Characterisation She is described on the show's official website as being "a cautious kid and a thinker". She likes to play it safe and dislikes gossiping. Despite Maddy being a talented violinist, Clementi can not play the instrument but has taken violin lessons.
Introduction In a November 2012 interview, producer Lucy Addario said that
Home and Away would revisit the issue of fostering. The refocus allowed her to introduce "new talents" to the show. Maddy is a teen runaway, who arrives in the Bay with
Spencer Harrington (
Andrew Morley). Maddy falls ill and she and Spencer are found living in the local high school. They later turn up on the doorstep of
Roo Stewart (
Georgie Parker) and
Harvey Ryan's (
Marcus Graham) home. They leave Maddy and Spencer food and an offer of help. Clementi told a reporter from
Inside Soap that "at first, they're very reserved about Roo's offer - they know that living with others presents the possibility that whatever they're hiding may be revealed." The duo remain reluctant to accept help until Maddy becomes ill. But she later noted that it was the point that Maddy accepts help. Parker told Claire Crick from
All About Soap that Roo can empathise with Maddy and Spencer because of her own history. Roo is "immediately drawn to them" and angry that no one else views them the same way. Parker was pleased with fostering themed storylines because the show was about "giving people with nowhere to go a home". Parker also wants Roo to become their actual foster parent. Maddy decides that she is ready consummate her relationship with Spencer on his birthday. Morely told ''Inside Soap's'' reporter that "now they're more settled in the Bay and their relationship is stronger, they feel it is the right time."
Car accident Following her break-up with Spencer she begins to behave erratically. She befriends
Casey Braxton (
Lincoln Younes) who is upset over his ex-girlfriend
Tamara Kingsley (Kelly Paterniti). She decides to comfort him and tries to seduce him. Younes explained that his character rejects her advances because he senses that she will feel better in the future. He knows that she is doing it for the wrong reasons and chooses to do the "noble thing". Maddy later attends a party with Casey and meets
Josh Barrett (Jackson Gallagher). Roo attempts to convince Maddy to come home but she refuses. She sneaks off with Josh to avoid Casey taking her home. Younes told a
TV Week reporter that Casey knows Maddy is trying to lose her virginity and he believes it is not right.
Relationship with Josh Barrett Following the accident Maddy tries to support Josh. He decides to try to make amends with the Braxton family but they are not interested. She comforts him and they kiss. Gallagher told Gavin Scott (
TV Week) that it his "dream come true". He added that "Maddy is just this beautiful girl, he's blown away by her beauty. He has fallen in love with how sweet and caring she is." Their relationship later becomes scrutinised by fellow characters following a fire at Mangrove River High School. The police believe that Maddy and Josh have started the fire because they find CCTV footage placing them at the scene of the crime. Writers continued to use Maddy's involvement with Josh as ways to create dangerous scenarios for the character. One example occurred when Josh chooses to spend time with Maddy, leaving his brother Andy jealous. The latter spikes Maddy's drink and she begins to behave oddly. Josh discovers the truth and fight ensues over Maddy. Josh and Maddy's relationship comes to an end. He begins dating
Evelyn MacGuire (Philippa Northeast) but Maddy remains in love with Josh. Following Casey's death Josh is feeling vulnerable and Evelyn rebuffs his attempts at being intimate. Josh seeks comfort with Maddy and they sleep together.
Cancer The show created an issue led plot for Maddy which began airing in November 2014. Maddy is taken ill during the night with a "mystery illness". Doctor
Nate Cooper (
Kyle Pryor) assumes it is a virus but runs blood tests to find out. Maddy discover that she is pregnant and assumes that Josh is the father. But when
Marilyn Chambers (
Emily Symons) points out that she looks more than eight weeks pregnant she realises that Oscar might be the father. When Maddy goes to have a scan to determine the father Nate is shocked to discover that she is not pregnant. Nate informs her that she has a suspicious mass growing on one of her ovaries. Clementi said that it no-one saw the shock coming. The news is "life changing" for Maddy, and she had already endured too much drama during the suspected pregnancy. The actress was an ambassador for a cancer charity, so was keen to depict the "raw truth" of the illness. Her main priority for her was to do the storyline justice and make it accurate for real life cancer patients. Maddy learns that having chemotherapy may mean she will be infertile. Having already had one ovary removed, Nate tells her that her only hope is having tissue removed and stored. When Roo learns that Maddy has left she asks Oscar to help find her. He discovers her "bucket list" and realises where she is. Oscar travels to the city to find Maddy and convinces her to return home for treatment. Clementi later commented that she believed Maddy's time in the city helps her accept her diagnosis. She has the space she needs to think and realise her cancer may not be a "death sentence". Oscars influence helps her to be a "strong woman" and he continues to support her. The actress noted a "connection that is unspoken" and "unbreakable bond" between Maddy and Oscar, adding "he really gets through to her". Writer's decided to introduce a romantic side plot in which Maddy embraces her feelings for Oscar and they begin dating. But she begins to overexert herself which leads to her nose bleeding while on a date with Oscar. But Oscar soon realises that Maddy's illness is affecting his school work and he decides to break-up with her. In an additional story writers dealt the absence of Maddy's mother
Tanya Osborne (Kathryn Hartman).
Amputation and departure Maddy is one of several characters heavily involved in the show's caravan park explosion storyline. She suffers a life-threatening injury to her arm, which requires amputation. Maddy is "hysterical" upon learning that she will need to have her arm amputated in order to stop the spread of deadly toxins in her body. She initially refuses to sign the consent forms until Roo convinces her that the surgery will save her life. Stephen Downie of
TV Week noted that Maddy is left "broken and confused" by the ordeal. Georgie Parker commented: "I think Maddy feels that, having battled cancer and survived it, and having been through this horrific accident, she just wants to get out. She's a young women now. She's left school and wants the freedom to experience the world." She filmed her final scenes in late 2015. In a post on her social media, Clementi stated "And that's a goodbye to Maddy Osborne! From 2012 - 2016 and through several runaways, teenage pregnancy, ovarian cancer, meningitis, a few explosions, the loss of a limb, lots of tears and more boyfriends than I can count... Thank you for watching Maddy grow up (and me simultaneously) on the sands of Summer Bay and for all the love and support for one little teenage runaway xxx." ==Reception==
