Moloney initially auditioned for the role of Brett Stark in Neighbours. He did not get the role but later appeared as a one off-character named Cyborg in 1994. He was later recalled to play Jarrod "Toadfish" Rebecchi, brother of established character Kevin "Stonefish" Rebecchi. This was a one-scene role, which aired on 8 February 1995. This became a recurring guest role, and as the character proved popular it became a regular role in 1996. In April 2004 he was nominated for a Golden Rose of Montreux award for Best Actor in a Soap for his work in Neighbours.
