It's hardly been a case of baby steps for Angeball.
In just one season Celtic have used it to sweep all before them on the domestic stage and the proof should come at Tannadice tonight when manager Postecoglou and his players hope to wrap up a top flight title to go with the League Cup which is already on display in the cabinet.
But now Carl Starfelt believes the next stage of this Aussie revolution will be rolling it out across the continent in next season’s Champions League.
If there has been one source of regret from an otherwise spectacular first season in Scottish football, it will go down as a recurring nightmare which saw Postecoglou’s rebuilt side knocked out of three European competitions in one campaign - as rivals Rangers have stormed to Seville
But Starfelt believes the lessons learned along the way will stand Celtic in good stead to make a proper entrance to the biggest stage of the lot next time out.
The Swede said: “The Champions League is huge, obviously. In club football it’s one of the biggest things you can do so it would be massive for all the players and massive for the fans and the club. Everyone would look forward to it.
“We’re not thinking too much now about what could have been in Europe this year. We learned a lot from playing in these games and although not everything was perfect we went out there to play our football 100 per cent.
“What we know is that it requires a little bit more in Europe. But if we do that then we can also see that it works.
“So the team learned a lot from being in Europe this year and hopefully we can take that into the Champions League next year.”
For Starfelt, it will also present an opportunity to follow in the footsteps of countrymen Henrik Larsson, Johan Mjallby and Mikael Lustig and he nodded: “Of course, when you come to a club like Celtic you want to win titles, you want to play in Europe and perform well there. That’s one of the reasons I chose Celtic in the first place because it’s a great club for doing that.
“The Swedish guys are obviously an inspiration. It would be good to do these things regardless but Celtic has great reputation in Sweden and it makes it a little bit more fun maybe.”
But first Celtic must seal the deal by taking at least a point away from Tannadice tonight - before the celebrations can really begin.
Starfelt said: “Of course. It’s going to be a very big game for many of our players, including myself. It’s the chance for me to win my very first league title so that makes it a huge day for me. Hopefully, we can secure it tomorrow.
“I know we’ll have a lot of Celtic fans there so it would be great for them, the players and the staff if we can get this done.”
And Starfelt will be hoping for more good news this summer as Celtic look to tie up a permanent contract for his friend and central defensive partner Cameron Carter-Vickers.
He said: “Cameron is a very good player and easy to play with. But also, our relationship is very good, the chemistry is very good.
“We have become friends outside the pitch as well and we can speak freely about situations.
“So that helps and, yeah, we have an understanding about each other and each other’s games and what we want and what we need from each other.
“Of course I would like to play with him next season because he is a very good player. But we will wait and see.
“I know nothing more than you guys. I don’t think it’s up to me to persuade him. We will wait and see, it’s not up to me whether he stays or not.”
