Police seized the cash from inside a backpack found at the home of Jordyn Lea Fenton, 26, in November last year.

On Friday the Launceston Supreme Court heard Fenton initially lied to police and claimed the cash was hers.

A man Fenton worked for had given her the money to look after and during a three-month period the court heard Fenton delivered wads of cash to the man when he requested it.

Fenton admitted to police she suspected the money came as a result of drug deals.

The court heard Fenton told police she lied about the money being hers because she was scared of the man who had asked her to stash the cash.

Defence counsel Fran McCracken said Fenton had a good record, held down jobs and pleaded guilty at the first available opportunity.

Justice Robert Pearce said while it was not asserted that Fenton played any part in the sale of drugs, a sentence of imprisonment had to be imposed because the amount of cash was "so large" and "so obviously proceeds of a crime".

"The conduct you engaged in is wrong because by agreeing to hold the money, you facilitated the criminal conduct which produced it and you assisted the perpetrator to attempt to hide his criminal conduct so as to avoid apprehension and punishment," Justice Pearce told Fenton.

"Even if it may have been difficult, and though you were used and manipulated, your duty was to refuse."

Fenton wept in court as she was sentenced to a 10-month term of imprisonment, wholly suspended for two years.
