ST KILDA players and coaches will help fund the $2.4 million shortfall as part of the fundraising campaign for the redevelopment of the club's spiritual home in Moorabbin.
Construction at the Linton Street venue begins next week.
The Saints moved from Moorabbin to Seaford in 2010, with the new venue causing discontent among players due partly to its long distance from Melbourne.
After a video about the return was shown at the club's season launch on Friday at the Moorabbin Town Hall, coach Alan Richardson told the crowd of Saints supporters the players were excited to return to the venue which will be known as RSEA Park, after RSEA Safety was announced as the naming rights sponsor.
"With respect to Moorabbin, it means a lot to our players. 'Rooey' (Nick Riewoldt) and myself were up in front of the group. (CEO) Matt (Finnis) presented that video to the players and when they finished poking fun at their teammates that were in the video, it had a similar effect on them … and that is what a fantastic opportunity it is to go back home," Richardson said.
"Players will certainly financially commit to the cause. So will the coaches.
"We know the St Kilda Football Club has given us an opportunity to do what we love doing and we think it's the right thing for us.
"It's such an important moment for our footy club in its history to give back, so we'll certainly be doing that."
St Kilda has raised $27.6 million for the redevelopment and is calling on its fans to help make up the rest of the money required.
Finnis said the shift was necessary in the club's bid to add to its sole 1966 premiership.
"Next week, we commence construction of our new training, administration and community facility just down the road," Finnis said.
"There are very few things that are more important to our future success right now, both on and off the field, than returning our great club back to Moorabbin. Strategically, but also emotionally, it has the potential to transport our club to galvanise support like never before."
