Victorian Amateur Football Association jet Tom Sullivan headlines the additions with the former St Bernard's player expected to slot into the Seagulls' midfield.

Experienced defender James Imbi crosses from South West District league club Heywood and ruckman Dougal Hamilton joins from Geelong Grammar.

Seagulls president Noel Black said the club, which finished third in 2018 after falling to Koroit in a rain and wind-affected preliminary final, was thrilled with the recruiting drive, which comes three weeks out from the season.

"Tom is handy from what we're hearing. He's a midfielder and he's very athletic," he said.

"I do hear he's a very, very talented player. He's moving down in two or three weeks.

"I had a brief chat to him last night.

"James Imbi is (assistant coach) Winis' brother and he's in the twilight of his career but he's still a very, very handy footballer."

Sullivan will ease the burden on coach Dan Nicholson, Kaine Mercovich and Matt Pitt in the Seagulls' engine room.

The Hampden league kicks off on April 6.
