Netflix’s 2026 survival thriller Thrash doesn’t just rely on high-stakes performances and relentless pacing — its filming locations do a serious amount of storytelling heavy lifting. While the film is set in a fictional South Carolina coastal town battered by a Category 5 hurricane, the reality behind the camera is far more grounded, with most of the production rooted in Australia.
At the same time, not every location has been publicly disclosed, a deliberate move to keep production secure and avoid disruptions during filming.
Directed by Tommy Wirkola, Thrash throws viewers straight into a collapsing coastal community where rising floodwaters meet a far more dangerous threat lurking beneath — sharks.
The film leans heavily on its environments to build tension, and that realism comes from a carefully chosen mix of urban, coastal, and studio-based locations.
Melbourne, Victoria becomes the backbone of Thrash, doubling convincingly as a storm-ravaged American town. Large-scale outdoor sequences were filmed across the city, where production teams transformed familiar streets into flooded disaster zones.

The choice of Melbourne wasn’t accidental — its versatile cityscape allowed filmmakers to recreate both suburban calm and chaotic destruction within a controlled environment.
Cast member Amy Mathews later described the shoot as one of the biggest productions she had worked on, hinting at the scale behind those sequences.
Docklands Studios in Melbourne plays a critical role in shaping the film’s most intense moments, particularly the hurricane and shark sequences.
The production relied on its advanced water tanks and custom-built sets to simulate violent flooding and underwater tension.
These controlled environments allowed the crew to blend practical effects with digital enhancements, especially in scenes involving shark encounters.
Phoebe Dynevor, who portrays Lisa, revealed that filming in those tanks during Melbourne’s winter pushed the cast physically, with freezing conditions adding an unexpected layer of realism to their performances.

In contrast, Canterbury offers a quieter but equally important backdrop, standing in for residential neighbourhoods caught in the storm’s path.
The suburb’s clean streets and upscale homes were gradually transformed into disaster zones, creating a stark visual shift as the hurricane narrative escalates.
These scenes ground the story emotionally, showing what’s at stake for the town’s residents before chaos fully takes over.
Mount Macedon introduces a different visual tone altogether, delivering sweeping environmental shots that heighten the sense of isolation and impending danger.
Its rugged terrain and dense greenery help establish the scale of the storm beyond the town itself, giving audiences a broader view of the natural forces at play.
The location’s cinematic landscapes are used to build tension before the story returns to tighter, more claustrophobic settings.

Mornington Pier, located along the Mornington Peninsula, becomes the film’s key coastal anchor, representing the shoreline where the disaster truly unfolds.
With its open water views and weathered structures, the pier provides an ideal setting for scenes involving rising tides and ocean-based threats.
It’s here that the film’s central premise — survival against both nature and predators — feels most immediate.
Beyond Australia, the internet has latched onto rumours surrounding the Chicago River as a possible filming site, though nothing has been officially confirmed.
Viral clips circulating online appeared to show staged flood conditions and artificial shark props in the water, sparking widespread speculation.
While these sightings added an unexpected layer of intrigue to the film’s production story, they remain unverified, and official sources continue to point firmly towards Victoria as the primary filming base.
To further support the film’s large-scale visuals, areas surrounding the Mornington Peninsula — including nearby coastal stretches often used in Australian productions — are believed to have contributed additional environmental shots.
These neighbouring locations help extend the illusion of a vast, interconnected coastline under threat, even if not all have been formally credited.
Fan reactions to the filming locations have been mixed but undeniably engaged, with many praising how convincingly Australia stands in for an American coastal setting.
Some viewers expressed surprise upon learning the truth behind the locations, admitting they initially assumed filming took place in the United States.
Others have been more focused on the technical side, applauding the seamless integration of practical water effects and digital sharks.
Meanwhile, the Chicago River rumours have taken on a life of their own, with netizens debating whether the clips are genuine behind-the-scenes footage or simply clever misdirection.
One Melbourne local shared online that spotting parts of the city transformed into a disaster zone felt surreal, especially knowing those same streets are usually calm and familiar.
That sense of recognition has added an extra layer of enjoyment for audiences who can connect the fictional chaos with real-world locations.
Another viewer joked that after watching Thrash, they’d never look at coastal holiday spots the same way again — a reaction that perfectly captures the film’s lasting impact.
Whether it’s Melbourne’s urban streets, Mornington’s coastal edges, or the rumoured sightings elsewhere, Thrash has turned its filming locations into part of the spectacle.
With some locations still under wraps, there’s every chance more behind-the-scenes details will surface in the coming months.
So if you’re already planning a trip inspired by Thrash, or just curious about where fiction meets reality, keep watching this space — and feel free to weigh in: which location would you visit first, and did any of them genuinely surprise you?
