His storylines included training to be an Olympic swimmer and being involved in two car crashes, with the second killing Jean Richards (Margot Knight), leaving Shane facing manslaughter charges. Writers also created a relationship story with Daphne Lawrence (Elaine Smith). O'Brien decided to leave Neighbours in 1986 and Shane departed during the episode broadcast on 3 March 1987. O'Brien reprised the role in July 2022 for what was then thought to be the show's final episodes. Shane returned on 12 November 2024, bringing his son Max Ramsay (Ben Jackson) to Erinsborough, before 26 November 2024 when he departed again, returning a few months later for the show's 40th anniversary in March 2025.

Casting Peter O'Brien auditioned for the role of Shane Ramsay twice in 1984 and following the cancellation of medical series Starting Out, he was cast as the older Ramsay brother.Oram 1988, p.96. O'Brien made his debut in Neighbours' first episode. Shane was one of Reg Watson's original Neighbours characters. The role of Shane made O'Brien a household name in his home country of Australia and overseas. Stefan Dennis originally auditioned for the role of Shane, but he was later cast as Paul Robinson instead. In the video The Official Neighbours Special: The First Ten Years, released in 1995, O'Brien said that he was working in England at the time when he received the role of Shane and he was not expecting Neighbours to last more than two years.

Development Shane was described by Network Ten as a "very together guy, despite being deprived of a normal childhood because of his father's obsession with his diving training". They also added that Shane had independence and an "inner strength". O'Brien described the character of Shane as "a bit of a misfit". In their 1989 book, The Neighbours Factfile, Neil Wallis and Dave Hogan wrote that Shane's father Max Ramsay (Francis Bell), had an obsession with him becoming a champion diver and that made Shane's childhood difficult.Wallis; Hogan 1989, p.64. He gained an "independent spirit" and became "easygoing" and a "genuine nice guy". Shane has a keen interest in motorbikes and this often leads him into trouble. He is a "strong silent" type of character but he still managed to "break the hearts of most of the available women who strolled down Ramsay Street." Mary Riddell of the Daily Mirror observed "Like any self-respecting male sex symbol, Shane has designer muscles and a beach boy suntan – coupled, in his case, with the brightness of a 40 watt light bulb." O'Brien told her that he chose to play Shane "a bit dumber" than he was meant to be and more quick-tempered, as he did not want the character to be so nice. He felt that Shane was wimpy.

Shane was paired with Daphne Lawrence (Elaine Smith) for a romance story. During the show's first-season finale, Daphne ends the relationship as she is in love with Des Clarke (Paul Keane). After breaking up with Des, Daphne reconciles with Shane and they become engaged, however, Daphne worries that she is rushing into marriage on the rebound and they end the engagement. A love triangle was then established between Daphne, Shane and Des. In June 1986, Stephen Cook from TV Week reported that Daphne would accept a marriage proposal from one of the men, which would result in marriage. Smith thought Daphne was best suited to Shane and said she had a great deal of love for him. O'Brien told Cook that as far as Shane is concerned, Daphne is the only woman he has ever loved and feels that he is more suited to her than Des. Whilst drunk at Paul and Terry Inglis' (Maxine Klibingaitis) wedding reception, Shane boasts about how badly he treats Daphne.Wallis; Hogan 1989, p.79.

Writers later devised a dramatic story for Shane, which sees him involved in a car crash which kills Jean Richards (Margot Knight). Shane is driving home from Daphne and Des Clarke's (Paul Keane) wedding when he loses control of his car and crashes into a stationary vehicle. O'Brien told Patrice Fidgeon from TV Week that "there's a blowout just as Shane is trying to negotiate a difficult turn coming down the hill. He loses control of his car and careers into a parked car." Jean dies and Shane feels guilty because he had drunk alcohol at the party. Though Shane had only drunk a small amount of alcohol. Alex Carter (Kevin Summers), a local resident gives him some brandy to calm his nerves following the crash. O'Brien revealed that Shane faces manslaughter charges as a result. The police arrive and breathalyse Shane, who is arrested and later released on bail. O'Brien explained that "if he loses his license Shane feels that's the end of his livelihood. But what shatters him the most is that he has killed a person."

In July 1986, O'Brien spoke publicly about his intention to leave the show. He stated that he had always planned to assess his future with the show after eighteen months. He originally planned to leave in September 1986, but added a three-month extension onto his commitments to the show. O'Brien did leave Neighbours later that year. The Grundy Organisation tried to convince O'Brien to stay, fearing that the show would suffer from his departure, but O'Brien was determined to move on. He later said that his departure was nothing to do with being typecast, but rather the amount of exposure. He explained "I've had enough of my shirts being ripped off my back. I've had to sneak out of places through the back door. If I go shopping or to the pictures, I get mobbed."

On 3 March 2022, it was announced O'Brien had agreed to reprise the role for the serial's final episodes. Shane returns during the episode broadcast on 13 July in the UK and 20 July 2022 in Australia. Joe Julians of Digital Spy reported that Shane returns to Erinsborough after becoming nostalgic. He also wants to "put some Ramsay roots back into the community again." Paul comes across Shane making noise with other guests outside Lassiters and they are "thrilled" to see each other again, before Shane reveals he has become a millionaire and wants to invest in Paul's business as joint partners. However, as Shane slowly learns about Paul's actions during the past few years, he is forced to rethink his deal.

In October 2024, it was announced on the Neighbours official Instagram account that Shane would be returning to Neighbours for a "visit" alongside his son and new character Max Ramsay (Ben Jackson). In January 2025, it was announced that Shane would return again for the show's 40th anniversary in March 2025.
