unable to because further negotiations with FFA last week had not resulted in a final agreement.
It remains to be seen whether the CBA negotiations resume or whether this latest development results in PFA considering its legal and industrial options.
