Sharni Williams wants the Wallaroos to brandish some trademark Aussie mongrel, ahead of their final pool match against Japan.
Williams will captain the Wallaroos for the first time on Friday, with regular skipper Shannon Parry out through injury.
That pair co-captain the Aussie Sevens side so Williams has plenty of experience with the armband on.
Despite that, Williams feels she has big shoes to fill in Parry's absence.
"It's big shoes to fill but I'm absolutely honoured to captain the 15s for the first time," she said.
"Just adding a few more girls that I have to look after and guide on that field.
"At the end of the day when it comes down to the game, we are out there, the coaches aren't out there.
"We're out there together and we have to have that trust and belief in each other."
Williams expects Japan to shoot out of the gates firing, just as France did on Monday.
To ensure her side doesn't go into their shell, as they did against France, Williams hopes to reinvigorate the side with some trademark Australian mongrel.
"We were probably a little bit surprised from that kick off, France came out firing and that is exactly what Japan are going to do," she said.
"Going into this we have said that Japan were going to knock off a team and let's hope it's not us.
"We are going to go out there, fight for each other and bring that Aussie mongrel."
The loss to France puts semi finals football out of the equation but a fifth placed finish would improve on the 2014 result, in which the side finished seventh.
That's now the team's top priority and Williams certainly didn't mince her words when asked what the Australians have to play for.
"It's devastating that we can't make semis, we have put our heart and soul into this, but we've got to set goals each time something doesn't go our way," she said.
"We have to look at what can we do now, how we can go forward from here.
"The next best option is fifth and we have a group together here that believe each other and that's what we are going for, that fifth position.
"We're playing for pride, playing for our country, playing for each other, playing for the girls back home that didn't get to make it on the team, playing for the young girls at home that are looking to play 15s or Sevens, keeping the dream alive of rugby in Australia."
