The former Lion and Eagle made her way to West Lakes the long way after both a season in the SANFLW and an uncertain pre-season as a train-on prospect.
The left-footer was said to have impressed during the Crows' training program, and with known scoring capabilities, the 21-year-old will offer head coach Matthew Clarke another avenue to goal this summer.
“McKenzie reads the play well and can break the lines with her long kick,” Adelaide's Head of Women’s Football Phil Harper said of the forward.
“She kicked a goal in our internal trial and looked dangerous whenever she wheeled onto her left foot.
“She’s made the big move over from WA and has been working hard to get to where she wants to be.
“McKenzie has experience at AFLW level and we think she can help make us better as a team this season.”
The Western Australian's opportunity at her third club in four seasons arose after dual premiership defender Deni Varnhagen was placed on Adelaide's inactive list in November due to her public opposition towards mandatory vaccination.
Dowrick and the Crows are set to commence their season when they face reigning premiers Brisbane on Sunday afternoon in promises to be a mouthwatering grand final rematch.
