Patterson, born in Kangaroo Island, has been with the Strikers since rebel WBBL|01, and is the third-highest runscorer for the franchise with 1,117 runs.
Patterson, 26, has the equal-most appearances for the Strikers with 71 out of a possible 73, sharing the record with Megan Schutt and Amanda-Jade Wellington.
The dashing right-hander scored 319 runs in WBBL|05, including a match-winning 96-run partnership with captain Suzie Bates which saw off the Brisbane Heat in Mackay.
She was also selected for her favourite team the Adelaide Crows in the Bushfire T20 Showdown in February, and bludgeoned 30 from 12 balls against an attack featuring the likes of Kane Farrell and Connor Rozee.
The match helped raise funds for the State’s bushfire appeal, and shortly afterwards she visited her hometown in KI to help in clinics and support the revival efforts.
Patterson is delighted to remain a Striker.
“I love being at the Strikers which is my hometown team so to speak, and we have continued to build something really special here since it all started,” she said.
“I’ve made a lot of memories here and I’m really looking forward to that continuing for the next three years.”
Patterson joins a flurry of Strikers signings in the last week, with Sarah Coyte, Alex Price, Tegan McPharlin, Ellie Falconer, and Annie O’Neil all confirmed for WBBL|06.
