The Wallaroos are champions of WXV 2 after taking out a 31-22 win over Scotland in Cape Town.
It was a dominant start for the Australians, who were forced to dig deep after a valiant fightback from the defending champions.
Even as the Scots went down to 13, they threw everything at Jo Yapp's side.
It set up a fairytale moment for Ash Marsters, celebrating breaking the record for most caps by an Australian with a last-minute try.
It also wraps up their qualification for next year's Rugby World Cup.
Here's what the players said after a monumental win at Athlone Stadium.
"We had a challenging start, had very little time together to prepare early on and that time is now starting to show what we can do on the field.
"Ultimately, the way they played and conducted themselves, they really are inspiring and for me, seeing them over the last couple of weeks in South Africa going into schools and engaging with young people, that's what it's all about and as people I'm really proud to coach them."
"The experience in Cape Town over the past few weeks has been amazing.
"I think for us having those two warm-up games prior to WXV was a real benefit. Although the results probably weren't what we would've liked to see, I think we learnt a lot from those both on and off the field.
"For the girls to group together, the coaching staff stay with us and stay consistent with their messaging and to come out with the results we have is pretty special.
"So good, it's unreal. This feeling is amazing, but I think we want to keep this up as a team.
"Next year, we're coming for you, everyone. Let's go!"
"It feels so good. We had a tough start to the year, but I think it's a credit to the girls, the coaching staff, the non-23, everyone in this environment, how well we stuck together.
"We knew the performances were going to come, so it's good to finally get that win.
"...I never had doubt that we'd get the (World Cup qualification. It took a longer process than what we planned, but I always had full faith that we'd get there. I think it'd be awesome being in England. They're really pioneering the women's game at the moment, so I think women's rugby's just growing and it's going to be an awesome crowd. I can't wait to work hard and get there."
"Woo! It's super special, a great building year.
"Obviously a rough start, but I'm so proud of the last few games and how hard we've worked together. It's really shown...We worked really hard all year and it's nice to finish off the year on a good note, on a win
"...It's so good to get the momentum from this and really fly into next year."
"It feels great, really proud of the girls.
"It's definitely a team effort and definitely wouldn't be here without the support of all of our families and friends so thank you Australia."
"It's pretty cool, pretty special.
"We've been on the road for a little while, so thank you to our families back home. Means a lot you stuck with us, so thank you."
