Oliver arrives in Erinsborough after finding out about his brother's lies and he explains to Carmella that Sebastian has lied to everyone. Oliver and Carmella Cammeniti (Natalie Blair) grow closer and they begin a relationship, but Paul believes that Oliver would be a better match for his daughter Elle. Paul blackmails Ned Parker into helping him split Oliver and Carmella up, but Ned's plan doesn't work after Oliver stays with Carmella. When Carmella is asked to take over her family business to save it from being run into the ground by her uncle, Raimondo (Jeff Kovski), Oliver tries to help her financially. However, he is told that he cannot get his inheritance. Carmella eventually comes up with the money and the couple set up a fruit and vegetable business. When Carmella realises that her uncle has not forgiven her for giving away his daughter's child, the business soon runs into trouble. Carmella realises that she has to play Ray at his own game and Oliver grows uncomfortable when he witnesses Carmella's ruthless streak. Paul and Elle take a chance to make more trouble and decide to force Carmella and Oliver apart. They plant a bomb in Carmella's delivery van, making it look like Ray has done it, but the bomb detonates at the wrong time nearly killing Oliver and Carmella. When Carmella confronts Ray, he has a heart attack and Oliver, who witnesses the scene, breaks up with Carmella. When Ned tells Elle about being blackmailed by Paul, Elle and Oliver decide to bring him down. Paul is very happy when Oliver finally manages to sign documents entitling him to his inheritance, but during the document signing, Alan Napier (Barry Friedlander), an assistant to the Barnes family, suddenly collapses. At the hospital, Alan falls into a coma and as Oliver waits for news, he and Elle decide to continue with their plan and announce their engagement. Paul believes that he will now have access to Oliver's inheritance and sells Oliver his shares in Lassiters to be able to get Janelle Timmins' (Nell Feeney) half. Elle and Oliver then publicly declare that they now have full control of the company and Paul is left with nothing. Oliver then begins a relationship with Elle.
