Australia is just one win away from completing their most dominant Women's Ashes performance in recent memory.
The Aussies will look to continue their unbeaten run in final T20I in Bristol on Wednesday (local time).
The first multi-format Ashes begun in 2013 but so far no team has gone through undefeated with the biggest results being recorded by England in the inaugural Ashes.
Coming into the series, Australian wicketkeeper Alyssa Healy jokingly said that the side “go through the series undefeated” when asked to make a prediction ahead of the Ashes last month.
"I know Alyssa Healy jokingly said that we could potentially go undefeated this series, but for it to actually be on the cards is something not only myself but a lot of the girls didn't think would unfold," Australia allrounder Jess Jonassen told media on Tuesday.
"But we're really pleased with the cricket we've played.
"It would be really special, it's something we've spoken about in terms of finishing off series' well as a group.
"To be able to hopefully go through undefeated would be really special, there's been some quality sides over the years that have managed to do that, so to be one of those would be pretty special."
If Australia wins in Bristol, it wouldn't be the first time a women's team have gone on an English tour undefeated. In 1998 and against in 2001, Belinda Clark led Australia to an unbeaten tour.
