St Kilda are on the brink of moving home to Moorabbin, but the AFL has made a point to them that everything must be organised when they do so.

In 2010 the Saints relocated to Seaford but after that move failed, they have decided to redevelop their old home in Moorabbin and will be moving back there in time for the start of this season.

The club and fans are celebrating the move back to where the called home for almost 50 years, but the AFL is mostly concerned about the Saints' financial situation as they are one of three clubs with the highest debt in the AFL.

"St Kilda have dealt with a whole series of challenges, but it's incumbent on them now to get their P and L (profit and loss) working," AFL CEO Gillion McLachlan said.

"They have to get their business to work now."

St Kilda are also facing heavy on field expectations now that they have a young and well-balanced yet haven’t made the finals since 2011.

McLachlan revealed that overall AFL clubs are doing well financially, reducing their overall debt to 50 millions dollars, down by 10 million from last year.
