“There’s Aussie Rules, that’s the indigenous sport of Australia. It’s kind of unique to them and they take great pride in protecting as their code. The rugby codes dominate.
“It’s very hard for football to make an impact in that space and I guess then the flipside of that is just how global the sport of football is.
“If I can compare that to a country like Japan, who also have the tyranny of distance and baseball’s pretty strong, they plant a lot of resources into football and you can see that’s making an impact. I don’t see Australia down that road.”
Japan was Postecoglou’s next destination when he walked away from the Socceroos job after he helped his country qualify for the 2018 World Cup.
The ex-Yokohama boss had managed Australia at the 2014 edition, but his departure seven months out from the global showpiece was a surprise and at the time he described the job as “taking a toll” both personally and professionally.
Postecoglou has been involved in coaching since 1996 and while he has taken the Premier League by storm so far, he does not expect his time at Tottenham to change the landscape of football in Australia.
“I don’t. I don’t know and maybe that’s just me, not being cynical, but I gave up that fight,” he explained.
“It’s a much easier space for me to live in because I was so frustrated for so long. It was my biggest frustration. One of my major drivers for doing what I did was to do that – to change football in Australia and that’s the reason I left.
“I felt I hadn’t made an impact at all. That’s easier for me to deal with than to think maybe I still can now with what I’m doing. I just think I’d be disappointed, so I’d prefer to think it’s not going to happen.
“I walked away from a World Cup. We qualified and I walked away. The reason I walked away was I just didn’t enjoy what I was doing.
“It’s not just doing the job and winning games of football, it’s got to be a higher purpose. My higher purpose in Australia was to change the game. I just don’t think that will happen.
“It was the right decision for me (to leave), it was the right decision for where I saw the next stage of my career and if I didn’t make that decision at that time, if I had waited until after the World Cup, I’ve got no doubt I wouldn’t be sitting here now.”
Postecoglou replied no when asked if he would manage Australia again and laughed off talk of replacing England chief Gareth Southgate.
He added: “England? Oh, come on mate. They’ve got a fantastic manager and I’m eight games into a Tottenham career. That’s how I think.”
