MELBOURNE has struck a deal with the City of Casey and the Casey Scorpions that will give the club a suburban 'home' ground at Casey Fields for the next 30 years.

The deal, which was months in the making, was ratified by the council on Tuesday and includes a $2.1 million upgrade to Casey Fields, which the Demons will use as a summer training base as well as for one training session a week during the AFL season.

"We're really going to be able to come in here and make this place our home away from home," club president Jim Stynes said at the announcement of the agreement at Casey Fields on Friday.

"We'll consider it like a campus of a university where our guys will be coming every week for the next 30 years and beyond.

"We're just going to have the best of everything. The great thing is we're going from the worst facilities in the AFL to potentially just about the best. This time next year we are going to have the best facilities in the AFL, which is just amazing.

"I think it's also important to stress that it's not just a training ground for us. It's also opportunity to engage with people in the community. We've already started to engage with schools and local football clubs."  

The upgrade which will include a new gym, medical rooms, offices and change rooms, will be jointly funded by the three parties bound by the agreement along with the AFL and state government.

Former Melbourne star and media personality Garry Lyon is the ambassador for the partnership and he was delighted that the current crop of players would not have to face the same pitfalls associated with the itinerant existence that he and his teammates endured.

"We moved from the MCG in 1985 and from that point forward we've had no base as a football club, and it's been a disgrace and a farce," Lyon said.

"As the competition has fast-tracked itself into this professional era that we find ourselves in, our club, and by extension our footballers, have been carrying this massive load around their necks for the best part of 25 years because they had no home.

"The thing that always struck me as being inconceivable is that we were failing to provide these blokes with the best possible facilities.

"These blokes will come to work now with the absolute best facilities at their disposal and that's what this football club deserves."

City of Casey mayor Geoff Ablett was proud to have signed off on the agreement.

"The partnership will provide many significant long-term benefits for the Casey community, including a commitment by Melbourne Football Club to deliver a comprehensive community partnership program for the next 30 years," Ablett said.

The Demons will also move into new head office facilities in the shared Olympic Park project in Melbourne next year.
