A Mount Morgan drug dealer and producer yesterday had her sentence halved for giving evidence in a murder trial.
"Perhaps it will make more people come forward," defence barrister David Murray said.
Naomi Sophia Phillip, 32, pleaded guilty in the Rockhampton Supreme Court to charges of trafficking, producing and possessing dangerous drugs.
The court heard her offending spanned from December 2009 to August last year.
Crown prosecutor Joshua Phillips said the defendant was able to source large amounts of methylamphetamine and sell it for "not unsubstantial money".
He said police also located meth labs she was responsible for.
The court heard Phillip gave evidence in the murder trial of Rockhampton's Kerryn Ann Young and Bradley David Hill in June this year.
The couple was found guilty of murdering Gladstone man and meth addict Luke McAuliffe in 2010.
Mr Murray said his client, who has been in custody for the past 15 months, had been "bashed" by a fellow inmate since the trial.
"She lives on the edge all day every day," he said.
Justice Duncan McMeekin said Phillip's evidence in the trial had been "compelling".
He reduced her head sentence from eight years to six and set a parole eligibility date at August 14 next year.
