Blease played 33 matches and kicked 25 goals after being plucked as a 17-year-old with selection No.17 in the 2008 NAB AFL Draft.
Despite his inability to cement a game with Melbourne, the talented Blease is likely to attract interest with his pace and ability to run and carry the ball.
Demons football manager Josh Mahoney told AFL.com.au the club wished Blease all the best after six seasons with the club.
"When we met with Sam during his end-of-season exit interview, we both agreed that it hadn’t worked for him at the Melbourne Football Club and that we would try and assist to find him a new club during the trade period," Mahoney said.

Drafted in 2008 as a priority pick after the first round, Blease did not make his debut until 2011 after suffering a broken ankle in a schoolyard accident in 2009, with the incident setting him back significantly.
However he was good enough to earn two Brownlow votes in just his fourth game when he tore Gold Coast apart on the MCG.
The speedy wingman/forward looked to be consolidating that promising start late in 2012 when he put in a series of exciting performances including a five-goal haul against St Kilda in round 20, which earned him a Brownlow vote.

He signed a two-year contract at the end of that season, committing to the club under former coach Mark Neeld and continuing to work on his endurance.
He then suffered an ankle injury in the NAB Cup of 2013, which set his season adrift and he played just 10 games before having post-season surgery.
Despite solid form in 15 VFL matches this year, he played just two senior games under Paul Roos (his fifth senior coach at Melbourne), with the highlight being his two-bounce running goal against Port Adelaide in round 18.
However he was dropped after a poor performance the following week against the Brisbane Lions and ended the season in the VFL.
Blease was good enough to be twice nominated for the NAB AFL Rising Star Award but he played in just six wins in his six seasons with the club.
