Williamstown has extended the contracts of 30 players who helped the club reach the second-last week of the VFL season.
The Seagulls went on a recruiting spree towards the end of 2013, necessitated by the split with AFL club Western Bulldogs.
The big names to commit for 2015 include captain Ben Jolley, Adam Marcon, Ed Carr, Scott Clouston, Brad Mangan, Kane Lambert, Willie Wheeler and Nick Meese.
Rising stars signed up include Dylan Conway, Jake Owen, Ben Bese, Michael Gibbons, Jack Dorgan and Sam Critchley.
“We’re delighted to have so many players commit for 2015,” Seagulls football manager Chris Dixon said.
“It’s a great show of faith in the direction we’re heading as we aim to improve in 2015.”
