She soon has her eye on John Palmer (Shane Withington) and approaches him while he is dining alone at Salt; the pair initially hit it off and Susie takes keen interest in John's personal life. The two eventually become more involved with one another and when Susie claims she has no place to live, John agrees to let her move in. Susie shows signs of suspicious behaviour when she begins asking questions and searching through John's bank statements, aside from feeling uninterested every time John touches her. Susie then persuades John to run for Surf Club president, much to Alf Stewart's (Ray Meagher) shock as it is unusual for anyone to run against him for president. Marilyn Chambers (Emily Symons) confronts John about his sudden change of character since he has started seeing Susie, causing her to clash with Susie on a number of occasions. Fed up with Marilyn's interference, Susie presents Marilyn with divorce papers from John. Following John's appointment as president, Susie persuades him to raise money for the Surf Club's renovation and she attempts to get sponsorship from local businesses such as the diner and the gym.

Irene realises that the wine meant for her was drugged, which sparks her suspicions even further when Susie refuses to seek medical help for John. Justin and Leah receive the news that the house they believe was sold to them is not actually theirs. Irene and Willow Harris (Sarah Roberts) soon discover that Susie McAllister does not exist when they stumble across a photo of Susie with the name Imogen Simons attached. Susie tries to convince everyone that Irene is spreading lies about her and advises Justin and Leah that there was an administrative error with the house which she intends to rectify. All becomes clear when Susie decides it is time to flee with Justin and Leah's life savings, along with the Surf Club funds. Irene confronts her and Susie drugs her with chloroform. Susie finally makes her escape, leaving John heartbroken, while Justin and Leah realise that they have lost all $90,000 of their money, as there is no trace of anyone by the name of Susie McAllister.

Several weeks pass and Leah is still determined to find Susie, while trying to convince John to help her. She eventually comes into contact with another of Susie's victims, Stephen Tennyson (Bren Foster), via an online forum, who claims that he and Susie had a brief relationship before she ran off with his life savings. Leah, John and Stephen continue their search to no avail, until John receives text messages from Susie. They plan a meeting that proves unsuccessful when she does not appear. Susie's body is recovered from the ocean and it is determined that she was killed by blunt force trauma to the skull, not drowning. The police realise that Susie could not have sent the texts to John, as she was already dead. Justin becomes the prime suspect after Susie's phone is found in his car. Leah later realises Stephen is the culprit, after finding a burner phone, Susie's laptop, and her and Justin's money in his motel room. Stephen tries to escape Summer Bay with Leah in fear that she will turn him in, but is eventually arrested and charged with Susie's murder.

Sienna contacts Nikau Parata after seeing an award-winning photograph of him and arranges a meeting. Nikau's uncle Ari Parata (Rob Kipa-Williams) also joins them and asks Sienna what she wants with his nephew. She offers Nikau a modelling contact, which he initially turns down, until she agrees to provide his girlfriend Bella Nixon (Courtney Miller) with an internship with a top photographer. Sienna is surprised when Nikau and Bella turn up together at SLM Management to create Nikau's portfolio. Sienna takes Nikau off to brief him on what to expect, and they join Bella and Emmett Ellison (Jaime Robbie Reyne) to take his first photographs. Nikau walks out on the session as he is uncomfortable, but soon returns and Emmett gets Bella to give him directions, which Sienna loves and she calls Nikau a natural. A few days later, Nikau is booked for a fashion campaign alongside Allegra Freeman (Laura McDonald), which is overseen by Sienna. She tells Nikau to attend a party thrown by the client and when Bella tries to get him out of it, Sienna tells her to re-read his contract.

Nikau threatens to quit, but Sienna manipulates him by blaming Allegra and then telling him that Bella would also lose her internship. Nikau decides to continue after seeing his first pay cheque. Sienna encourages Nikau to increase his online follower count with the help of Allegra by hosting a pool party at his house. She overhears a disagreement between him and Bella, and she and Allegra later mention how relationships with those not in the industry do not work out. Nikau tells Sienna that he is committed to Bella, which leads her to tell Bella that she cannot use any photographs of Nikau in her exhibition, unless she pays his daily fee. Emmett and Bella try to reason with Sienna, and Nikau threatens to withdraw from a major fashion shoot in Japan if she does not release the photos.

During another shoot, Sienna manipulates Allegra into creating a wedge between Nikau and Bella, after she learns that Nikau wants Bella to come to Japan with him. Nikau helps bring up a box of clothes to Sienna's apartment, and while he is waiting for a limo to take him to Bella's exhibition, Sienna tells him about her failed relationship with Emmett and tries to keep him from leaving. She tells Allegra to get something more, and when Allegra sends through photos of Emmett and Bella looking intimate, Sienna seduces Nikau and they have sex.

She later turns up in the Bay and Nikau confronts her about setting him up. Sienna spends the afternoon looking at Emmett and Bella's exhibition, while Nikau worries that she is going to tell Bella what happened between them.

Sienna responds by threatening to tell Bella what happened between them.

Sienna calls Nikau and Allegra for a last minute fashion shoot. Bella confronts Sienna and tells her that Nikau is not her pet. Sienna apologises and then offers Bella the chance to be the photographer for the shoot, after their photographer fell through. Bella accepts, but Nikau tells Sienna to leave her out of it.

Nikau's uncle Tane Parata (Ethan Browne) joins Sienna for a drink and she tries to seduce him, but he warns her not to mess with Nikau. Bella learns that Nikau cheated on her and she confronts Sienna, and has to be pulled away. Tane calls Sienna a player and tells her to leave town. Sienna gloats that she was always going to win and now Nikau is free to go to Japan. However, Nikau tells Sienna that he is done with modelling.

They have done an amazing job."^[24] Allegra was billed as a "sexy and scandalous model" who works with Nikau.^[23] She was also called "morally challenged" by Kerry Harvey of Stuff.^[25]

Allegra is being photographed by Emmett Ellison (Jaime Robbie Reyne) when he notices Bella Nixon watching on. He invites her to sit in the rest of the session.

Nikau also confronts Allegra about the texts and for messing up his life, while Allegra tells him that the Japan trip is her last chance to make it big. She refuses to take the blame for Nikau having sex with Sienna, and advises him to do what Sienna wants. Later at Salt, Allegra teases Sienna about wanting Bella to fail and torturing Nikau. Allegra tells her that getting him offside could jeopardise the Japan trip. Nikau later quits the agency, after the truth about him and Sienna comes out.

I had a tour lined up that was going to keep me busy for the year and I remember the week before lockdown happened going out and celebrating the tour.

I had just moved into a new house and was thinking, 'OK, so where do we go from here?'"^[25] Reyne's character is introduced as part of a big storyline set in the modelling industry and centred around Nikau Parata (Kawakawa Fox-Reo) and Bella Nixon (Courtney Miller).

Emmett assures Bella that she is talented and offers to collaborate on a photography exhibition with her. Emmett spends the night with Mackenzie again, but her brother Dean Thompson (Patrick O'Connor) warns him to stay away from her. Mackenzie leaves a number of voicemails on Emmett's phone, so he comes to Salt to tell her that their fling is over, causing her to chase him out of Salt.

Sienna tries to lure Emmett back to her agency, and away from the exhibition, with the promise of a big client and more money, but he rejects her offer. Emmett suggests that he and Bella hold a smaller exhibition in preparation for the one in the city. Mackenzie allows them to hold it at Salt and it is a success.

Kennedy was also pictured wearing a neck brace.^[28] Home and Away marks Kennedy's first soap opera role.^[29] Of her character's introduction, Kennedy stated: "Rachel lands in Home and Away in quite a different way.

Rachel bumps into Christian Green as she is leaving the Blue Bird Skydiving office. She admits that she is nervous ahead of her first solo skydive, which is a post-divorce present from her friends. Christian tells her that he has never done anything like skydiving before and is not sure he will get to jump today, but Rachel assures him that he will. Rachel is seriously injured after falling to the ground during her skydive. She is treated by Christian, who has just finished booking his own lesson when the call about Rachel comes through to the office. Christian recognises that Rachel is going into shock and attempts to calm her, before she is taken to Northern Districts Hospital. Rachel's x-rays show that her skull has separated from her spine and is only being held in place by ligaments. Christian informs Rachel that she has suffered a rare atlanto-occipital dislocation, but her spine is intact and he is organising a halo brace for her. Christian reassures Rachel that she is not going to die and he will get her through it. Rachel's condition steadily improves and Christian spends time with her to monitor her progress. Rachel learns that he has postponed his wedding to Tori Morgan (Penny McNamee) and she feels guilty that he chose her over his own wedding.

Christian tells Rachel that he almost died and it made him question everything. He believes that he survived in order to be at the skydiving site to save her. Christian decides to pass Rachel's care to another doctor, but she tells him that if he had ignored that feeling, she would not be alive. She tells him that she actually booked the skydive herself, so may be there was a reason she was there that day too. Rachel's condition steadily improves and she is able to walk around the hospital. Nurse Jasmine Delaney (Sam Frost) tells Rachel that the physio will be taking over her care soon. Tori later finds Christian asleep in Rachel's room when he is meant to be keeping an eye on her brother, and she confronts Rachel about their connection. A couple of weeks later, while they are talking, Christian tells Rachel that he and Tori are taking some time apart. He later calms her down when she suffers a panic attack and arranges some days out to the beach for her. Christian informs Rachel that she is ready to have the halo brace removed and for her to go home. She tells him that it is not necessary a good thing, as she will not see as much of him anymore and he realises that she has feelings for him. She points out that they have a connection, but he tells her that he loves Tori and only sees her as a friend, which she accepts. After Christian removes the brace, Rachel tells him she going to visit the beach one more time to say goodbye. As she is leaving, Rachel walks into the road and is hit by a car. She is brought to the hospital, where Christian takes over resuscitation, but she dies from her injuries.

Cash Newman, played by Nicholas Cartwright, made his first appearance on 14 June 2021.^[31] The character and Cartwright's casting were revealed during a promotional trailer released on 8 June.^[32] Home and Away marks Cartwright's first television role since his graduation from National Institute of Dramatic Art (NIDA).^[31] Cartwright had spent six years in the army, before he completed a three-year course at NIDA.^[33] The COVID-19 pandemic affected his search for acting work, and he applied to join both the New South Wales Police Force and the Australian Federal Police, while continuing auditions.^[33] Cartwright originally auditioned for the guest role of Lewis Hayes (later played by Luke Arnold), but he admitted that he was happy not to have won the part, as Cash was "a much better fit for him."^[33] Of joining Home and Away, Cartwright told Kerry Harvey of stuff.co.nz "The exposure the show gets is nothing like I've ever been used to before but, having said that, I'm really excited by it all and it's a real privilege to be here."^[33]

Cash is Summer Bay's new police constable. Cartwright felt that his military background, as well as his understanding of rank, helped him with the role.^[31] He was aware that the Bay was not the best place to be a police officer, after three previous constables were killed-off and Colby Thorne (Tim Franklin), the officer he replaced, serving a long prison sentence. Cartwright commented "There seems to be a curse, for sure."^[33] Cash's "welcome to town is pretty serious" when he has to arrest Justin Morgan (James Stewart), before leading an investigation into a body that washes up.^[31] Although billed as a "hot cop", Cartwright said there would be more to his character "than meets the eye."^[31] In an interview with Inside Soap's Sarah Ellis, Cartwright said there were skeletons in Cash's closet and he was not the "level-headed guy that he appears to be..."^[34] He also said playing a police constable was one of his favourite parts of the job, as he gets to portray all the family and relationship dramas that other characters have, but he also gets to jumps into a police car and chase down a criminal.^[34] Cash's sister Felicity Newman (Jacqui Purvis) is later introduced to the serial, and Cartwright told Ellis that he and Purvis had a "fantastic rapport".^[34] He said Felicity was the only person Cash could be himself around.^[34] Cash also forms a romantic relationship with Jasmine Delaney (Sam Frost).^[34] Cartwright thought the couple were "made for each other", and explained "It's just a really nice love story, which is quite rare in soap. They're going from strength to strength, and I'm really excited to see where the writers go with it next."^[34] He added that he had a good working relationship with Frost and that they were both looking forward to Cash and Jasmine's romance continuing.^[34]

Logan Bennett, played by Harley Bonner, made his first appearance on 10 August 2021.^[35][36] The character and Bonner's casting was announced on 25 March 2021.^[37] Of joining the serial, Bonner stated "It's been a while since I've had the privilege of working on a program that's such a hallmark of Australian television. I'm happy to say I picked it back up a lot faster than expected. I really love working on shows like Home and Away, I love my character and I can't wait for Australia to meet him."^[37] Bonner filmed some of his first scenes in the studio, before taking part in a week long shoot in Yass as part of the show's mid-season cliffhanger storyline, which introduces his character.^[36] Logan's introduction sees him attend the scene of a car accident, involving three of the show's established characters. Clips of Logan helping to load a patient onto a medical helicopter saw him mistaken for a paramedic, but Bonner explained that he is actually a trauma surgeon who has served overseas.^[36]

Logan ends up coming to Summer Bay to perform a life saving operation, before deciding to stay to "see his patient's journey through from start to finish".^[37] Bonner stated: "That's the main brunt of the character at this point. He's coming in and he's got some more uncouth ways of operating – figuratively and literally – than what Australia is used to and particularly what Summer Bay is used to. But he is effective and he's very confident in what he does. He's a real cheeky character and he's a lot of fun to play."^[36] Bonner also called his character "a bit of a nomad" and described him as "capable, compassionate, intelligent and fun."^[37] Bonner also expressed his interest in finding out more about his character during his time in the Bay.^[37] A few months later, it was confirmed that Logan would be a love interest for Mackenzie Booth (Emily Weir).^[35] On 8 January 2022, it was announced that Bonner had left Home and Away, as he had not been vaccinated against COVID-19 and Seven Network requires all staff working on their productions to be vaccinated.^[38] A show spokeswoman confirmed Bonner would not be returning to set when filming resumes on the serial and that the role of Logan will not be recast.^[38] The character's "abrupt" exit aired on 6 June 2022.

Felicity "Flick" Newman, played by Jacqui Purvis, made her first appearance on 19 August 2021.^[35][40] Purvis's casting was announced in April 2021, after she photographed filming alongside cast member Ethan Browne at Palm Beach.^[41] Dan Seddon of Digital Spy believed that she would become a potential love interest for Browne's character Tane Parata.^[41] Further details about Purvis's character, including her name, were released on 26 July, as she was featured in a promotional trailer for the show.^[35] Purvis originally auditioned for the role of Mackenzie Booth prior to being cast as Felicity. She told Kerry Harvey of Stuff that she was grateful she did not get cast as Mackenzie as she felt Flick was "a dream come true as a character."^[42] She continued: "I get to transition from vulnerable and sensitive with my family issues and mental health to the fun side, which is that she is a little pocket rocket who has no filter. So it's a huge, huge blessing and I'm just so grateful that I get to play it."^[42] Shortly before her first scenes aired, it was revealed that Felicity is the sister of Cash Newman (Nicholas Cartwright), Summer Bay's newest police officer.^[43]

Flick was initially billed as "a firecracker with an abundance of confidence and no filter – which can get her into a lot of trouble."^[35] Her first scenes see her attract Tane's attention when she dances on top of a bar.^[35] Purvis described her as "a kind of cannonball" and thought it was "a gift" to be given the chance to portray "a multi-layered character."^[42] Flick and Cash's fictional backstory was slowly revealed to viewers after their introductions. Their father committed suicide after when he was left to raise them alone and his farm suffered from drought. Flick struggled to come to terms with what happened, causing her to make one bad decision after another.^[42] Purvis felt privileged to play out the long lasting effects of suicide on the people left behind. She carried out her own research into the subject, wanting to portray it accurately and with sensitivity. She also spoke with people who had experienced a suicide in the family.^[42] She told Harvey: "It's different for everyone, obviously, so I just had to choose something specific for Flick and how she would react to that situation. I just needed to cover all bases and make sure that I was doing it justice and was covering it sensitively. It is very hard, but also so enlightening at the same time."^[42] Purvis reckoned Flick would always struggle with her father's death.^[42] She added that she understands her character, but Flick often does things she would not consider, like dancing on a bar.^[42] The show's 8000th episode, broadcast on 27 March 2023, featured Felicity's wedding to Tane.^[44]

The character and Evans' casting details were confirmed on 6 September.^[45] Evans had little acting experience prior to getting the role, but he said he was learning each day. He stated: "It is like getting paid to go to school. My first day in the studio, I kind of had a bit of a freak out because it's just a lot of people around and I didn't know what I was doing. I'm just trying to learn on the job."^[46] Prior to his arrival, it was revealed that Theo would have a connection to one of the show's main characters.^[45] It was later revealed that he is the nephew of established regular Leah Patterson (Ada Nicodemou).^[47]

The character was initially billed as "a troubled guy in his 20s", although Evans said he would not be "as bad as he appears."^[46] Evans explained that his character is fun and often acts first and thinks later, which is what gets him into trouble. He added that Theo "has a good heart when you get down to it."^[46] Theo is first seen being pulled over by constable Cash Newman (Nicholas Cartwright) for speeding.

Kerry Harvey of Stuff said Theo "is a far-from-model employee."^[47] The character also comes between young couple Ryder Jackson (Lukas Radovich) and Chloe Anderson (Sam Barrett).^[47] Evans told Harvey that he believed Theo would redeem himself, especially as there were many secrets still to come out, including his relationship with his father and some things he has tried to keep hidden. He added "It will take time, but the audience will learn why he is the way he is and then they will become a little bit forgiving of him."^[47] Coco reprised his role as Theo's father Dimitri in April 2022.
