Each 2020–21 squad was made up of 15 active players. Teams could sign up to five 'marquee players', with a maximum of three of those from overseas. Marquees are classed as any overseas player, or a local player who holds a Cricket Australia national contract at the start of the WBBL|06 signing period.[2]
Personnel changes made ahead of the season included:
Naomi Stalenberg signed with the Hurricanes, departing the Sydney Thunder.[6]
New Zealand's Hayley Jensen was added to the Hurricanes squad as a marquee replacement player after Tayla Vlaeminck was ruled out of the season through injury. However, Jensen would still only be eligible to play in the place of a fellow overseas marquee player, if or when required.[6][7]
Erica Kershaw signed with the Hurricanes, departing the Melbourne Renegades.[6]
