It is a regular Tuesday morning in sunny suburbia. On a quiet street in north Canberra, residents are heading to work while others prune their hedges.
Nearby, a curious group in hi-vis jackets watch as armed police, canine handlers, and Border Force officials quietly flood the block.
Their target? A house that appears ordinary from the outside with a bright yellow SUV parked on the nature strip and a toddler car seat perched on the front porch.
During an exclusive ride-along on September 15, The Canberra Times accompanied ACT Policing as it raided the property believed to be a "drying house" for commercial quantities of cannabis crop.
The search is part of a two-day multi-agency effort by Operation Margate, launched in 2023 to disrupt a Vietnamese crime syndicate said to be behind a sophisticated network of grow houses in the capital.
By 9.35am, the domestic setting has turned into a crime scene as a convoy of law enforcement vehicles rolls up and surrounds the residence within seconds.
From a parked vehicle across the street, a thrice-repeated warning at the front door echoes: "POLICE SEARCH WARRANT!"
Moments later, officers hammer their way into the house and arrest a 44-year-old man, accused of being a crop sitter, or caretaker.
The distinct, earthy smell of cannabis envelops the senses as a walk through the property reveals a meticulous setup.
A room lined with plastic sheets, and a large makeshift vent, stores laundry tubs full of dried cannabis while a fan and heater are aimed directly at a blanket of buds laid out across a wooden drying rack.
"[The smell] gets on your clothes ... we'll be stinking of it by the end of the day," an officer says.
In another room, a mattress rests on the floor alongside a single cupboard where two plastic, mini-greenhouses appear to be storing cannabis seedlings.
Senior Constable Tim, whose last name this masthead has chosen to omit for operational safety reasons, says this is just one of several suburban properties simultaneously raided across the ACT that morning.
In an earlier briefing, he addressed about 80 people involved in the operation including specialist members from the Australian Federal Police, Australian Border Force, and EvoEnergy technicians (who were called to cut off the power supply to each suspected grow house).
Attendees were assigned teams and shown how to uproot and bag cannabis plants a bread knife.
During the man's arrest in Evatt, a live update on the Operation Margate "group chat" confirms other teams have just breached five active grow houses and arrested a 34-year-old woman.
We're not after people that are smoking a joint after work or growing a couple of plants in the backyard. That's not what this operation is about.
The pair arrested on Tuesday are among nine foreign nationals, including four "unlawful non-citizens", accused of links to the syndicate and charged with drug cultivation and trafficking related offences.
Senior Constable Tim said some of the accused crop sitters made money working for the Vietnamese syndicate and some didn't want to be there, while others may have been forced into working for the criminal group.
"I think a lot of them feel trapped, they can't get a job, they don't speak the language ... it's a mixed bag," he said.
The hydra-headed syndicate is notoriously resilient against conventional police methods owing to recruitment tactics rooted in community trust and deep fear.
Detective acting Inspector Mark Battye, the officer in charge of the Drugs and Organised Crime Team, describes it as an endless game of Whac-A-Mole.
"Other grow houses will pop up again," Detective acting Inspector Battye said despite the success of Operation Margate.
The biggest grow house dismantled this week is a four-bedroom property in Franklin where police reportedly found 457 cannabis plants.
Except a dining table in the living room, there appear to be no signs of the house being used as a residence.
All the doors in the property, rife with trip and hanging hazards, only open outwards. The floor of the house is littered with dirt and the bathroom is suspected of being used as a reservoir.
A tall AFP officer, struggling to stand in a tightly packed room of adult and adolescent plants, points out rows of lights used to grow the weed and electrical wiring said to be stealing power from the local grid.
Police believe such risky electrical work, bypassing the meter and fuse, was the reason behind four grow house fires in Isabella Plains, Page, Gungahlin and Chapman between 2019 and 2023.
"Without a fuse to protect them, it's immediate death [for] any postman, delivery person, or kids on Halloween knocking on a metal door frame," Senior Constable Tim says.
Senior Constable Tim and AFP forensic accountant Jess, whose last name cannot be reported for operational safety reasons, tell this masthead the two-day operation was the biggest grow house bust in ACT history.
They reportedly found almost 1600 cannabis plants and about 70kg of dried cannabis with a total street value of more than $7 million.
Operation Margate this week shut down 11 grow houses, including one in Jerrabomberra with the help of NSW police, seized six vehicles and about $86,000 in cash.
"We're not after people that are smoking a joint after work or growing a couple of plants in the backyard. That's not what this operation is about," the senior constable says.
"Cannabis is a commodity that's worth billions of dollars, not just in Australia but all over the world, and that's why this very large transnational syndicate is operating on such a large and successful scale.
Noting that one grow house can have a three-month harvest cycle, he says: "They are making millions ... not paying tax ... there's also more flow-on effects on the community too."
Jess says previous investigations have revealed grow houses being used as cash generators to manufacture and traffic other drugs such as heroin.
She says those who think police are just targeting "plants" are mistaken about the consequences of a large illegal grow house on the economy, rental market and innocent home owners.
It's understood the wealthy syndicate behind these activities is capable of obtaining fraudulent documents and stolen identities from other criminal suppliers, weaving a convoluted web of electronic bank transfers and washing the money through small businesses.
The forensic accountant said such criminals could easily beat regular home buyers when it comes to purchasing a house at an auction or leasing a property through platforms like Gumtree and Facebook Marketplace where their high offers go unrivalled.
She says cutting property managers out of the picture and not doing house inspections every three months is the perfect situation for grow house operators, leaving behind unsuspecting landlords with up to $60,000 in repair costs for electrical work, repainting, and structural renovations.
"It's not a victimless crime," Jess says, adding that police could be watching these setups for anywhere between two weeks and two years.
