The Family Next Door ABC: Story, Cast, Plot Twist & Review

You finally sit down to watch a new Australian drama and within ten minutes you’re checking who lives at the end of that cul-de-sac. The Family Next Door landed on ABC on August 10, 2025, based on Sally Hepworth’s novel, and it’s already pulling viewers into a suburban labyrinth of secrets and suspicion.

Premiere date: August 10, 2025 ·
Network: ABC Television (Australia) ·
Based on: Novel by Sally Hepworth ·
Lead actress: Teresa Palmer

Here is a quick reference to the key details of the series.

What is the story behind The Family Next Door?

Synopsis of the ABC series

• A stranger named Isabelle moves into a small coastal Victorian town called Pleasant Court (ABC iview synopsis)
• She is driven to solve a mystery that involves four neighbouring families (Digital Spy)
• Her obsessive investigation casts suspicion on everyone in the cul-de-sac

Each episode focuses on a different resident while the deeper mystery unfolds. Isabelle’s arrival triggers a chain of revelations about infidelity, hidden identities, and past trauma.

The implication: The series uses the confined setting of a seaside cul-de-sac to explore how easily trust fractures when someone brings a secret into a closed community. The catch: This slow-burn approach won’t suit everyone, but the payoff is deliberate.

Comparison with Sally Hepworth’s novel

• Novel published in 2018, set in Melbourne’s suburbs (Wikipedia)
• TV adaptation moves the setting to a coastal town
• New characters added, including Detective Dom Ona Ariki’s role
• Core mystery remains faithful to the book, but pacing changes

The trade-off: Viewers who have read the novel will recognise the central twist but may appreciate the expanded subplots that give supporting characters more depth.

Is The Family Next Door worth watching?

Critical reception and reviews

“The series underwhelms because the stakes never feel high enough for the characters’ dramatic reactions.” — The Guardian (Australia)

The Guardian review of August 2025 gave the series 3 out of 5, praising the performances but noting that the plot sometimes feels stretched. ScreenHub’s review was more positive, calling it “great TV” and emphasising the episodic structure.

The catch: Critics agree the series looks gorgeous (Victorian coastline) but disagree on whether the mystery justifies six hours.

Audience opinions from Reddit and IMDb

“The production value is incredibly high for an Australian TV show. The coastal setting really adds to the atmosphere.” — Reddit user (r/ausTV)

On Reddit, viewers praise the acting and setting, with some calling it the best local drama of 2025. IMDb as of late 2025 shows a rating of 7.1/10 based on under 1,000 votes (IMDb).

Why this matters: Early audience sentiment suggests the series may improve its reputation as more viewers binge it on iview.

Is The Family Next Door on ABC based on a true story?

Inspired by real events?

No. The series is purely fictional. Sally Hepworth’s author site confirms the novel is her original work, not based on any real crime.

Fictional origins confirmed

• ABC’s official description never claims true story status
• News reports from Digital Spy explicitly label it a fictional drama
• Wikipedia lists it as an adaptation of Hepworth’s novel, not a true crime reenactment

The pattern: It’s common for suburban thrillers to be mistaken for true stories; The Family Next Door purposefully avoids that marketing angle.

Where is The Family Next Door filmed in Australia?

Filming locations in Victoria

• Principal photography took place in Victoria, Australia (ScreenHub)
• Specific coastal towns: locations near the Great Ocean Road and the Bellarine Peninsula
• The fictional Pleasant Court was built as a set on location, not a real street

Representation of a coastal town

The series uses the ocean and lush greenery to create an idyllic backdrop that contrasts with the characters’ inner turmoil. Digital Spy notes the setting is intentionally ambiguous to feel like any small Australian beachside community.

The catch: While the locations are beautiful, the show deliberately avoids naming the exact town to keep the mystery self-contained.

What is the plot twist in The Family Next Door?

Major spoilers and reveals

Spoiler warning: The final episode reveals that the person Isabelle has been searching for is her own daughter Mia, who was taken from her years ago. The twist is that Mia has been raised by one of the neighbouring families without knowing her true parentage.

• The identity of Isabelle’s missing person is Mia (Wikipedia)
• Mia’s parentage is the central secret – she is Isabelle’s biological daughter
• The final episode resolves the mystery but leaves emotional consequences open

Whose daughter is Mia?

Mia is the daughter of Isabelle and a man from Isabelle’s past, not the child of the family she lives with. This is the dramatic reversal that changes everyone’s understanding of the characters’ relationships.

The implication: The show uses the “found family” trope to examine whether genetics or upbringing defines a parent-child bond.

“ScreenHub says the series ‘makes for great TV’ because it uses the cliffhanger-per-episode structure that keeps you coming back.” — ScreenHub review

For Australian viewers who enjoy homegrown drama with a psychological edge, The Family Next Door offers a solid binge over a weekend. For those expecting a fast-paced crime thriller, the slower burn may test patience. The decision for ABC executives is clear: a second season depends on whether iview viewing numbers justify the production cost, given the mixed critical reception.
