Despite only previously being able to sign players to single year contracts, WBBL coach Ben Sawyer believes the squad will look familiar for the upcoming season once the Club can begin signing players again.
The Sixers will be the defending Champions in WBBL|03 after beating the Perth Scorchers at the WACA in the WBBL|02 Final, but with the retirement of legend Lisa Sthalekar changes to the squad will be necessary.
"Obviously with Lisa retiring there's definitely one spot we've got to make up," said Sawyer.
"We would really hope to keep the majority of the squad [from WBBL|02]. I think everybody enjoyed themselves, so I think they will all want to come back, hopefully!
"Once that MOU is sorted, I think the advent this year is there might be multiple year contracts so that would make the group a lot more stable and looking to reward the players that did really well for us last year."
In WBBL|02 the Sixers, through openers Alyssa Healy and Ellyse Perry, were able to take games away from teams with their strong top order batting.
For next season, Sawyer is aiming to strengthen that area of the squad with another potential top order batter.
"I think we would really like another top order bat," said Sawyer. "Our top order did a great job for us last year, but you can always improve.
"I think another batter would just give us that ability to go even harder and attack even more, which is what we're after."
With players like WBBL|02 Young Gun and all-rounder Ashleigh Gardner dominating during the previous summer, Sawyer said he also learnt a key lesson about Twenty20 cricket.
"I think the one other thing I've learnt through out the Big Bash is that all-rounders are amazingly valuable," said Sawyer.
"Any player that we look for, we'd look for somebody that can ... definitely bat and bowl because the more options you have, the better off you are."
Four Sixers players from the first two seasons are currently in England playing for Australia in the 2017 Women's World Cup, while another two (Dane Van Niekerk and Marizanne Kapp) are playing for South Africa.
Sarah Aley made her international debut against Pakistan last week and Perry has found some excellent form with the bat. Wicket-keeper Healy has played a strong batting role lower down the order and Gardner is taking wickets and showing-off her powerhouse batting.
