Buoyed by signs of life from the stricken Jets in the dying embers of this campaign - culminating in Friday's stunning 1-0 upset win over ladder leader Melbourne Victory at AAMI Park - Tinkler said it's time for Stubbins' army of detractors to cut him some slack.
Vilified for presiding over just three wins in 25 games in a season which has seen mass sackings of players and the exits of coaching staff, Stubbins, according to Tinkler, will prove the doubters wrong.
"I have no reservations in supporting him. He has done everything he said he would do in the face of some fierce criticism," he declared.
"I think there are 25 million soccer coaches in Australia at the moment, everybody has an opinion and many would do things differently while there are some there that would support him.
"I beleive he can do a job for us … he has made some brave decisions to try and take us forward.
"We had an established losing culture at the club and it didn't matter who we were going to bring to it, it wasn't going to change.
"He needed to take action and I understood the reasons for that.
"I am sure it will pay dividends in time. Unfortunately, it's too late this season but we have plenty to look forward to next year."
Fed up fans vented their anger during the Jets' 2-0 loss to Perth at Hunter Stadium in Round 24, unveiling a giant banner which read: 'Enough failure, lies and arrogance. 10,000 fans demand the Muppet gone'.
Tinkler was unimpressed by the caustic reference to his coach, adding: "He's a real man, a good guy and a good character.
"I'm looking forward to coming to our final home game of season against Syney FC on Friday night, having a beer with Phil and laughing about some of these banners.
"Anybody content to keep getting beat I wouldn't call a supporter. The people who are whingeing and blogging their hearts out, carrying on and holding up banners and stuff, I wouldn't say they were true supporters.
"You don’t change culture at a club without some major decisions and it takes a bit of real commitment to do that. Phil's put himself on the line, made those calls and it may just pay off for him.
"The previous two weeks we were unlucky to get beat (against Adelaide and Glory) … and I was very happy for the win against Victory.
"But I can't say it was a shock given how we have been playing. We have turned around season a bit and that's a credit to coaching staff and the players too ... a lot of those guys have been unfairly portrayed.
Tinkler contends that Stubbins has found the right template for the future.
"Next year the enthusiasm and will to win won't be going away," he said.
"Phil wants to play an entertaining game. We had to stop conceding so many goals and become hard to beat first and foremost and now you seeing another feather to his bow in an attacking sense.
"Bloggers can complain all they want but a team doesn't change overnight … it takes time and we are building now to be a real threat for the start of next year.
"In Newcastle he has been treated pretty harshly by the media … outside of Newcastle people seem to be picking up on some of the positive changes that have been made at the club."
With his own position as club owner being closely monitored by FFA over the scheduling of payments to club creditors, Tinkler said: "With the FFA we have taken care of some big issues and now we are taking care of some of the smaller ones. This is not the EPL, we don't have those types of finances but we are working through our issues.
"I am hoping to be in a position to look at marquees and really shake up the squad for next year."
Tinkler would like to attract an Emile Heskey-type figure up front, fondling recalling the veteran Englishman's spell on the Hunter.
"We'd love to have some body of Emile's stature again. He was great for us … he didn't just do well on the paddock but he improved those around him and it was a pleasure to have around the club. Someone like that would be ideal for us."
