Late on Friday afternoon, the Mariners announced 24 year-old Anderson would depart the club when his contract expires on 30 May.
The latest quintet of talent join Matt Simon, Brent Griffiths and Travis Major on the unwanted list for next season.
Anderson joined the Mariners in 2012 from Gold Coast United and made 67 appearances for Central Coast, including a role in the 2012-2013 Championship winning season.
Cernak joined Central Coast - his sixth A-League club, a record - in February 2013 and played 18 times for the Mariners this season.
The 26 year-old midfielder made 12 starts, with the majority of those after Walmsley was appointed interim coach in place of the sacked Phil Moss, and scored once.
Defender Morton is a Mariners National Youth League product and after making his debut in the club’s Championship winning season he started three times late in the 2014-2015 campaign.
Slater, the 18 year-old son of former Socceroos winger Robbie, exits by mutual consent after one A-League game in two season.
Pandurevic, 18, was released early and will return to Manly United for the club’s NSW Premier League season.
The news arrives on the first official day of Tony Walmsley's time in charge as full-time coach.
With long-serving captain John Hutchinson having retired after 10 seasons at the club, the Mariners are poised for a fresh look heading in to the 20015-2016 campaign.
