The captain emphasized that record-breaking attendance figures throughout this tournament reflect the rising status of women's athletics.
"Tomorrow's game will show that.
We know it's been a big deal, obviously we don't really know how it's looked or felt from the outside but certainly to play in it and to be part of the record-breaking crowds and some exciting games, yeah we have felt that [importance]," Sciver-Brunt said.
Dismissing the impact of previous defeats against Australia, including a multi-format sweep 18 months ago, Sciver-Brunt stated that the squad has moved forward.
"Our team has come a long way since that Ashes tour," she said.
She stressed that the magnitude of playing a home championship match at the historic venue supersedes past rivalries.
"I think everyone knows what tomorrow is about, a World Cup final at home at Lord's, the occasion is already massive," Sciver-Brunt said.
Sciver-Brunt further explained that the squad is entirely focused on the upcoming match rather than looking back at historical statistical deficits.

"There's not really been any talk about the Ashes or proving people wrong from that," she said.
The England leader revealed that a conversation with her wife and former teammate put the cultural significance of the upcoming final into perspective.
"It's bigger than you think it is," Katherine Sciver-Brunt, former England cricketer, said.
The captain recalled using strategies from their successful 2017 campaign to keep the current squad grounded and focused on the moment.
