Tinkler's four year and  seven month tenure as Jets owner ended abruptly on Wednesday when FFA revoked his franchise licence, just hours after he placed the club into voluntary administration citing liabilities of $2.7 million.

Tinkler then accused FFA of being "morally bankrupt" by forcing him out and threatened to launch legal action. But in an interview with the Newcastle Herald on Thursday, Gallop produced a scathing response, saying the man they call the "Boganaire" had sealed his own fate.

"I have no doubt Nathan went into the ownership with all the right intentions, and even had outbreaks of wanting it to work in recent times," Gallop said. "But it hasn't."

"Not paying wages, stadiums, training grounds, numerous trade creditors, owing millions in tax, owing superannuation for months – if you do it for long enough, maybe you start to convince yourself that it's normal and even convince yourself that it's right as an owner. It's not normal or OK. The contributions he has made, however significant, will be forgotten quickly. The community expects better.

"In a community like Newcastle, everyone knows the butcher, the baker and the candlestick maker. If they don't get paid, it has a ripple effect across the town."

Gallop, then the NRL's chief executive, noted that he had been "sceptical" about Tinkler's 2011 takeover of the Newcastle Knights and had been criticised at that time by former Hunter Sports Group chairman Ken Edwards.

"For Newcastle and Nathan Tinkler, I always thought it was a bad move and bound to end in tears," Gallop said.

In response to Tinkler's "morally bankrupt" accusation, Gallop said: "We reject any suggestions along those lines. This has gone on for many months now, with a number of changes of direction. The level of debt continues to mount."

Gallop was unconcerned by Tinkler's threat to sue.

"Obviously we've had lawyers involved around the Jets situation for many months now," he said.

Gallop said he sympathised with Jets chief executive officer Mitchell Murphy and predecessor Robbie Middleby, who too often had been dealing with disgruntled creditors.

"We are supportive of Mitchell Murphy, but like Robbie Middleby, he can't spend every day explaining to people that the cheque is in the mail," he said.

Gallop declined to comment when asked whether the Jets' liabilities were larger than the $2.7 million figure Tinkler volunteered. The Herald understands the debt is more than $4million.

FFA will ensure that players and staff, who have been waiting for their monthly pay for seven days, are paid on Friday.

All 15 contracted players will be offered like-for-like contracts with the new Newcastle entity.

The positions of all administrative staff and coaches are under review.

Locked out of their training base at Newcastle University because of an unpaid $40,000 in hire fees, the Jets will now use the Northern NSW Football facility at Speers Point as their interim headquarters.

FFA will sift through the Jets' creditors to assess, on a case-by-case basis, who will be reimbursed.

"That's a big exercise that will take some time to get on top of," Gallop said.

Gallop said many clubs had changed ownership over the history of the A-League and "transition usually produces a stronger club".
