The expiry of the previous deal - and the failure to strike a new agreement - meant A-League Men and A-League Women players had the option to exercise their right to industrial action, which was not permitted with an active CBA in place.
The APL has been locked in discussions for the better part of the year with Professional Footballers Australia (PFA), led by CEO Beau Busch, representing the players.
The APL said on Wednesday in a snap press conference that it was determined to resolve the A-Leagues pay dispute, offering to boost the ALW salary cap from $640,000 per club to $900,000 and offer a roadmap towards full-time professionalism.
"I'm confident we've put forward a compelling proposal, given where we got to in early July," said APL chief executive Steve Rosich.
"The passage of time and the consultation process with our stakeholders allows you to consider to add to this proposition.
"We think it is (a proposal) that's reflective of now, and that sets us up on a platform of growth going forward to share with the players."
But the PFA, responding to Rosich's comments, claimed the first they heard of this fresh proposal was a few hours before the APL boss hosted his hastily-arranged media call on Wednesday afternoon.
"The players overwhelmingly rejected the APL's previous final offer due to a fundamental lack of trust that it would have secured the leagues' futures after years of mismanagement," Busch said in a statement.
"The APL's conduct continues to erode that trust.
"It is disappointing that the APL has attempted to wedge the players with media tactics instead of engaging appropriately.
"We will now carefully review the APL's letter and will consider its contents with our members in the coming days.
"Five years of underperformance by the APL has left the game in an incredibly precarious position."
The APL said prior to Wednesday that it had previously agreed to 52 of 53 items with the PFA, but the ALW salary cap was the sole sticking point.
Rosich said the APL would define its blueprint for a move to full-time professionalism in the women's game over the coming year.
The APL boss appears confident that should both parties move closer to ironing out an agreement, the A-Leagues would stave off the threat of players taking industrial action.
"It (industrial action) hasn't been discussed and it doesn't make sense to be discussed (because) the majority of players are contracted," Rosich said.
"We've got a framework to take us forward, which is reflective of the now and includes some important increases in the women's (cap)."
The APL has offered players the chance to have a seat at the table and influence the decision making process in the leagues' direction, with many players dissatisfied with the competition's lack of profile.
The fresh attempt to strike a deal contained no suggestion of alterations to the ALM salary cap or the number of allocations for marquee player contracts.
Marquee deals sit outside the salary cap of $2.6m.
