MELBOURNE's AFL pre-season is officially underway with first-to-fourth year Demons and a host of senior early-starters returning to the track on Monday.

All four of the club's new recruits were on display as Brodie Grundy, Lachie Hunter, Josh Schache and Kyah Farris-White took to Gosch's Paddock.

Senior names such as Petracca, McDonald, Salem, Viney, May and Fritsch all fronted up a week ahead of schedule to get a head start on the opposition.

The full squad will be back on deck next Monday on December 5.
