A routine intercept in Keilor East led to police seizing around one kilogram of cocaine on Saturday.
Keilor Downs police were patrolling Slater Parade when they came across a vehicle which flagged for having an active Firearm Prohibition Order about 6pm on 11 May.
Officers intercepted the car and a subsequent search of it located approximately one kilogram of what is alleged to be cocaine, as well as $2450 in cash.
The seized amount has an estimated street value of $300,000.
The driver - a 40-year-old man from Wollert - was arrested and later charged by Brimbank Divisional Response Unit detectives with trafficking a commercial quantity of a drug of dependence.
He appeared before Melbourne Magistrates' Court on Monday and was bailed to appear again on 5 August 2024.
An FPO prevents a person from acquiring, possessing or using a firearm or firearm related items, as well as entering certain premises such as firearms dealerships and shooting ranges.
As the order is linked directly to the person, not a specific location, police can search an FPO subject's vehicle or property at any time.
Anyone with information about drug trafficking is urged to contact Crime Stoppers on 1800 333 000 or submit a confidential report online at www.crimestoppersvic.com.au
