Chelsea Murphy is a fictional character from the Australian television soap opera Neighbours, played by Viva Bianca.

Despite her short tenure, Chelsea's characterisation made her a "divisive character" with viewers generating many differing reactions.

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

"[4] One of Chelsea's introductory stories involve her romantic pursuit of businessman Paul Robinson (Stefan Dennis).

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).

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).

[9] Chelsea takes revenge by sabotaging a memorial plaque dedicated to Terese's dead son, Josh Willis (Harley Bonner).

[11] 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.

Dennis told Ellis (Inside Soap) that Paul's relationship with Chelsea is "the only problem" stopping him from pursuing Terese.

"[5] Chelsea becomes enraged when Paul's sister, Lucy Robinson (Melissa Bell) chooses Krista to present an important business meeting.

Bianca told Sarah Ellis from Inside Soap that "Chelsea feels threatened by Krista's power.

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".

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".

Inside Soap's Ellis reported that Krista would be unaware that Chelsea purposely caused her drugs relapse.

The arrival of IT technician Jeffrey Swan (Tim Potter) panics Chelsea, as he has a report on the events leading to Krista's collapse.

Kilkelly (Digital Spy) reported that "their relationship finally takes a more serious turn", as Paul asks Chelsea to propose to him and he accepts.

[22] 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".

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".

[26] Bianca wrote a post on her Instagram account revealing that her guest stint on the show had ended, stating "thank you for welcoming me into the Neighbours family.

"[25] On 5 December 2024, a writer from Inside Soap revealed that Chelsea would return in scenes featuring her and Cara at an airport.

[31] On 1 January 2025, Neighbours' executive producer Jason Herbison revealed more details about Chelsea's return in an interview with Johnathon Hughes from Radio Times.

"[32] The airport scenes are due to be revisited through flashback on 6 February, revealing that Cara spoke to Chelsea and refused to support her.

Chelsea helps to plan David's funeral to support Paul, but this angers Leo Tanaka (Tim Kano), who accuses her of being a gold-digger.

Chelsea enacts revenge by ensuring a memorial plaque dedicated to Terese's dead son, Josh Willis (Harley Bonner), is disposed of.

Chelsea gets paranoid when she starts losing control of the hotel, and tries to sabotage Krista's Lassiters Longest Lie-In event by changing the staff rosters.

"[8] Their colleague, Michael Adams added that Chelsea made "vile decisions" during her tenure and her scheming against Krista was "a further cruel act".

[38] Digital Spy's Kilkelly branded Chelsea as "Cara's charming sister" who is "never one to pass up an opportunity" and was "laser focused" on seducing Paul.

[7] His colleague, Stefania Sarrubba branded her a "schemer" and that Bianca gave a "complex performance as one of the series' villains.

"[42] Ellwood-Hughes branded Chelsea a "dastardly character" and "a master of covering her tracks", adding that her characterisation made it certain she would find "another unsuspecting person to target and manipulate".
