Fresh from last month's Tournament of Nations triumph in the US, the Matildas captured the hearts and minds of their home public with Saturday's 2-1 win in Penrith and Tuesday night's 3-2 victory in Newcastle.
Not that the nation wasn't already on board with the game's biggest female stars - quarter-final runs at the 2015 World Cup and 2016 Rio Olympics made sure of that.
But for Stajcic, who's overseen his team's evolution from relative underdogs to world powerhouse, there's something different about this.
Some of it is easily measurable, such as the combined turnout of more than 31,000 and the fact Tuesday's crowd of 16,829 is a record for a stand alone Matildas home game.
Other factors are less explicit but almost as tangible, like the immense pulling power of Sam Kerr's awesome skill and celebratory acrobatics, Lisa De Vanna's penchant for a wonder-goal, and the squad's resilience to win emphatically despite conceding in the first minute.
"This week has been groundbreaking, a turning point for the game," Stajcic said.
"I think we'll be looking back in 10 years' time saying this was the week that football really turned in Australia.
"Like many people, I don't like to call it women's football - it's just football.
"To come out on a Tuesday night and have such a big crowd is a testament to how engaging the girls have been with all their media responsibilities, all the corporate engagements - the fan interactions have just been superb off the field.
"And when you play like that on the field the crowds are reward for all that hard work."
The world No.6 Matildas are set to re-enter the top five when the rankings are next updated - Tuesday's questionable late penalty call may have cost them a best-ever top-four spot.
Yet with an Asian Cup and all-important World Cup on the horizon, Stajcic remains far from content.
"If you talk to the players, I'm never happy," he said.
"There's always things to work on - there were periods where we lost control of the game and didn't get our rhythm the way we wanted to.
"To be a truly world-class team we need to be able to dominate for longer periods.
"We dominated for good periods and we're getting better at that, but we need to keep looking at the players finding the solutions on the field rather than coming into halftime."
