Ryan Burton and Jeremy Finlayson among five players delisted by the Power.
With new coach Josh Carr officially taking the reins after Ken Hinkley's departure, Burton and Finlayson have been informed they will not be offered new deals, while Dylan Williams, Lachie Charleson and Hugh Jackson have also been let go.
"Ryan and Jeremy have both, at times, played important roles for our AFL side, offering versatility and depth when we've required it," list manager Jason Cripps said.
"Dylan and Hugh showed some positive development over the past few years, with both earning opportunities at the top level, while Lachie was a solid contributor to our SANFL program and showed great commitment to the club in his two years on the list.
"We wish all five players the very best for their futures."
