"The spirit of this team is back, it's very positive," said Klimkova. "We are making steps every day, on the field, off the field to work as a team that creates a safe environment when everybody is courageous. If we have it in our team consistently, it will allow us to perform more consistently during the game."
Klimkova added that the underwhelming campaign was part of the journey towards the 2023 World Cup, as she builds combinations and assesses individuals.
"It's normal, the team development takes a while," said Klimkova. "We are making steps forward but we are prepared to make a couple of backward steps. That's what happened [there] and sometimes you need to make those steps to go forward again. And we are going forward again."
The Ferns haven't beaten Australia in 31 attempts since a 2-1 win in Port Moresby in 1994, though the rivalry has been closer over the last decade, with three draws and some narrow defeats.
The Matildas have accelerated away again in recent years, highlighted by their fourth-place finish at the Tokyo Olympics. The recent quarter-final Asian Cup exit at the hands of South Korea was a shock, but Australia will still be warm favourites.
"In football everything can happen," said Klimkova. "We know we are facing really tough opposition. And this was our plan. We know we can learn from those games the most and having three points or any point from these two games would be amazing."
Klimkova plans to rotate the squad across the two games – "we are still in exploring mode" while also being mindful of results. Improving the flank defence was a major priority of this tour, particularly around marking in the penalty area and accurate clearances. There will also be a focus on combinations in possession – to allow better attacking penetration – and decision-making in the final third.
Klimkova admitted there would be some tough selection decisions, with more competition for places that at any time during her tenure, thanks to the progress of younger players.
Australian-born defender Ally Green is training with the team, ahead of her expected switch of allegiance later this year, and has made good progress, learning about the environment and the style of play.
Forward Emma Rolston is the only player in doubt for Friday's match, after arriving in camp with an injury niggle.
