Geelong star Georgie Prespakis will attempt to focus her attention on a breakthrough AFLW finals win for the Cats instead of engaging in banter with her elder sister Madison.
The Prespakis siblings, key midfielders for their respective clubs, will face off in Sunday's elimination final as Essendon travel down to GMHBA Stadium.
Madison, a four-time best-and-fairest winner with Carlton and the Bombers, tagged her sister in a social media post confirming the AFLW's finals fixture.
But Georgie didn't bite back.
"I sent (Madison) a message last night," the 20-year-old Cats star said.
"I just want her to enjoy the week of the build-up of the final, but as for my week, my 100 per cent full attention is with Geelong and doing what we can to get the win.
"We're pretty confident in whoever we come up against.
"It will be a really good game, we're just really stoked we've got a home ground advantage."
Geelong are eyeing a first post-season win in their AFLW history, after falling just short against North Melbourne in the corresponding match last season.
Essendon got the better of the Cats earlier in this campaign, with the Bombers surging into finals in just their second season as an expansion club.
Geelong finished off their home-and-away fixtures with a convincing win over Hawthorn on Saturday, with Georgie Prespakis resting in the final quarter having already racked up 35 disposals.
"We're not ready to be done yet - hopefully it will be next week and the week after that we're continuing to be coming back to train and be around our teammates and coaches," she said.
"We've really hit our straps the last few weeks.
"We want to play with freedom, and the past two games we have been able to play eight consistent quarters.
"To be able to win games you have to be strong across the entire match."
The Bombers women are striving to become the club's first team to win a final in more than 7000 days, with Essendon's AFL side not having tasted post-season success since September 2004.
