List of Neighbours characters introduced in 2013

Nell Rebecchi, played by Scarlett Anderson until 2022 and by Ayisha Salem-Towner from 2023, made her first screen appearance during the episode broadcast on 7 January 2013. She is the daughter of Sonya (Eve Morey) and Toadfish Rebecchi (Ryan Moloney). Anderson was just four weeks old when she made her debut as Nell. Morey revealed that she instantly fell in love with her and joked that she had trouble letting her go after filming. She said "I just want her there all the time! I come home all excited about how I've been able to work with the baby. She's called Scarlett in real life and she's such a beautiful baby. Having her around just lifts everyone's mood, so we're very lucky."

Morey believed that she "wore down the writers" to give Sonya and Toadie a baby. She commented "After everything they have been through, it just seems like the most natural thing for these characters." Morey's character was pregnant at the same time as Vanessa Villante (Alin Sumarwata), which allowed the two women to share their experiences. Both actresses were required to wear prosthetic bumps, which would be increased in size every few weeks. Morey stated that she became attached to hers and would constantly rub it. On-screen, Sonya opts to give birth at home, but experiences serious complications and has to undergo a caesarean section at the hospital. Toadie and Callum Jones (Morgan Baker) are left "to frantically wait for news" and when Karl Kennedy (Alan Fletcher) cannot confirm the health of the baby, Toadie assumes that his daughter has died. A ''Soap World'' reporter said "Toadie is in agony until Karl finally reports that little Nell is healthy and happy. The new father joins a recovering Sonya and Callum to celebrate the newest addition to the family". Anderson's final appearance as Nell was on 28 July 2022 during the serial's finale.

Ayisha Salem-Towner took over the role of Nell when ''Neighbours'' returned in 2023, with the series' narrative moving forward two years from the finale. Moloney teased Nell's increased role in storylines with Salem-Towner in the role, describing her as "pretty phenomenal". He also noted that, unlike Salem-Towner, Anderson's casting from birth meant that she had not chosen to be an actor and could now enjoy her childhood. Upon the character's return, Nell is aged up.

When Sonya and Toadie decide to have a baby, they initially struggle to conceive and Toadie learns he has a low sperm count. The couple think about putting their plans on hold. When Sonya goes to the hospital to give blood, Rhys Lawson (Ben Barber) asks her to take a pregnancy test. Believing the test is negative, Sonya throws it away, but Rhys retrieves it and reveals that the test is positive. Following the first ultrasound scan, Sonya and Toadie argue about whose surname the baby will take and ultimately choose Rebecchi. After learning that they are having a girl, Sonya finds a photo of Nell Mangel and decides to give the name to her daughter. Sonya chooses to have a home birth and goes into labour two weeks early. When a complication arises, she is taken to the hospital and gives birth to Nell via caesarean section. Nell stays in the hospital for a couple of days with Sonya, before she goes home with her family. Sonya and Toadie later throw Nell a naming day ceremony, where she gets to meet her grandmother Angie (Lesley Baker). During his campaign to intimidate Sonya, Robbo Slade (Aaron Jakubenko) moves Nell's pram when she is looking away. Sheila Canning (Colette Mann) brings Nell back to Sonya, explaining that her pram was around the corner.

When Toadie and Sonya realise that Nell has become too reliant on technology to keep her entertained, they go through a 24-hour digital detox. A few weeks later, Nell suffers a fall at the local park when Sonya is briefly distracted. A DHS worker investigates the incident when a formal complaint is made against Sonya. The following year, Nell is stung by a bee and rushed to hospital, as she suffers a mild reaction to the sting. Georgia Brooks (Saskia Hampele) becomes distracted and almost gives Nell an overdose of paracetamol, but Sonya stops her in time. Nell begins biting people and Sonya and Toadie struggle to work out the cause of the issue. While babysitting Nell, Amber Turner (Jenna Rosenow) discovers that she is being influenced by a phone app. When Toadie is left paralysed after an accident, Nell becomes afraid of his wheelchair. Amy Williams (Zoe Cramond) helps out by dressing Toadie up as a spaceman and his wheelchair as a rocket to turn it into a game, which relaxes Nell. Sonya leaves Nell with Toadie, while she goes shopping, but he is unable to chase after Nell when she runs out the front door and into the driveway. Tyler Brennan (Travis Burns) stops Sonya from hitting Nell with her car. Sonya and Toadie separate, with Nell living at Sonya's, but having regular contact with her father. She grows close to family friend Mark Brennan (Scott McGregor), much to Toadie's jealousy. Nell swallows some medication she finds at the Kennedy household, resulting in an opiate overdose. She is rushed to the hospital, where she is stabilised.

Sonya and Toadie separate, and he moves out. Nell's kindergarten teacher tells Toadie and Sonya that Nell has been misbehaving, and she suggests that Nell be held back from starting school, leading Toadie to contact a child psychologist. Toadie eventually moves back into the family home after reconciling with Sonya. Nell meets her younger brother Hugo Somers (John Turner), born from a one-night stand between Toadie and Andrea Somers (Madeleine West). The following year, Sonya is diagnosed with stage four ovarian cancer and she decides not to tell Nell, who is starting school. Sonya's health rapidly declines and she dies, leaving Toadie as a single parent to Nell and Hugo. When Nell discovers that her uncle and aunt, Shane (Nicholas Coghlan) and Dipi Rebecchi (Sharon Johal), are moving to Sydney, she tells Dipi that she doesn’t want her to leave her like Sonya did. After talking to Toadie and Dipi by Sonya’s mural, Nell eventually accepts the fact that Shane and Dipi are leaving and accompany others in sending them off.

Later, Nell begins to get confused when she sees Amy Greenwood (Jacinta Stapleton) dating both Ned Willis (Ben Hall) and Levi Canning (Richie Morris) at the same time. After asking Toadie a lot of questions, she draws a picture of Amy holding hands with both Ned and Levi, which causes Toadie to confront Amy. Nell, Hugo, Toadie and Rose Walker (Lucy Durack) later go on a Father's Day picnic. After seeing Toadie's ex-girlfriend, Melanie Pearson (Lucinda Cowden), Nell asks if Melanie can play with her and go to the zoo. Rose says that she can take Nell to the zoo, but Nell says Melanie is more fun. Melanie later takes Nell and Hugo give Father's Day presents to Toadie, causing Toadie and Melanie to reunite. Nell asks Melanie to speak with her mother through her crystal ball, and Melanie tells Nell that Sonya likes her dress. Nell becomes obsessed with the notion that her mother can talk to her through the crystal ball. She is upset when Toadie accidentally breaks it and refuses to believe him when he says it is fake. Toadie and Melanie talk to Nell about keeping Sonya's memory alive by talking to her and she admits that she knew the crystal ball was not real, she just liked pretending. The following month, Nell is given an alcoholic jelly shot that was spiked by Zara Selwyn (Freya Van Dyke), but Karl tells Toadie that she will be fine. Nell goes to Toadie and Melanie's wedding a few months later and goes to their reception on Ramsay Street, where she plays cricket with her siblings and befriends Annie Robinson-Pappas (Harlow Ireland).

Following Toadie's wedding to Terese Willis (Rebekah Elmaloglou), Nell tells Hugo that she is opposed to their marriage and believes that Toadie is better suited to Melanie. Nell begins planting reminders of Melanie and Terese's ex-husband, Paul Robinson (Stefan Dennis), around the house. When she is out, Hugo snoops in her bag and picks up one of Melanie's china pigs. When Terese catches him, she confronts Nell, who says that her and Toadie are in denial about still loving Melanie and Paul. After hearing that Melanie's close friend Sharon Davies (Jessica Muschamp) is in town, she meets up with her, who gives Nell Melanie's address. When she goes to Melanie's house, she goes through the door and is knocked out by Eden Shaw (Costa D'Angelo), who had broken into her home. Melanie later finds her and returns her to Ramsay Street.
