The White Ferns have acknowledged the enormity of the task ahead, as they begin preparations for next year's home World Cup.
Despite a difficult few months, the team are confident matches against the two top nations have given them the best possible preparation, as they set their eyes on World Cup glory.
The team's World Cup preparation is in full swing and some players are in for the biggest few months of their careers.
"For those that have been to World Cups, it is the pinnacle," all-rounder Suzie Bates tells Newshub.
The team's focus is now solely on the 50-over World Cup beginning in March in New Zealand, and after playing both Australia and defending champions England in the past 12 months, they know exactly what they've got to do.
"It's the most prep I've ever had leading into a World Cup," Bates adds. "In terms of games, in terms of camps together, we've left no stones unturned."
Although they lost more matches than they won across those series, their coach is confident it's not from lack of ability.
"We just didn't quite have enough self-belief," says coach Bob Carter. "A little bit of self-belief and a little bit of [a] change of mindset, and that's what we are working on.
"We are as good as anyone and we are improving."
The Ferns will have a chance for more game time, when they take on fourth-ranked India in February - just two weeks out from the start of the World Cup.
"I certainly want to win a series," adds Carter. "It would be a really good thing for us, if we can win a series, particularly leading into a World Cup."
"For me, playing against India in our home conditions... we want to be winning and we have the team to do that," says Bates.
Results are a must for this team.
"If we can get playing our best cricket by the World Cup, then I think we are in with a real shot," adds all-rounder Amelia Kerr.
Only time will tell if that's the case.
