The Roar atoned for a lacklustre performance last week in front of a dismal crowd when they went down to bottom of the table Adelaide United by dominating the Fury and giving the 11,500 Suncorp Stadium fans an early Christmas present.
Postecoglou said the performance was of high quality and was proud of the way his charges bounced back and was hoping this result was a sign of things to come.
"We looked lively right from the start and we took the game to the opposition which is how you want to play at home," he said. "I thought we were always threatening and pretty solid in the back.
"It was a good night by the boys and did just about everything right.
"We are starting to get out the team I want to play and I think is the future of this club," he added.
"We know what we're doing and we've got an exciting group of young players who are all committed ... and that's who we are going to build this team around."
The Roar got the points thanks to a brace from striker Sergio van Dijk but the Dutchman preferred to thank his teammates for doing all the hard work rather than take the accolades himself.
"Scoring goals is always good for a striker but I have to give the credit to all the other guys who set the goals up," van Dijk said.
"We can't forget all the other guys did a good job and we played some good football to get the goals."
The win pushed the Roar up to 7th on the league table and now they will prepare to back up for Saturday's Round 20 clash with the Central Coast Mariners.
