Donachie had previously signed a contract extension with the Roar to the end of 2017, but paperwork by the club’s previous administration was filled out incorrectly, allowing the 23-year-old to leave at the end of the season.

It comes with the Roar’s owners under pressure from Football Federation Australia (FFA) to keep their A-League licence, and a day after the resignation of the club’s medical staff due to unpaid bills.

“I would like to say thank you to everyone at the Brisbane Roar. It has been a pleasure to be part of this great club and it is hard for me to say goodbye,” Donachie said.

Donachie’s defensive partnership with veteran Jade North was a key part of Brisbane’s success last season, finishing third and one game short of a grand final in John Aloisi’s debut campaign as coach.

They did all that despite a pre-season financial crisis plaguing their owners, Indonesian conglomerate the Bakrie Group – one that is rearing its ugly head again.

Brisbane have no CEO and the Bakries have been given until next Monday to show FFA their plans for the future of the three-time champions.

Then they have to pay around $500,000 in wages by June 15, or else FFA could strip them of their licence and run the Roar themselves.

Meanwhile, chief medico Tony Ganter has told the Roar he will stop working with them when the team finish post-season training at the end of the week, having not been paid for the past 30 days.

That could put them in breach of the A-League’s new collective bargaining agreement and trigger a transfer embargo or points deduction for next season.

It will also leave the club’s youth team, which plays in NPL Queensland, without medical care.

The A-League players’ union, Professional Footballers’ Australia (PFA), is closely monitoring the situation.

“PFA staff have been in contact with our members at the club, who have once again displayed remarkable professionalism in the face of the recent uncertainty,” a PFA spokesman said.

“The PFA will continue to work with FFA in pursuit of a resolution and welcome their recent public comments, which highlight our shared commitment to resolve the matter swiftly.

“Whilst it is evident that the A-League collective bargaining agreement has had a positive impact on bringing all previous outstanding financial obligations up to date, it is clear additional action is required in order for the club to meet the standards the players and fans rightly demand.”
