Neighbours 40th Anniversary is a group of four episodes of the Australian television soap opera Neighbours, broadcast on Network 10 each day from 17 to 20 March 2025. The episodes were directed by Harry Lloyd and Eugenie Muggleton. Executive producer Jason Herbison wrote the first two episodes, with Sarah Mayberry and Shane Isheev writing the remaining two. The opening titles were replaced with a special title card celebrating 40 years of the show.

Plans for the anniversary began once the show was picked up by Amazon in 2022. Herbison wanted to do something fresh for the 40th and focus on the future, compared to the nostalgic tone of previous anniversaries. Herbison and the production team settled on a celebration of "soapie twists and turns" with contemporary storylines that also honoured the serial's past. The episodes were planned to include elements that viewers loved about Neighbours, including big plots, new regular cast members, and appearances from returning characters. The anniversary uses Nell Rebecchi's (Ayisha Salem-Towner) "Story of Erinsborough" exhibition as a plot device to link past and present storylines. Herbison also wanted the episodes to be a catalyst for future plots that would continue over the coming months. To promote the anniversary, a theatre show titled Neighbours – The 40th Anniversary Tour was staged in the UK during February 2025. Herbison began promotion of the episodes in January 2025 and cast members were interviewed on television shows and by media outlets.

The anniversary begins with the wedding of Krista Sinclair (Majella Davis) and Leo Tanaka (Tim Kano), and the return of Chelsea Murphy (Viva Bianca) with her newborn son Thomas Murphy (Charlie Lyon), which causes big ramifications for Paul Robinson (Stefan Dennis). A fire at the local garage endangers the lives of five characters with Byron Stone (Xavier Molyneux) having to make an impossible choice, while the week ends with the mysterious death of Sebastian Metcalfe (Rarmian Newton). The anniversary received a mostly positive reaction from critics, with several of them including the episodes in their "Pick of the Day" features. Many critics enjoyed the "nods to the past", Chelsea's return and the revelation about Thomas' paternity, Charleston's arrival as Agnes, and Darcy's return. However, Neighbours' recent cancellation meant the anniversary was also described as "bittersweet" and "overshadowed".

Plot Episode 9208 (17 March 2025) Nell Rebecchi (Ayisha Salem-Towner) attends the opening of an exhibition of her manga project in the Lassiters complex, which celebrates the history of Erinsborough. JJ Varga-Murphy (Riley Bryant) meets Agnes Adair (Anne Charleston) and notices her resemblance to Harold Bishop's (Ian Smith) deceased wife Madge Bishop. Krista Sinclair (Majella Davis) and Leo Tanaka (Tim Kano) prepare to marry, with Leo unaware that Krista had sex with Sebastian Metcalfe (Rarmian Newton) the night before. Krista's sister, Fallon Morell (Kate Connick), tells her that she lied about having sex with Leo, and the wedding proceeds without Krista confessing her infidelity. Seb appears at the wedding venue, but Fallon and Taye Obasi (Lakota Johnson) prevent him from intervening. Remi Varga-Murphy (Naomi Rukavina) locates her sister-in-law, Chelsea Murphy (Viva Bianca), aware that she has recently had a baby whose father may be Paul Robinson (Stefan Dennis). She brings Chelsea and her son, Thomas (Charlie Lyon), to Ramsay Street, shocking Paul and Terese Willis (Rebekah Elmaloglou).

Episode 9209 (18 March 2025) Chelsea explains that either Paul or Jeffrey Swan (Tim Potter) is Thomas' father. They both agree to take a DNA test. Remi and Cara Varga-Murphy (Sara West) invite Chelsea to move in with them. Agnes visits the Eirini Rising retirement complex and meets Harold, who is shocked by her resemblance to Madge. They both conclude that it is best if she does not move in. Meanwhile, Max Ramsay (Ben Jackson) continues to hide out from criminal Carter, aided by his father Shane Ramsay (Peter O'Brien), Andrew Rodwell (Lloyd Will), Roxy Canning (Zima Anderson) and Holly Hoyland (Lucinda Armstrong Hall). Roxy is romantically pursued by Lachie Jensen (Jack Hayes) who, unbeknownst to her, has used her to locate Max. Byron Stone (Xavier Molyneux), his sister Nicolette Stone (Hannah Monson), and his girlfriend Sadie Rodwell (Emerald Chan) discover Max at Fitzgerald Motors with Roxy. Lachie throws a Molotov cocktail into the garage, setting it alight.

Episode 9210 (19 March 2025) Roxy, Max and Byron escape the fire but Nicolette and Sadie become trapped. Bryon uses a fire blanket to re-enter the garage and saves Nicolette, leaving Sadie behind. A flaming beam falls onto Sadie, causing burns to her back. In hospital, Sadie refuses to see Byron, feeling betrayed by his actions. Lachie gives up Carter upon his arrest, and Max is relieved that his ordeal is over. Terese and Nell move in with Paul, who promises to not allow Chelsea to come between them if he is revealed to be Thomas' father. The test results reveal that Paul is the father.

Episode 9211 (20 March 2025) Susan Kennedy (Jackie Woodburne) and Karl Kennedy (Alan Fletcher) are shocked when Susan's nephew, Darcy Tyler (Mark Raffety), is revealed as the tenant of Terese's house. Darcy assures them he has returned to Erinsborough to face his criminal past and make amends. Chelsea takes Thomas to Paul's penthouse, to Terese's discomfort. Krista tells Leo that she had sex with Sebastian and he returns to Erinsborough alone. Taye and Fallon see Sebastian in The Waterhole and attempt to convince him to leave Erinsborough. Later, Leo angrily confronts Sebastian, who taunts him about Krista. The following day, Sebastian's dead body is seen floating in Lassiters Lake.

Production Conception Neighbours executive producer Jason Herbison began plans for the anniversary once the show was picked up by Amazon in 2022. He wanted to do something "fresh and interesting" with the 40th, compared to the nostalgic tone of the 30th and 35th anniversaries and 2022 finale, which featured many returning characters and large events. Herbison wanted to focus on the future, rather than a large number of returning characters, although he planned for "an element of that". He told Johnathon Hughes of the Radio Times that "there are elements of nostalgia but it's more about looking forward than looking back. We always want to honour the heritage of the show, but recognise we need to keep evolving." Herbison and the production team settled on a celebration of "big soapie twists and turns" with storylines that were contemporary, but also acknowledged the serial's past, aiming to "own the genre" of soap opera. Herbison told Hughes that the episodes would feature "everything our viewers love about Neighbours", including "big stories" and returning characters. He and the team wanted to highlight "the nature of classic, serial storytelling", so they used Nell Rebecchi's (Ayisha Salem-Towner) "Story of Erinsborough" exhibition as a plot device to link both the past and present. Herbison planned for the episodes to be a catalyst for the show's future plots. He additionally told Inside Soap's Laura-Jayne Tyler that "the 40th anniversary week sets in motion stories that will continue for months to come."

Cast

Ahead of the anniversary, it was reported that several former cast members would be returning to the soap. In January 2025, it was announced that Mark Raffety would be returning as Darcy Tyler. Raffety's return had originally been planned to occur before Neighbours was cancelled in 2022. Later that month, it was announced that Zima Anderson and Peter O'Brien would be returning as Roxy Willis and Shane Ramsay respectively. Rebekah Elmaloglou, who portrays Roxy's aunt Terese Willis, teased that Roxy would do some "naughty" things that would disappoint Terese, with the actress calling Anderson and Roxy a "breath of fresh air to have around". Returning cast member Viva Bianca also returns as Chelsea Murphy, following brief appearances in late 2024 and early 2025. Her return also features the introduction of her newborn baby Thomas Murphy (Charlie Lyon), whose paternity causes issues for other characters.

Another former cast member to return during the anniversary was Anne Charleston, who portrayed Madge Bishop on-off from 1986 until the character's death in 2001, with subsequent appearances as visions. Charleston's return to the soap had been announced in December 2024, as part of Smith's permanent departure from Neighbours following his terminal cancer diagnosis, with Neighbours teasing at the time, "in what context Anne will appear is yet to be revealed, but to have the iconic couple reunited will be one final treat for fans". Herbison explained that Charleston's appearance was a nod to previous actors who had returned as new characters. He also acknowledged that Smith's cancer diagnosis had changed plans for his and Charleston's characters, due to uncertainty around how long Smith would be able to continue filming. Long-term cast members Jackie Woodburne and Alan Fletcher, who play Susan Kennedy and Karl Kennedy respectively, also returned to the show following a filming break, while Candice Leask returned as Wendy Rodwell following an extended on-screen absence.

Storyline development Michael Darling from Whattowatch.com interviewed Elmaloglou, Majella Davis (Krista Sinclair) and Tim Kano (Leo Tanaka) about the anniversary's storylines. Elmaloglou described "incredible" stories, adding "it's just bombshell after bombshell really." Davis said "there are lots of bombs being dropped on these poor characters and lots of reminiscing of the 40 years that Neighbours has been around." Kano concluded that the plots have numerous "omg moments" and "there's so much going on and fans are going to be really satisfied with all the nods to the past." Kano believed that the writers had created storylines to satisfy the show's entire fanbase, which pay homage to the past for long-term viewers and to the present for new viewers.

One of the anniversary's main storylines revolves around the wedding of Leo and Krista. Davis and Kano had an hour-long meeting with Herbison in 2024, where he discussed their upcoming storylines and revealed his plans for their role in the 40th anniversary. Herbison informed them that their wedding storyline would be jeopardised by infidelity and Davis assumed it would be Leo who cheats on Krista. However, Davis was shocked to learn it would be Krista who has sex with Sebastian Metcalfe (Rarmian Newton). Her betrayal occurs after being manipulated by her sister, Fallon Morell (Kate Connick) and Sebastian into believing that Leo has had sex with Fallon. Davis revealed that this made Krista's actions, which she described as "reckless", more justifiable. She explained that Krista wants to feel desired during her turmoil, adding "it was justifiable in my head, but also pretty heartbreaking." Kano added, "It didn't really settle in until we walked out of the meeting. We were heading back to the green room like: 'Hang on, what? What's going on?'" Kano also told Darling that the scenario is the characters' "worst nightmare, it's huge." Kano likened the build up to the wedding episode to a roller-coaster. He believed that there are "lots of mixed messages" and "a lot of people meddling with their relationship and trying to derail it." Fallon and Sebastian divulge all their secrets to Krista during the first anniversary episode. Davis noted that once Krista realises Fallon lied, "it's like the world is spinning around her." Their admission that they used to be in a relationship adds additional shock and Davis likened this narrative to a series of exploding bombs. Davis concluded that Krista's realisation of Leo being innocent is "just awful".
