"Kim Garth and Heather Graham have performed strongly at domestic level over the past 12 months, and both thoroughly deserve their spot on the list," national selector Shawn Flegler said.

"Phoebe Litchfield is a young talent who we believe has a big future, she's built her game upon a very sound technique and we're confident she can transfer those skills into international cricket.

"We've had a core group of players performing well over the last 12 months which means some talented players have missed out, it's certainly made selection tough but we're in a fortunate position to have such depth across Australian Cricket.

"Importantly, there is still the opportunity for players not offered contracts to earn upgrades through consistent performances, as we saw with Grace last year."

"Nicola expressed a desire to spend the winter in Tasmania to allow her to utilise a full preseason at home, focusing on using that time to develop skills in her game to push for international selection in the future," Flegler said.

"We offered Nic a contract because we believe she is a player of international quality, but we respect her decision to focus on a pre-season program with Tasmania and will continue to support her moving forward."

Australia's next cricket is the multi-format Ashes tour which begins in mid-June. The players will have various camps in Brisbane during May to prepare.

The next 12 months has three Tests in Australia's calendar with away matches against England and India plus a home fixture against South Africa early next year.

Australia women central contracts Darcie Brown, Ashleigh Gardner, Kim Garth, Heather Graham, Grace Harris, Alyssa Healy, Jess Jonassen, Alana King, Meg Lanning, Phoebe Litchfield, Tahlia McGrath, Beth Mooney, Ellyse Perry, Megan Schutt, Annabel Sutherland, Tayla Vlaeminck, Georgia Wareham
