Michelle tries to befriend Matt and offers him a dress from surplus stock for his wife. She later calls her boss, Dennis Dimato, to tell him that getting Matt onside will not be hard.

Michelle later turns up at Paige's house, claiming that Dimato found her and attacked her.

I feel like I've arrived at the perfect time."^[9] Tyler is the younger brother of established character Mark Brennan (Scott McGregor).^[8] Burns felt an instant connection with McGregor, as they had previously met a few times through their modelling agency, which he felt helped him secure the role.^[9] Tyler is a mechanic and was billed as a "badboy-with-a-heart".^[9] Melissa Field from TV Week Soap Extra also called him "troublesome" and a "ladies' man".^[9]

He just wants to come home."^[12] Nick befriended Georgia Brooks (Saskia Hampele), causing her husband, Kyle Canning (Chris Milligan), to dislike him.^[12] Fotiou later described Nick: "He is a very interesting character. His intentions are certainly noble, however all is not what it appears and I love the way the story unfolds – there's a lot of surprises."^[10] Fotiou had to undergo a small makeover for the part, which involved having his curly hair slicked back to create "a more conservative appearance."^[10]

During a function at Paul's penthouse, Chris Pappas (James Mason) chokes on some food and Georgia saves his life. When Nick questions Georgia as to why she did call for his help, she calls him arrogant. Nick makes a bet with Paul that he can have sex with Georgia, even though she is married. Nick gets closer to Georgia when he asks for her help with fundraising ideas. He gives her tickets to the ballet as a gesture of thanks and accompanies her when her husband is busy with work. Nick later asks Georgia to a conference in Hobart, but Georgia overhears him talking about the bet with Paul. He tries to pass it off as a joke, but Georgia pours her drink over him, causing Nick's stutter to return. Paul angers Nick when he informs him that his application for a cancer research centre has been denied. Nick doctors Paul's blood test results and tells Paul that he has leukaemia. Nick begins Paul on a course of chemotherapy.

Paul tells Nick that he is willing to back his plans for the treatment centre, after the sale of the site does not go through. Nick tries apologising to Georgia again, but she makes a complaint against him. She is suspended from work after she accuses Nick of framing her by hacking into her social media page to reveal a patient's details. When Nick learns the decision about the research centre has been delayed, he tells Paul that his body has stopped responding to the chemotherapy. Paul later informs Nick that the cancer centre has the go-ahead. Nick finds Georgia in his hotel room and believes she has been going through his computer. She is arrested and later fired from the hospital. Paul collapses at The Waterhole and Nick is prevented from treating him in private. Georgia confronts Nick and claims that he has faked Paul's illness. Georgia takes the evidence to Mark Brennan (Scott McGregor), who questions both Nick and Paul. Nick is suspended when IT find out that he deleted Paul's patient files. He confesses what he did to Terese, claiming his motivation was to find a cure for cancer. He then attempts to flee Erinsborough, but Brad calls the police and Nick is arrested. Paul asks to see him and tells him that the research centre will be shut down and he will see to it that Nick loses his medical license. At the station, Nick belittles his family, before he is led away.

Two years later, Terese's fiancé Gary Canning (Damien Richardson) visits Nick in prison. He tells Nick that Terese has been diagnosed with breast cancer and that her current treatment is not working, before asking him for his help. Terese also visits Nick and he recommends immunotherapy, but tells her he has to get out of prison in order to help. Terese agrees to talk at his parole hearing, while Clive Gibbons (Geoff Paine), the hospital's COO writes a letter of recommendation. Paul also comes to see Nick to let him know that he will do everything he can to stop his release. However, Nick is paroled under the condition that does not practice medicine, but he can continue his research and oversee Terese's treatment. Nick is reacquainted with his niece Piper Willis (Mavournee Hazel), while David Tanaka (Takaya Honda) is assigned to oversee Nick's work. While attending church, Nick helps Amy Williams (Zoe Cramond) when she sprains her ankle. Nick soon learns Amy is Paul's daughter and attempts to speak to her, but Leo Tanaka (Tim Kano) tells him to stay away. The West Waratah Star publishes an article about Nick's employment at the hospital and the hospital board threatens to reverse the decision to let Nick consult on Terese's treatment. A further article painting Nick in a more favourable light is later published.

Gary overhears Nick on the phone admitting to keeping something from Terese, before putting a file in his briefcase. Amy invites Nick to the penthouse for a drink. He later realises she has taken his file. Amy refuses to hand it over until he tells her the truth. Nick says he wants to help Terese and attempts to take the file from Amy, who hits him with a vase. Amy learns that Nick wants to open a wellness centre for cancer patients, and she apologises to him. They later spend the night together, and she comforts him when a young patient dies. Stephanie Scully (Carla Bonner) offers up Robinsons Motel as the location for the wellness centre. Paul tries to write Nick a cheque for any amount, as long as Nick leaves town and opens his wellness centre in Perth, but Nick refuses the money. As Nick is spending time with Amy and Terese, Mark Brennan comes to search his room after receiving a tip off that Nick has taken cancer drugs from the hospital. Mark finds the drugs and Nick accuses Paul of planting them. A patient comes to Nick's hotel room claiming that Nick texted her to pick up the drugs. Mark finds the sent text on Nick's phone and takes him to the station, where his parole is revoked. Paul reveals he planted the drugs, but Nick is kept in prison after he assaults a guard. Paul's actions push Amy away from him. Consequently, Paul pays a top barrister a few months later to represent Nick in court.

Courtney hosts a silent disco at The Waterhole, but it does not attract much attention. Paul saves the event by turning it into a tea dance for his cousin Hilary Robinson (Anne Scott-Pendlebury) and her friends. After dancing together, Courtney tells Paul that they should make their relationship real, but Paul is hesitant. He later suggests to Courtney that they elope. Tim accosts Courtney outside Lassiter's, where she tells him that she and Paul are married. She then tells Amy, Leo and their friends. However, it emerges that they did not go through with the ceremony. Courtney begins packing up her belongings to move out of the penthouse, but she remarks that she has nowhere to go. Paul tells Tim the truth and brings him back to the penthouse to speak with Courtney. Tim tells her that he cares for her and apologises for pushing her too hard. He asks her to return home and she agrees. Courtney gives Paul her resignation from Lassiter's and he tells her to keep the engagement and wedding rings.
