In October 2013, Caravella agreed to another extension with the Jets, securing a future with the club until the completion of the 2014/15 season.
In June 2014, it was unexpectedly announced that Zenon Caravella had requested a release from the remaining year of his Jets contract, citing business opportunities as the reason for his exit.

After a tumultuous season with Newcastle Jets under Nathan Tinkler - which saw 5 players sensationally sacked mid-season - Caravella was offered the captain's armband and refused on principle and loyalty to his exiled teammates.
