The 2017–18 Perth Scorchers Women's season was the third in the team's history. Coached by Lisa Keightley and captained by Elyse Villani, the Scorchers ended the regular season of WBBL03 in third place. They then defeated the Sydney Thunder by 27 runs in a semi-final at Optus Stadium to set up a re-match of the previous year's final against the Sydney Sixers. In the championship decider, held at Adelaide Oval, the Scorchers suffered a heavy nine-wicket loss to once again finish the tournament as runners-up. Squad 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). Personnel changes ahead of the season included: New Zealand marquee Suzie Bates departed the Scorchers, signing with the Adelaide Strikers. Meg Lanning signed with the Scorchers, departing the Melbourne Stars. However, due to a shoulder injury, Lanning would be unavailable for the entire season. New Zealand's Thamsyn Newton was subsequently signed as a marquee replacement player. Due to the departure of Bates (outgoing captain with a 9–7 win–loss record) and the unavailability of Lanning, Elyse Villani assumed the captaincy for the season. England marquee Nat Sciver signed with the Scorchers, departing the Melbourne Stars. Mikayla Hinkley signed with the Scorchers, departing the Sydney Thunder. Changes made during the season included the signing of Taneale Peschel as a local replacement player. Peschel played two games in the absence of Katherine Brunt who was sidelined with a back injury.
