Not surpringly, much of Gold Coast's review of Saturday night's heartbreaking loss to Melbourne focused on the final minute of the game.

A Nick Holman goal gave the SUNS a six-point lead with 48 seconds remaining, but the Demons managed a goal and behind from two centre bounces to pinch an unlikely victory.

Emerging midfielder Darcy Macpherson said Gold Coast had not executed its "ice-the-game" setup as it should have.

"It's on all of us, coaches and players, that we should have refreshed our brains with the structure, but we didn't," MacPherson said.

"From now on, we know what we need to do, and we addressed that."

From the stoppage following Holman's goal, the SUNS wanted an extra man in defence, which they executed with Jack Martin rolling back to help out in the defensive 50, but something was lost in communication further afield as Melbourne half-back Marty Hore found himself in too much space to kick the match-levelling goal from 50m.

Macpherson said communication between the lines had been a major talking point in the review.

"We just need to be switched on after a goal's been kicked," he said.

"Holman kicked his goal and we were celebrating that, and it left us a bit short to get our heads around saving the game.

"We need to be switched on, knowing our roles and where we need to be for the centre bounce."

At Wednesday's light training session, coach Stuart Dew stopped one drill to reinforce the importance of communication, bellowing at the top of his voice that he wanted to hear players demanding the ball.

The SUNS have played in five games decided by less than a goal in 2019 and Macpherson said they were confident of executing if Sunday's game against Port Adelaide resulted in a similar scenario.

Brayden Fiorini, who missed last week's game with a knee niggle, trained strongly and should be available, while running defender Pearce Hanley is likely to miss after suffering a badly corked quad.
