Development Introduction
Bianca's casting in an unnamed guest role was announced via a press release issued by Amazon MGM Studios in the United States.

The show officially announced the casting and character details on 14 January 2024. Chelsea is named after the Neighbours crew member Chelsea Chua. Bianca revealed that the part of Chelsea is an extended guest role. In a backstage video, she stated "Chelsea sticks around for a while and has quite a bit of business to tend to, and is determined to do so." Bianca described Chelsea as "a really effective manipulator" and has ulterior motives behind her actions. Bianca added that Chelsea has "always got something else kind of ticking." One of Chelsea's introductory stories involve her romantic pursuit of businessman Paul Robinson (Stefan Dennis). Bianca described Chelsea as "a woman who has a serious agenda and very, very ambitious hopes for her life and sees them through Paul." Dennis added that "it's very blatant that Chelsea is seen as a gold-digger" during her introduction scenes. Bianca revealed that Chelsea would create "major trouble for other people but then in turn herself and she then needs to cover her tracks. And we see lies upon lies and she's burying herself in a hole. And in doing so she becomes quite vulnerable I think and it all becomes very messy for Chelsea."
Susannah Alexander from Digital Spy reported that Chelsea claims to be in Erinsborough to retail her new perfume in Melbourne. She also detailed Chelsea's secret interest in Paul, which is revealed in her introductory scenes. Writers portrayed Cara as delighted to have Chelsea around, but Cara's wife Remi Varga-Murphy (Naomi Rukavina) is annoyed by Chelsea's presence but Cara is defensive over her behaviour. Remi becomes concerned that Chelsea offers relationship advice to her teenage son, JJ Varga-Murphy (Riley Bryant), after he shows interest in the older Sadie Rodwell (Emerald Chan). Chelsea also befriends Cara and Remi's new friends David Tanaka (Takaya Honda) and Aaron Brennan (Matt Wilson).
Relationships and scheming Digital Spy's Daniel Kilkelly revealed Chelsea would begin scheming to get closer to Paul. She becomes annoyed when Paul is distracted by his ex-wife, Terese Willis (Rebekah Elmaloglou). Chelsea decides to give herself a make-over inspired by Terese's style to gain Paul's attention. Her plan begins to work as Paul takes notice of her. Bianca enjoyed working on the storyline with Dennis because she had watched the character's stories when she was young. She added "now I'm on set, going head to head with Paul Robinson and working with Stefan almost every day." Advance episode spoilers revealed that Chelsea would continue to be central the show's dramas. This included taking advantage of a grieving Paul after the death of his son David, installing herself as the manager of Lassiters Hotel and feuding with Krista Sinclair (Majella Davis).
Writers developed the rivalry between Chelsea and Paul's ex-wife, Terese, which ends in a confrontation. Chelsea takes revenge by sabotaging a memorial plaque dedicated to Terese's dead son, Josh Willis (Harley Bonner). Chelsea conceals the plaque in rubbish and ensures it is disposed of. Bianca told a TV Week reporter that Chelsea is "triggered" by Paul and Terese's bond. Chelsea realises that Paul and Terese's common experience of losing a child threatens her schemes. Bianca explained that Chelsea is "worried" that she will lose Paul to Terese. She also views Terese as "a successful older woman who has built a robust business for herself – exactly what Chelsea aspires to." Bianca added that Chelsea wants the "financial security" Paul offers, but Chelsea is "falling for Paul" and wants a "genuine and romantic" future with him. She concluded that the confrontation with Terese is a "sucker punch" for Chelsea to overcome. Dennis revealed that "there is this genuine affection underneath" and questioned whether the feelings were "strong enough to create longevity." Elmaloglou and Dennis told a Virgin Radio UK interviewer of their shock at how quickly the show's producer Jason Herbison developed two separate "love triangle" stories which merge into one complicated love entanglement. One features Terese, her husband Toadie Rebecchi (Ryan Moloney) and his ex-wife Melanie Pearson (Lucinda Cowden) and the other features Terese, Paul and Chelsea. Elmaloglou told the radio host that "Paul's got Chelsea and yeah, I think you know, we all love a bit of drama, and we expect it when we work on a show like Neighbours." When Toadie betrays Terese by having sex with Melanie, Paul sees this as an opportunity to grow closer to Terese. Dennis told Ellis (Inside Soap) that Paul's relationship with Chelsea is "the only problem" stopping him from pursuing Terese. He is doing a "juggling act" trying to figure out how to be with both Chelsea and Terese. Elmaloglou added that Terese initially lets Paul spend time with Chelsea instead of being overly reliant on him.
Writers continued displaying Chelsea's scheming when she concocts a plan to become pregnant with Paul's child. Chelsea decides to enact her plan after realising that Paul values family in his will. She faces difficulties in her attempts to become pregnant after Paul dismisses the seriousness of their relationship. Dennis commented that if Chelsea did become pregnant, then Paul "would be really happy." Chelsea becomes enraged when Paul's sister, Lucy Robinson (Melissa Bell) chooses Krista to present an important business meeting. A Neighbours publicist revealed that "Chelsea sees red" and wants to take over the presentation. They added that Chelsea "goes to great lengths to make that happen." Chelsea also continues to manage Lassiters, and repeatedly tries to undermine her rival, Krista. A TV Week reporter revealed that Chelsea's jealousy over Paul heaping praise on Krista leads her to make a drastic move, which leaves both Krista and her unborn baby in danger. Chelsea locks Krista in a sauna so she can take her place in a work presentation, leading Krista to collapse and lose her unborn baby.
Writers explored Chelsea and Krista's rivalry over the following episodes. Bianca told Sarah Ellis from Inside Soap that "Chelsea feels threatened by Krista's power." Chelsea envisions herself and Paul as a "power couple" and wants to "shine at Lassiters" to achieve her this. Bianca noted that "Krista already possesses what Chelsea so desperately wants" and she is "envious" of her. She defended her character's behaviour, noting "Chelsea is riddled with guilt" about Krista's miscarriage and it was unintentional that the situation becomes so "awry". Chelsea is also "terrified" about her actions being exposed, likening Chelsea's predicament to a "domino game she's lost total control of." Bianca assessed that it showcased how "extreme" Chelsea is but ultimately she really needs her relationship with Paul to work or "she will land back on her ass". A co-dependent dynamic was written for the characters, as they become reliant on each other to hide their secrets. Bianca described that "they become strangely co-dependent" and "they hold the key to one another's Achilles heel." Chelsea later takes advantage of Krista's grief and tempts Krista into taking drugs. Inside Soap's Ellis reported that Krista would be unaware that Chelsea purposely caused her drugs relapse. Bianca worried that her character's schemes were out of control in this plot and hoped for a redemption story arc. She hoped that Chelsea would achieve her goals of snaring Paul's livelihood and become the "power couple".
Additional spoilers revealed Chelsea's ruthlessness to keep her secrets from being revealed to Paul. The arrival of IT technician Jeffrey Swan (Tim Potter) panics Chelsea, as he has a report on the events leading to Krista's collapse. Jeffrey's report directly implicates Chelsea in the incident. Chelsea becomes determined to convince Jeffrey to doctor his report and makes him an "indecent proposal" in exchange. Jeffrey then pursues a romance with Chelsea, behind Paul's back. Michael Adams from Metro reported that Chelsea is "left embarrassed" because it is "evident" that Jeffrey has "fallen for her".
Departure Chelsea's lies unravelled amidst her engagement to Paul. Kilkelly (Digital Spy) reported that "their relationship finally takes a more serious turn", as Paul asks Chelsea to propose to him and he accepts. Paul's son Leo Tanaka (Tim Kano) suspects that Paul is using Chelsea to get over Terese. A Neighbours publicist told Inside Soap's Chloe Timms that Chelsea feels accomplished and has got everything she "worked so hard for - and she's relishing every second". The publicist added that "Krista now knows every horrifying thing Chelsea has done in Erinsborough." They added that "Chelsea's house of card is set to fall" at the exact same time.
Kilkelly reported that Chelsea would have a "nasty shock" as "her luck finally runs out". He added that Chelsea and Paul's engagement party would be ruined by Jeffrey and Krista, after the latter realises "her rival's terrible secret". In a backstage video, Bianca revealed that Chelsea and Paul's engagement party took one day to film. She added that it began "on a high" but ends "tragically, especially for Chelsea." In the aftermath of the reveal, Paul is "thrown into turmoil as he finally realises what Chelsea is capable of." The revelations also affect Cara, who was shaken by all Chelsea had done. Chelsea "abruptly vanished" from Erinsborough and evaded the pursuit of the police.
