A Terang woman accused of trafficking cannabis, while on a corrections order for the same offence, has been arrested and remanded in custody.

Fiona Wright, formerly Hull, 48, of Escort Street, appeared in Warrnambool Magistrates Court on Tuesday charged with trafficking cannabis, negligently dealing with proceeds of crime, possessing ammunition and possessing a prohibited weapon.

In an emotional self-represented bail application, Ms Wright said she had five children, including two sons who were currently in jail and another that was addicted to methamphetamine.

She admitted to smoking cannabis but denied selling it, stating that she "wasn't doing anything wrong".

Magistrate Mark Stratmann refused bail after the woman failed to show exceptional circumstances why she should be released from custody.

Ms Wright broke down in tears and yelled: "Thankyou for sending me to jail".

She was remanded in custody and will appear in court again on April 21.

Senior Constable Rebecca Wills, of the Warrnambool police division response unit, said a search warrant was executed on Tuesday morning involving the DRU, Corangamite uniform police members, Warrnambool crime investigation unit detectives and a police dog.

She said officers seized 180 grams of cannabis, a set of digital scales, a cannabis plant more than one metre tall, a bag containing cannabis stems and leaves, a home-made taser, two shot gun rounds, a set of nunchucks and $2875 cash.

The court heard a preliminary analysis of the woman's phone revealed multiple people had contacted her between September 2019 and yesterday asking to buy coffee and milk.

"We believe that is code for coming around to pick up amounts of cannabis," Senior Constable Wills said.

During a police interview, Ms Wright allegedly said she withdrew money from her superannuation fund to buy seven ounces of cannabis for $1400.

She told police the drugs were for person use and the cash was withdrawn in order to pay a barrister for an unrelated court matter.

Police requested that anyone with information about drug activity contact Crime Stoppers on 1800 333 000.
