KEY DEFENDER Sam Frost is off to Waverley, after Melbourne completed a complicated trade with Hawthorn.

The Demons traded Frost, picks No. 42, 61 and a future fourth-rounder in exchange for pick No.50 and a future second-round selection. 

Hawthorn will be Frost's third club, after 21 matches at Greater Western Sydney (from 2012-14) and 70 at the Demons (2015-19). 

The 26-year-old was originally selected with pick 1 in the 2012 NAB AFL Rookie Draft from under-18 side Sandringham Dragons.

He played all 22 games this season, averaging 13 disposals and four marks a match. 

Hawthorn football boss Graham Wright said Frost’s versatility was a selling point. 

"Sam is a fierce competitor and has excellent speed and agility, which allows him to play on tall and small opponents," Wright said. 

"Sam will complement our defensive unit extremely well. We are excited to see what Sam can bring to the Hawks."

"We were not in the position to offer Sam a long-term contract, so we were comfortable with him exploring his options and we’re pleased he has found a position at Hawthorn," Melbourne footy operations manager Josh Mahoney told

"It’s always disappointing to see any player leave, but we think Sam will benefit from the move and we are confident in our backline.

"In recent years we’ve brought in the likes of Jake Lever and Steven May, and we have a lot of young depth in defence that will benefit from more responsibility."
