Kane Kennett, 25, of Kauri Crescent, pleaded guilty in Warrnambool Magistrates Court to drug and weapon-related offences.

The court heard on October 21 last year, police seized Kennett's phone during a search warrant and located numerous messages referring to the sale of drugs, as well as pictures of firearms.

That led police to execute a search warrant at his home on November 11.

Officers located a book with hand-written notes that revealed that between August 24 and November 12 last year, Kennett sold $39,292 worth of drugs of dependence.

A second search warrant at a separate property uncovered an unregistered 12 gauge shotgun and a .22 rifle hidden in a cavity behind a shower.

The firearms were the same as those located on Kennett's phone in October.

The court heard the .22 rifle stolen was stolen during a burglary at a property near Ballarat in 2018.

Kennett was arrested, interviewed and released on community corrections order.

Then on December 16, he was the passenger in a blue stationwagon intercepted on Portland's Cape-Nelson Road.

He was found in possession of 10 grams of methamphetamine and 250ml of gamma-hydroxybutyric (GHB) concealed in a sports drink bottle.

At the time of the offending, Kennett was on a corrections order.

Barrister Timothy Sullivan said the corrections report was mixed, stating that his client had attended every appointment but at times was under the influence of ice.

He said since being in custody, Kennett had undertaken a number of courses, was drug-free and "the fittest he has looked for years".

Magistrate Jonathan Klestadt said Kennett was in "tragically similar circumstances to many".

He said when people entered the drug world, they were forced to become drug dealers in order to support their own habits and repay substantial debts.

"It's been happening throughout Victoria for the last 10 to 15 years with amphetamines particularly," he said.

"The story of your descent into this most serious crime of drug trafficking is a tragically familiar one for me.

"You fell into the hands of organised criminal gangs who are only interested in their own profits and through a combination of I suspect threats and the enjoyable nature of drug use, you were convinced to become a part of the supply train of this most terrible damaging substance.

"The trauma which your arrest and imprisonment has caused to your family and friends, and wider circle, is repeated daily around Victoria with enormous consequences."

Mr Klestadt said when Kennett was placed on a corrections order, he was given an opportunity to accept responsibility and turn his life around.

"But the fact that within weeks you were again supplying this terrible substance to the people around you, demonstrates that you had no insight into the serious nature of your conduct," he said.

"The maximum penalty for charge of trafficking methamphetamine in this court is two years jail and today you effectively come before me on two separate sets of this type of behaviour which has netted you in the vicinity of at least $35,000 to $40,000

"I accept that this was largely to pay for your own drug use but there is no doubt at all that you were contributing to the financial resources of these illegal, unlawful, criminal enterprises."

Kennett was sentenced to six months' jail with 105 days already served in custody on remand.

He will be released on a 12-month therapeutic corrections order. He was also fined $500.
