Cooper, 31, is a best and fairest winner with Howlong and was also named in its team of the decade in 2010 and will add another dimension to the Demons attack.

After losing the preliminary final against Bullioh last year, Corryong has emerged as the off-season pacesetter after also snaring the prized signatures of James Paton (Culcairn), Adrian Rijnbeek (Howlong) and Shannon Gilson (Thurgoona).

The arrival of Cooper caps a productive off-season and has many pundits predicting the Demons as the team to beat this season.

“We targeted four players that we wanted over the summer and to be able to land all four of them is satisfying,” Demons coach Andrew Reid said.

“A lot of people have installed us as flag favourites but we are under no illusion that we have got a lot of hard work to do.”
