A 57-year-old Hamilton man was remanded in custody on Friday night after police conducted a search warrant at his Kenna Avenue address.

Hamilton Police Sergeant Pam Nix said he will appear at Warrnambool Magistrates' Court on Monday.

"Police searched his house and located a traffickable quantity of cannabis at his house," she said.

"He was remanded and charged with trafficking and possession of a drug of dependence."

A traffickable quantity of cannabis generally equals 250 grams or over, or 10 plants.

The penalties often are much higher for trafficking an illegal drug and depend on quantity and a person's age.

The maximum penalty for an adult is 15 years jail and/or a fine of up to 1,800 penalty units, or 25 years jail and/or 3,000 penalty units for trafficking a commercial quantity of an illegal drug.
