Stacey Waaka has scored nine tries at the World Cup, making the New Zealand centre a key concern for Australia in Sunday's final at Suncorp Stadium.
Jillaroos forward Sariah Paki expects captain Isabelle Kelly to handle the matchup, while drawing on her own experience facing Waaka in sevens.
"Stacey is an amazing player and I have versed her in many games over in sevens," Paki said.
"We know how we are going to play each other and I will definitely tip Izzy up about that. Those two will go well against each other and Izzy will definitely mark her up."
Paki will come off the bench in the final, seeking a third title this year after winning the rugby sevens World Series with Australia and the NRLW premiership with the undefeated Sydney Roosters.
The 25-year-old said the year recalled her 2022 sevens achievements, when Australia won the Commonwealth Games, World Series and World Cup.
"This feels pretty similar this time around. It has been a long journey, but I have loved every step of it. To win a World Cup would top my year."
After joining the Roosters to "try something new", Paki said she relished high-pressure matches but had to stay focused for 70 minutes, rather than sevens' 14.
She credited Kelly's guidance at the Roosters and in the Jillaroos; Kelly will play her 25th Test against New Zealand.
With Māori heritage, Paki said choosing Australia over New Zealand was difficult because of her family ties, but she wanted to play alongside Tamika Upton and Kelly.
"I feel like I made the right decision to come to the Jillaroos."
