Australian boss Postecoglou is relishing a “special” trip, adding: “I know how big this club is back home. For me to go back home as the manager of it, it’ll be emotional.
“There are a lot of guys I grew up with and shared a dressing room with who are diehard Celtic supporters. They are going to see their mate bringing their team Down Under.
“The people who love this football club in Australia, they’re all in. They’re going to be there at every game, at the airport, at every training session.
“Everywhere the players go, they’ll realise why this football club is so special and the reach it does have.”
Sunday’s draw with Hibernian saw Celtic drop points in the league for the first time this calendar year.
The league leaders, who remain three points clear, lacked cutting edge at Easter Road without strikers Kyogo Furuhashi and Giorgos Giakoumakis, who was missing because of illness.
The Greek striker “probably won’t start but might be involved” against St Mirren, said Postecoglou, who will “wait and see how he’s feeling”.
With just 10 fixtures remaining, the Celtic boss has challenged his side to stick to their principles as they prepare to face sides with something on the line.
“Every game does have an edge,” Postecoglou said. “Every team is playing for something, whether it’s avoiding relegation, getting into the top half, Europe, championships. There’s a fight for everything out there.
“Irrespective of that, we know that the next 10 games, every one is going to be a real arm wrestle. I don’t think you will find that any team is not going to fight for something in these games.
“St Mirren’s form has been as good as anyone’s apart from ours in recent times and we know that’s a danger.”
