The two-time A-League winning championship coach is free to return home with the Victory, having resigned from his post at the Roar on Tuesday
Postecoglou, 46, has been heavily linked with a move back to his home-town to coach Victory in the last few months. His resignation ended speculation over his future on the Roar, just two days after leading the club to back-to-back A-League titles.
Speaking on Fox Sports FC on Tuesday night, Postecoglou said he was hopeful of completing the move in the coming days.
"There's no secret about where I'm likely to end up. There are some things that still need to be finalised and hopefully they will over the next couple of days," Postecoglou said.
"I didn't want to talk about the future today, even in Brisbane, because I want to be respectful to the club that I have coached.
"It's important I close that chapter in the right way because the club deserves that, the supporters deserve that, and then I can talk about my future when and if it's decided."
Roar assistant Rado Vidosic appears destined to fill the now-vacant position at the Roar, and Postecolgou indicated he would not be returning to his former club for players if he was to move to the Victory.
The former South Melbourne and Young Socceroos coach said he was pleased to be leaving the Roar with a 'strong foundation', adding his decision to move on was difficult to explain.
"I'm constantly trying to see where I'm at as a coach, what I can do next and the players will tell you I'm always on about complacency and not getting comfortable," he said.
"There's many challenges at Brisbane Roar still to be had but there was something inside of me the last couple of months that got me a little bit restless and got me thinking about things.
"I probably made a decision about a month ago but I haven't been batting away the questions, I literally have been just focusing on the grand final and I've said to everybody - whether that was suitors or Brisbane Roar - that I didn't want to talk to anybody that I wasn't going to."
