2019–20 Sydney Sixers WBBL season

The 2019–20 Sydney Sixers Women's season was the fifth in the team's history. Coached by Ben Sawyer, they finished fifth in WBBL|05. The Sixers entered the tournament as "hot favourites"  and proceeded to win six of their first eight matches. However, after captain Ellyse Perry sustained a shoulder injury, they lost five consecutive games to miss out on qualifying for finals for the first time.

Squad
Each 2019–20 squad featured 15 active players, with an allowance of up to five marquee signings including a maximum of three from overseas. Australian marquees are players who held a national women's team contract at the time of signing on for their WBBL|05 team.

South African Marizanne Kapp returned for the Sixers to become one of only two foreigners, along with New Zealander Sophie Devine (member of the Adelaide Strikers), to play in each of the first five WBBL seasons with one team.

On 19 November, the Sixers announced the signing of Englishwoman Hollie Armitage, replacing captain Ellyse Perry who would miss five games due to a shoulder injury. Alyssa Healy stood in as acting captain in the absence of Perry.

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.
