Katrina Gorry has never seen such a buzz around the Matildas, but says their performances against the world's best make it justified.
Australia came through the group of death at the Women's World Cup before beating Brazil 1-0 in the last 16.
With that victory, they become the first Australian team – male or female – to win a match in the knockout stages of a World Cup.
Gorry said testing, and beating, some of the world's best had led to confidence.
"Definitely [the most buzz]," the star Brisbane Roar midfielder said.
"A lot of people have always known what we are capable of, but to see it against such great teams such as Sweden, USA, Nigeria and then against Brazil, I think it really boosts the confidence people have in us.
"It'll be exciting to hit the quarter-final."
It was Gorry's wonderful through ball that led to the winning goal against Brazil as she played Lisa De Vanna through.
De Vanna's shot was saved, but Kyah Simon was on hand to put away the rebound in the 80th minute.
The 22-year-old 2014 AFC Women's Player of the Year said the Matildas had to improve on that display.
"We've still got to build on that performance," Gorry said.
"There's a few things that we need to work on and we'll try and bring that into the next game, but we have a few days to recover and prepare so we'll be coming out firing in the quarter-final and be ready."
