The 32-year-old local legend, who won an A-League premiership with the Mariners in 2008, is off contract after three seasons and two premierships, a championship and an FFA Cup with Sydney FC.
He made 67 A-League appearances for the Sky Blues - 54 of which were off the bench - scoring five goals.
But it’s his physical presence and ability to intimidate defenses which has prompted new coach Mike Mulvey - who last week snared fellow attacker Corey Gameiro - to bring Simon back to his roots.
He struck 41 goals in 107 games for Central Coast over six seasons, making himself a folk hero among fans - and the highest scorer in the club’s history.
While Simon is on his way in as part of a post-season clearing of the decks at Sydney FC, promising midfielder Lachlan Wales is on his way to Melbourne City.
The highly regarded Mariners junior, 20, made 10 A-League appearances for the wooden spooners this season and the club fought hard to keep him with the offer of his first senior contract.

But the lure of Melbourne City - also hot favourites to snatch fellow Mariner Daniel De Silva - proved irresistible for the off-contract youngster.
The Mariners declined to comment when contacted by The World Game.
