On day one of Australia's pre-tournament camp in Melbourne, the Socceroos coach was talking up his side's ability to make an impact both on and off the pitch.
It's hard to know what the bigger task might be: lifting the Cup or shining brightest in a busy Australian sporting summer.
The cricket Tests will give way to the World Cup in late January as the Asian Cup reaches a climax, with an Australia v India pool match due to coincide with a possible Socceroos semi-final.
The Asian Cup final also clashes with the women's final of the Australian Open.
But Postecoglou is not one to shy away from a fight and is embracing the twin challenges before his team and the sport.
"That's why I love Melbourne," he said of the sporting precinct and calendar.
"We'll be looking to make the Asian Cup the biggest tournament in the next month or so in this country.
"We've done a lot of build-up to it and it's great to see the players finally in."
Postecoglou was joined by veteran Mark Bresciano at AFL club Collingwood's training facilities on day one of the pre-cup camp.
Bresciano is one of 11 players from the 23-man squad to report for duty so far, with several players to finish their club playing commitments abroad by the end of the weekend.
Gathering the playing group together for the first time is a significant step for Postecoglou, who says he's more prepared for the continental competition than the FIFA World Cup in Brazil.
"It's been a pretty hectic 12 months but ... I'm pretty comfortable with where we sit," he said.
"The World Cup was all a bit rushed, we only had three games in the build-up, I was still getting to know the players and the players me.
"I'm a lot more comfortable now ... the whole feeling of the place (is) a bit more at ease with what we're trying to achieve."
