2017–18 Sydney Sixers WBBL season

Each WBBL|03 squad featured 15 active players, with an allowance of up to five marquee signings including a maximum of three from overseas. Australian marquees were defined as players who made at least ten limited-overs appearances for the national team in the three years prior to the cut-off date (24 April 2017).[3][4]

Personnel changes for the Sixers ahead of the season included:

• Lisa Sthalekar retired at the conclusion of WBBL|02.[3]
• Rhiannon Dick departed the team and subsequently joined the Adelaide Strikers.[5]
• Erin Burns joined the team after departing the Hobart Hurricanes.[6]
• Lauren Cheatle signed a three-year contract with the team, departing the Sydney Thunder.[7] However, she would miss the entire season due to a back stress fracture injury.[8][9]

The backend of the tournament was notable for the comeback of medium-pace bowler Sarah Coyte, who had previously played for the Adelaide Strikers until retiring at the conclusion of WBBL|02.[10] With South African marquee players Marizanne Kapp and Dane van Niekerk unavailable for the climax of the competition, coach Ben Sawyer approached Coyte—who had been playing cricket for her local club Penrith occasionally during the summer—about signing for the Sixers as a replacement player.[11] Upon returning to the league, she delivered "exemplary bowling"[12] performances to claim ten wickets at an average of 8.10 in four matches.[13]

England marquee Amy Jones also signed as a replacement player for the Sixers, having performed a similar role for the team during WBBL|02.[14]

The table below lists the Sixers players and their key stats (including runs scored, batting strike rate, wickets taken, economy rate, catches and stumpings) for the season.[13]
