Football Federation Australia has slammed Brisbane Roar's failure to pay players and staff for the month of June as the embattled A-League club's financial issues continue to fester.
As the pressure mounts on Indonesia-based owners The Bakrie Group, an internal e-mail addressed to Roar staff leaked on Tuesday, detailing the club's "very serious financial liabilities" and flagging possible legal action against former managing director Sean Dobson.
The letter said the Bakries have promised to inject a further $3.5 million into the club's coffers but it has not yet been received, leading to the non-payment of wages which were due on June 15.
An FFA spokesman said it was "unacceptable" for an A-League club not to meet its obligations to players and staff.
"Football Federation Australia (FFA) is aware that Brisbane Roar has some financial issues," said the spokesperson.
"FFA stresses that the non-payment of players and staff is unacceptable and needs to be resolved urgently by Brisbane Roar."
Professional Footballers Australia, the A-League players union, said it had been seeking an immediate resolution to Brisbane's cashflow crisis.
"The non-payment of players is completely unacceptable, with the situation at the Roar further highlighting the players' concerns regarding the good governance of the A-League," a PFA statement said.
"Over the history of the A-League players have consistently been the victims of poor governance and the PFA will continue to seek reforms to ensure the reputation of Australian football is enhanced and that its governance is the world's best.
"The PFA will continue to support to the players during this difficult time and commends them on their professionalism in the face of adversity."
It's understood the letter sent to Roar staff was edited before it was made public due to potential legal issues.
One part read: "To be completely transparent, since the sudden departure of the Managing Director last month we have uncovered very serious financial liabilities."
"(Interim chief executive) David Pourre and myself have been working tirelessly over the past 5-6 weeks uncovering more damage and we have a worked on a re-structure plan that will return the club to a healthy position."
More financial problems could be on the horizon.
Major backer The Coffee Club's sponsorship deal with the club expires on June 30 and it's believed the company will not renew.
The Coffee Club is part-owned by Emmanuel Drivas and Emmanuel Kokoris, who are both former Roar shareholders.
Meanwhile, hours after the letter emerged, the Roar appointed former skipper Craig Moore as football operations manager.
Moore will work as the right-hand man of newly-installed coach John Aloisi, having recently served as an elite player mentor for FFA.
"It's great to be back at the club at such an exciting time," Moore said.
