Mackenzie Hargreaves is a fictional character from the Australian soap opera Neighbours, played by Georgie Stone. She made her first appearance on 30 August 2019. Mackenzie is the soap's first transgender character, added to the series after Stone wrote to executive producer Jason Herbison to pitch the character. She arrives as a new student at Erinsborough High School and is connected to the established Rebecchi family, who she knew prior to her gender transition. Following her initial guest storyline, Mackenzie was a central character in spin-off series Neighbours: Erinsborough High before being promoted to the regular cast of Neighbours in 2020. She remained with the series until its finale episode, broadcast on 28 July 2022, and reprised the role when the series resumed on 18 September 2023. Her exit aired on 17 September 2024. Stone reprised the role again in 2025 for the show's final episode.
Following an initial focus on her transgender identity, Mackenzie's later storylines aimed to treat the character similarly to other female soap characters. The character is portrayed as ambitious and desiring "fairy tale" experiences where she is fully treated as a woman. Her relationship with Hendrix Greyson (Ben Turland) leads to marriage after he is diagnosed with a life-threatening condition; he dies shortly after the wedding, leaving Mackenzie a widow. Subsequently, she enters into a relationship with Haz Devkar (Shiv Palekar). The character and the soap's use of transgender storylines were positively received, though Mackenzie's "self-righteous" stage and her lack of a happy ending following Hendrix's death received some criticism.
Creation and casting
Stone approached the show about introducing a transgender character in 2018. She wrote a letter to executive producer Jason Herbison with some ideas and received a response two hours later. Following an audition, Stone was cast as Mackenzie and she worked with the producers for eight months to ensure that parts of her own story would be included in the character's storyline. Mackenzie is the show's first transgender character, and the second trans actress to portray a trans character on Australian television. Stone's casting was announced on 23 March 2019. Stone stated "I am so excited to be joining such an iconic show. Neighbours is all about telling stories we can connect to, stories that reflect our society today. It has progressed so much since it first began, which is why I thought it was time to have a trans character on the show. I can't wait for everyone to meet her!" Herbison added that during her audition, he became aware that Stone "would be able to tell the story truthfully and authentically".
Stone began filming her scenes in June 2019, with her initial storyline running for two months. Mackenzie is connected to established character Shane Rebecchi's (Nicholas Coghlan) past, and attends Erinsborough High School. Stone worked with the Neighbours writers to ensure Mackenzie's transgender identity was portrayed authentically. Stone was complimentary of the experience, stating that "I was surprised at how switched on the writers were, at how eager they were to get this right. They were really good listeners." Stone explained to a columnist for The Australian Women's Weekly that she knew her character's story would have to have drama, but she helped to "ensure it's truthful at the same time" by including various experiences that trans people go through, including coming out, relationships, and shame due to bullying. Stone also wished for Mackenzie to be "just be a regular teen at the same time, and get caught up with the teen drama which has nothing to do with her being trans."
In a guest editorial for Metro, Stone outlined her motivation for pitching the character and the choices made to bring her to the screen, stating that "when we can see ourselves reflected in the characters on our screens, it allows us to feel seen and acknowledged". Stone claimed that "I wanted to tell an overall positive story for all the young people who watch the show, while not shying away from some of the difficult experiences trans people face (these stories need to be told). I wanted the message to be, ‘you will be OK, you are loved’, not ‘you are the problem, this is your fault and you will probably die alone’." She described the aim of the character as "educational and hopefully beneficial for the trans community but, at the end of the day, remain[ing] an exciting and compelling story that fits in with the wider world of Neighbours." Ultimately, Mackenzie avoids being a "token trans character" and "isn’t used as a tool in other characters’ stories, but is given her own arch where she can grow and evolve, and bring other people along with her." Stone affirmed that Mackenzie is "absolutely the character I wish I had seen as a kid."
Development Characterisation, introduction and initial storyline
Shortly before her introduction, Stone gave more details on Mackenzie's fictional background, explaining that her father rejected her from a young age and her mother, who was supportive, died a few years ago. Mackenzie has had a rough time and is not very trusting of people as a result. Stone added that her character is "a bit world weary, a bit cynical, a bit hardened by her experiences." Stone stated that Mackenzie "is a fully realised human; her desire for love and safety, and her fear of rejection and isolation generate a very interesting dichotomy." Her backstory and characteristics were designed with the intention of separating the character of Mackenzie from Stone's own personality. Stone subsequently described Mackenzie as "an alternative reality version of myself". She explained that "Mackenzie carried more shame and anxiety with her and she’s definitely less confident in herself [than me], and less trusting of other people, and I wanted her to come across as someone who’s really really unsure of who she is, not in terms of her gender identity but in terms of who she wants to be as a person". Describing Mackenzie's journey, Stone described how "sometimes when you’ve been bullied for a long amount of time like Mackenzie, or she’s had years of trauma, it’s not something that you can shake very easily... It’s not a black and white journey from A to B of going from ashamed to not anymore, it’s kind of a cycle or bumpy road where it’ll all come back".
Mackenzie's initial storyline saw her arrive as a new student at Erinsborough High and befriend Yashvi Rebecchi (Olivia Junkeer). Yashvi recognises Mackenzie and wonders if they knew each other in her home town of Bourke, before noticing Mackenzie's interest in her father, Shane Rebecchi (Nicholas Coghlan). This leads Yashvi to suspect that her father had an affair and Mackenzie is his secret daughter, forcing Mackenzie to reveal that she knew the family prior to her gender transition. While Yashvi is portrayed as supportive of Mackenzie, the story explored transphobia when she made an unguarded comment that Mackenzie "used to be a boy", both revealing her limited understanding and outing Mackenzie to the student body. Subsequently, Mackenzie is bullied and threatened not to use the school's girls' toilets and principal Susan Kennedy (Jackie Woodburne) asks her to use the disabled bathroom until the situation is resolved. Yashvi and Shane are upset by this, with the former staging a peaceful protest by encouraging all other students to use the disabled toilets in a display of solidarity.
Mackenzie is also searching for her estranged father, Grant Hargreaves (Paul Mercurio), who failed to make contact after her mother died, upon her arrival in Erinsborough, and enlists Shane's help to find him. As the storyline continues it emerges that, in addition to Grant's rejection of her transgender identity, Shane shared his ignorance and encouraged Grant to burn her belongings. Shane's guilt leads him to confess to Mackenzie, who struggles to forgive his past actions. Shane eventually locates Grant and asks him to come to Erinsborough, but Mackenzie is disappointed to discover his attitudes have not significantly changed. The storyline culminates when Grant fails to attend the father-daughter dance at Mackenzie's school formal, with Shane electing to dance with her in his place.
Shortly after her introduction, Mackenzie shares a flirtation with Hendrix Greyson (Ben Turland) when they both attend a party, after which she wonders whether to tell him she is transgender. She briefly leaves the party to seek advice, and when she returns she "tentatively" comes out to Hendrix, whereupon he calls her "the hottest girl at the party" and kisses her. Although Hendrix and Mackenzie attend the school formal together, they spend little time together and she witnesses him kissing Olivia Lane (Grace O'Sullivan).
Moving to Ramsay Street and family relationships On 19 October 2019, it was announced that Stone would be promoted to the regular cast in early 2020, following a positive response to the character, the storyline, and Stone's performance. Stone expressed her delight at the news and looked forward to exploring Mackenize further. Herbison planned to develop the character so that "transgender doesn't even warrant the batting of an eyelid", something he deemed to be a "powerful" movement. Mackenzie returned to the series from 4 February 2020.
A short time later, Mackenzie's aunt, Trish Symington (Katherine Tonkin), announces she is moving to Fremantle, prompting Mackenzie to look for an alternative place to live. Feeling unable to ask Shane and Dipi Rebecchi (Sharon Johal) following the death of their friend Gary Canning (Damien Richardson), Mackenzie schemes with Roxy Willis (Zima Anderson) to trick Trish into leaving her alone in her flat. After struggling with living alone, Mackenzie invites Mannix Foster (Sam Webb) to rent her spare room, unaware of his criminal nature, leading to a police raid on the flat. Following this, the truth of Mackenzie's living situation comes out and the Rebecchi family invite her to stay with them.
Grant was subsequently reintroduced amidst episodes themed around LGBT pride. Grant returns to Erinsborough claiming to want to spend time with Mackenzie, though he actually intended to ask Toadie Rebecchi (Ryan Moloney) for legal advice after suffering an injury. Grant attends a Lassiters Pride event with some discomfort, but publicly describes Mackenzie as his daughter after winning a bingo game. Later, Mackenzie learns of the motivation for Grant's visit on the day she is due to read from her diaries as part of a Writers' Festival. The shock of the revelation causes Mackenzie to pull out of the event, but Grant reads some entries on her behalf. Stone wrote the diary entries read aloud by Grant and Dipi, and was credited as a co-writer of the episode. She stated that she was "really thrilled to be asked to write [the entries] because Jason wanted them to be as authentic as possible". Stone also "chose the years for each event and personal moment for Mackenzie". The scenes culminated in a breakthrough for Mackenzie and Grant's relationship, as she witnessed his reading of her diary and he then apologised for his past treatment of her. Commenting on the future for the characters, Stone stated that "It is a process. He hasn’t become a completely different person, but I think what has changed is that he is trying to be the best father he can possibly be and Mackenzie can see that – and she appreciates his efforts".
