The Irish striker and Australian goalkeeper are on their way to pastures new in the A-League after their contracts expire at the end of May
Central Coast Mariners have confirmed Roy O'Donovan and Paul Izzo will leave the club, with Newcastle Jets and Adelaide United set to benefit.
The Jets subsequently unveiled O'Donovan as a new recruit, while Izzo has been linked with a return to Adelaide over the past few months.
Speaking about crossing the F3 Derby divide, O'Donovan said in a statement: "Obviously the Jets are transitioning between managers and there are a lot of players out of contract, but if we can get the right type of creative players in the team then I sense that we will be able to push on.
