Both long-time cast members, Moloney and Bonner have shared many storylines on the show as Toadfish and Steph.
Moloney is returning to filming after his stint in the UK in the Celebrity Big Brother house.
Bonner, who left Neighbours in 2010, returns to Ramsay Street as Steph Scully who is released from prison.
Moloney recently told Digital Spy of the storylines the pair are sharing: "[Steph] is a little upset with how Toadie represented her, and has a bit of a go at Toadie about that!
"Toadie normally has a history of just dropping whatever he's doing for Steph, so it should be a little bit interesting!"
