A 20-year-old Timboon man has been charged with trafficking three different illicit drugs after police found more than $40,000 in cash during a raid at his home.

Detective Senior Constable Ross Hatton, of the Warrnambool police crime investigation unit, said officers executed a Drugs, Poisons and Controlled Substances Act search warrant at a Timboon residential address about 8am Wednesday.

Investigators from the Warrnambool CIU were backed by uniform officers from Port Campbell, Camperdown and Timboon stations.

They found about 15 grams of cannabis as well as smaller amount of amphetamine and ecstasy.

In addition more than $40,000 in cash and two imitation firearms were located in the home.

Detective Senior Constable Hatton said the imitation firearms were gel blasters.

"These items are available for sale on the internet, but they are classed as a firearm and they are illegal," he said.

"During early July the 20-year-old Timboon man that we arrested today dialled into a prison Zoom call and showed an inmate a gel blaster.

"Vision of that blaster raised concerns with prison staff because it looked like the real thing. That information was passed on to us and led to the execution of the warrant.

"We were there for the firearms, so uncovering that range of drugs and, in particular that amount of cash, was a big surprise.

"It's been an excellent result."

The Timboon man has been charged with being a prohibited person in possession of firearms, trafficking cannabis, amphetamine and ecstasy and possessing the proceeds of crime - the cash.

He appeared in the Warrnambool Magistrates Court on Thursday and was remanded in custody until August 7. He will be assessed for the bail-support Court Integrated Services Program in custody.

Earlier: About $40,000 in cash was located in a Timboon home early Wednesday morning after a police drugs raid.

Members of the Warrnambool police crime investigation unit executed a search warrant at a Timboon property earlier today.

They found a couple of ounces of cannabis, as well as ecstasy, methamphetamine and about $40,000 in cash.

A Timboon man in his 20s has been arrested and is currently being conveyed back to the Warrnambool police station where he will be interviewed by detectives.

Detective Senior Constable Ross Hatton said investigators were still in the initial stages of their inquiries.

"The execution of a warrant under the Drugs, Poisons and Controlled Substances Act this morning has led to the seizure of a number of items, including a range of illicit drugs," he said.

"We've also located about $40,000 in cash. It's a significant find."

It's expected the Timboon man will be interviewed and charged with a range of offences today.

He may also appear in the Warrnambool Magistrates Court for a bail/remand hearing later today depending on how the investigation unfolds.
