Kezie Apps has extended her Wests Tigers contract through 2029, when she will be 38, but the 35-year-old is not planning her retirement.
After Australia's 30-14 semi-final victory over Fiji secured a World Cup final against the Kiwi Ferns, Apps said she was focused on the present.
"I don't want to use that word just yet. I'm literally taking each day as it comes," Apps said.
Sunday's final will be her 26th Test, and a third World Cup title would cap a distinguished international career.
"I'll see how I feel next year and if I'm playing good and get picked then great, and if I don't then that's the way it goes.
"I'll never rule myself out and always try to be the best teammate I can be. I always work hard for my club and whatever happens off the back of that, happens.
"I'll never not put up my hand for a representative jersey.
"But I've got to earn it and I've got to deserve it."
Ali Brigginshaw retired this year with 27 Test caps; only Hall of Famers Karyn Murphy, with 28, and Tahnee Norris, with 33, have more than her.
Apps has also played 50 NRLW games and 16 Origins, the most of any NSW female player.
Her 25th Test was marked by her brother Deon and three nieces visiting camp, while teammates wore "Kezie 25" shirts.
"It was really special my brother said a few words - some of the nicest things he's ever said about me and to me. He must be getting softer in his old age.
"But he has three daughters and knows the significance of what this jersey means and the pathway I've helped forge for the younger generation, like my nieces, to follow through if they choose to."
