Former St Kilda player Luke Dunstan has joined the Red and Blue as an unrestricted free agent, after selecting Melbourne as his club of choice.

The 26 year-old midfielder has played 116 games and kicked 46 goals across eight seasons.

Melbourne List Manager Tim Lamb said he was excited to add more midfield experience to the playing list.

“We came into this trade period looking to re-stock the midfield area and Luke fits the bill perfectly,” Lamb told Melbourne Media.

“We are really happy that Luke has chosen to make the move to our club.

“With Nathan Jones retiring and Aaron vandenBerg moving on, we have lost a considerable amount of experience out of our midfield group.

“Luke is a proven performer at the highest level and finished this season in exceptional fashion polling 11 votes in the Brownlow Medal.

“We think Luke’s best football is ahead of him and just as importantly, Luke is a terrific cultural fit for our club."

Playing 12 matches this year, the onballer averaged 25 disposals and more than five clearances a game.

Dunstan, who was drafted from Woodville-West Torrens in South Australia, was selected with pick 18 in the 2013 National Draft.
