"I'm so proud of the girls, I knew we were in it at halftime," Kerr said after the final whistle.
"There were a lot of critics talking about us but we're back so suck on that one! It's just outside noise, we don't listen to the haters.
"The reaction from the girls, you can see what it means to us. We were so disappointed after the first game.
"We haven't been reading (the criticism) but at the end of the day you can feel it.
"Social media gives people a platform to say whatever they want, so it was good to kind of send a message back home and send a message to the rest of the world.
"We knew this would happen.
"We knew people would be quick to judge but that's football and look what we did today. We had three different goalscorers and outplayed them most of the time.
"Coming back from two goals down with the pressure we had on us, it's pretty special."
Her comments have been both boldly celebrated and forcefully criticised by some football commentators.
Australia's most-capped Matildas great Cheryl Salisbury was among the first to question Kerr's colourful comments when speaking with Optus Sport after the dramatic finish.
"I probably would've chosen a few different words, but I was always a few years older when I took the captaincy," Salisbury said.
"But, it showed a bit of fire and a bit of passion, but also a bit of immaturity as well as a player and leader off the field as well.
"You've got to be able to do both, juggle both, be diplomatic occasionally when you feel something different and do what is best for the team sometimes and take away your personal opinion occasionally."
Matildas legend Heather Garriock also said Kerr's words have taken the focus away from the team's epic performance and shined the spotlight back on the pre-World Cup coaching dramas that have plagued the team in 2019.
"In terms of critics and outside noise, I think they need to focus on themselves," she said.
"If she is talking about the media, the Matildas shouldn't be listening to the media.
"When you're in camp, on the world stage, at a World Cup, you shouldn't be listening to anything other than the coach and your teammates."
Other football commentators have called for Kerr's post-game clapback to be immortalised.
Kerr says she hopes her team has also sent a message to the rest of the world that the Matildas are a legitimate contender to lift the trophy.
"Hell yeah," Kerr said.
"Well we've got to focus on Jamaica first, we're not gonna get too far ahead of ourselves.
"Brazil's one of the best teams in the world, they've got the best player probably ever in the history of the game (in Marta).
"So if people don't keep watching the Aussies, we'll come get ya like we did then.
"People don't understand the belief we have in this team, they don't understand the confidence we have in each other, the confidence we have in Ante (coach Ante Milicic).
"One game was not gonna derail our World Cup hopes — and that's why it was so frustrating for us because instead of the media being 'we can turn this around', it turned negative on us and it only fuelled us, so thank you."
Kerr was kept quiet for much of the first half but she saved her best work for off the ball. In injury time she moved away from the drop zone when a cross came in from the left, taking defenders with her. It gave Chloe Logarzo more room to move and her header found Caitlin Foord, who scored Australia's first goal.
Kerr also dragged defenders to the ball and they were so distracted by her they missed the most important thing on the pitch as Logarzo found an equaliser in the second stanza. The skipper played her part again when the Brazilian marking her scored an own goal to provide the Matildas' winner.
Australia coach Ante Milicic would have been a worried man sitting on the sideline watching his troops concede two goals in the first half but they dragged themselves back into the contest through sheer willpower more than anything else.
"It's a big result and we needed it today," Milicic said. "It was a real Australian performance from these girls and I'm very proud of them.
"I think to come from 2-0 down, if anyone questioned the character of this team they answered in the best possible way.
"Delighted for the girls because they really deserved that."
