Daniel Millynn, Jedd Gvozdenovic and Jarrod Herzina all featured in the club's 2011, 2013 and 2014 AWFA cup triumphs and have committed to a return.

Millynn is set to take on a playing assistant role under recently-appointed senior coach Daniel Griffin.

Diamonds have also secured the services of Dylan Mountain, who has moved to the Border from Queensland with the army, having had previous NPL experience on the Sunshine Coast.

"We're obviously working towards bringing in a few new recruits, probably the lack of depth last year was what really cost us," Griffin said.

"We had to push a few younger guys up into the seniors earlier than we would have liked.

"The aim next year is to take that back a bit, bring in guys with senior experience and give the young guys that gradual exposure.

"We're certainly looking to strengthen across the board, we're looking at bringing in not only senior players, but squad players that will push senior players."

Griffin believes the club is building after a tumultuous 2019 off-season which essentially saw the entire Diamonds starting lineup depart to rival outfits.

"Having those three back is huge because they've won three or four cups each in seniors and they bring a lot of experience," Griffin said.
