With the series already won thanks to nine-wicket and 37-run victories earlier in the week, Litchfield helped Australia A to a 22-run win in the third and final game at the Gold Coast's Bill Pippen Oval on Monday afternoon.

She finished unbeaten on 16 and helped guide Heather Graham (51 not out) to a half-ton at the back end of their side's innings, the pair combining to add 35 from the last 22 balls and lift the Aussies to 3-151.

Their partnership followed Elyse Villani's player-of-the-game effort from the top of the innings, she bashed out 70 from 56 balls to back up an unbeaten knock of 62 from the Aussies' game one win several days earlier.

Litchfield's Aussies restricted India A to 5-129 - with five separate wicket-takers - to secure the win and series clean-sweep, which also came after they'd scored a 2-1 One-Day International (ODI) series win over their international rivals earlier in the month.

Litchfield was in that squad too but as one of the youngest players in the group she wasn't named in the final XI for any of those games, but picked up valuable experience in an environment surrounded by players gunning to push their selection claims.

The Indians' six-game tour was a ground-breaking, history-making one too, it marked the first time Australia had hosted an international women's A side.

For the hosts the six games shaped as vital selection tools for the Twenty20 and One-Day International World Cups over the next two years, the former in particular.

Leading into the Twenty20 series Australian coach Matthew Mott confirmed there was at least three spots up for grabs in the 2020 World Cup squad, given Meg Lanning's side is ranked No.1 and are the reigning world champions there's no need for a mass turnover.

With that the series looked a golden opportunity for fringe players to push their claims after the Rebel Women's Big Bash League which, of course, was also a heavy focus for the National Selection Panel.

"We've said from day one, the WBBL is very important for T20 selection and pretty much all of those players have performed at some point through this tournament," Mott told cricket.com.au prior to Australia A's Twenty20 series.

"Our top 12 will probably pick themselves and (after that) you look at who are potentially good impact players off the bench who can fill a couple of roles.

"Generally in a T20 World Cup, if you find the right formula in the first couple of games - even though we're playing on some different wickets and different opponents - you're not going to change your team outside of that top 12 or 13 a whole lot.

"All those players (in the A squad) have done well and are in the frame for selection for the World Cup."
