The BIG call has happened too.
Australia have left all-rounder Ellyse Perry out.
Perry is considered one of - if not - the best women's player in the world, but T20 cricket is arguably her weakest format.
In the last two years, Perry has scored just 152 runs at a strike-rate (runs per 100 balls) of 103.40 and in this season's WBBL her strike-rate was 91.32.
Before the series, national selector Shawn Flegler said: "She's played for Australia for a long time and is highly experienced, but we always want our players to develop and evolve, and Ellyse is no different."

We'll bring you the full teams shortly, but I can tell you that Australia have handed a debut to leg-spinner Alana King.
King's helped Perth Scorchers to the Women's Big Bash League win in 2021, taking 16 wickets at an economy rate of just 5.82.

Time for the toss...
What's the schedule?published at 07:38 Greenwich Mean Time 20 January 2022
Well, first of all, we're all here a week earlier than we were due to be.
The series was due to start with the Test on 27 January before the three one-day internationals and three T20s.
However due to the 10-day quarantine period that both sides will have to go through when they travel to New Zealand for the 50-over World Cup, that starts on 4 March, the series has been brought forward.
We start with the T20s before the Test stays in the original slot and then we finish with three ODIs. Let's hope they have something riding on them.

The Women's Ashes is slightly different to the men's equivalent because it is a multi-format points-based series instead.
A win in the four-day Test is worth four points, while both sides will take two points apiece if it is draw. That has been the case in three of the five Ashes series since the format was introduced.
There are three ODIs and three T20s, with each of the white-ball games worth two points for a win, an one for a tie or no result.
It means 16 points are available in total, and it has always taken at least 10 to win it.
The format can lead to a really exciting series and make every single game count.

The Men's Ashes were an absolute disaster if you were an England fan.
Now it is the turn of the women.
Can they upset the best team in the world and grab the Ashes back?
The start of almost three weeks of top-class cricket is here. Let's get started.
