The AFL on Tuesday night announced its compensation for the four clubs - the Demons, Western Bulldogs, Adelaide and Fremantle - who have lost players to the new franchise so far.
The League determined that Melbourne's compensation package for Scully, based mainly on the size of the contract offered by the Giants, fitted within the first band.
They'll get one first-round pick, which can be activated after the club's first selection in any draft between 2012 and 2015, and one mid-first-round pick that, when activated, will be placed in the draft behind the clubs who missed that year's finals.
The Bulldogs will receive second-band compensation, one first-round selection, for the loss of Callan Ward, as will the Crows for Phil Davis.
Rhys Palmer's departure from Fremantle has been deemed worthy of third-band compensation, an end of first-round pick.
"There was a significant differential in the contract offer to Scully to those of Ward and Davis, and it was therefore determined that the compensation package for Melbourne should be in the highest band," an AFL statement said.
"Ward and Davis were each confirmed as a higher compensation package to that offered to Fremantle for the loss of player Palmer, again on the basis that there was a significant differential in the contract offers to Ward/Davis and that of Palmer."
The ruling means Melbourne will get the same for Scully as Geelong received when Gary Ablett moved to Gold Coast at the end of last year.
