Central Coast has wasted little time wielding the axe for next season by dumping skipper Noel Spencer less than 12 months after he guided the club to the inaugural A-League grand final.
The Mariners have told midfielder Spencer and defenders Wayne O'Sullivan and Vuko Tomasevic they will not be re-signed after a disappointing end to the season which saw the club lose four of its last five games and miss the finals series.
"We are doing all that we can to ensure that we are a force to be reckoned with next season, and an obvious part of this is reviewing our playing roster and making what we feel to be necessary adjustments," said coach Lawrie McKinna.
"We have identified areas of our squad that need improvement and areas where we are perhaps overstocked. Unfortunately in the world of professional football, releasing existing players is part of that process.
"Sully, Spenny and Vuko have made tremendous contributions to our club during their time here and I'd like to wish them all the best with their future football endeavours."
Spencer, 29, and O'Sullivan, 32, both played key roles in the Mariners stunning surge to the grand final last season, where it lost 1-0 to Sydney FC.
Spencer played 55 games and scored seven goals in his two seasons at the Mariners, while former Irish youth international O'Sullivan played 47.
Tomasevic, 26, joined the club this season and made 11 A-League appearances.
