POLICE seized $25 million worth of methamphetamine hidden in a car near Northam on Wednesday.
Police also found 280 grams of cocaine, $13,500 cash and a semi-automatic pistol in the car.
WA Police Commissioner Chris Dawson said “the seizure represents a very serious disruption” to organised crime.
The methamphetamine was allegedly hidden in the rear compartment of a Toyota Hilux.
“It was a comprehensive concealment,” Mr Dawson said.
A 43-year-old man from NSW is facing five drug- and weapon-related charges.
He is due to appear before the Perth Magistrates Court on Thursday.
A female passenger was also in the car, which was travelling from NSW to WA. She has been released.
WA Police have seized 1.4 tonnes of methamphetamine in the past 12 months.
The bust was a telling blow to organised crime, Mr Dawson told reporters.
“We must interrupt the supply chain,” he said.
He said WA Police’s work was interrupting international, national, suburban and regional syndicates.
“We know the scourge that meth causes to our community,” he said.
“This is a very successful interruption.”
WA Police also released new details of Operation Actum, which began in April and was designed to directly target methamphetamine in WA communities.
The operation has resulted in 407 search warrants, 158 arrests and 1670 charges.
Three kgs of meth, 92 kgs of cannabis and 39 guns were also seized.
