Brianna Meizer, 28, was the first person involved in Strike Force Pinnacle to be sentenced in Dubbo Local Court on Tuesday.

According to court documents the operation's police surveillance activities revealed Meizer's involvement in the syndicate, which saw more than 30 people charged over a large-scale drug supply network operating from Wellington.

In June 2019, Meizer was contacted by someone called "Tegan" from Mudgee who requested a "full ball" of ice, which police said equated to 3.5 grams of meth.

After this request, Meizer contacted three men - all involved in the syndicate - and in one conversation said she couldn't access the room where the drugs were kept as she didn't have a key.

She then organised the woman to pick up the men and take her to the room to access the drugs.

Court documents revealed that Meizer was contacted again the next day and asked to supply more ice. She told one of the co-accused she was at the TAB, but could go home if required.

Meizer later sent a text saying she "had 3 I gave her half one so she owe me 15 now [sic]", which police said meant 1.75 grams of ice was exchanged for $300.

A few weeks later, court documents said the alleged senior member of the drug syndicate instructed Meizer to supply three grams of ice for $200.

In other phone interceptions police said Meizer was heard discussing the price of "bupe" strips with other members of the drug syndicate, and ways drugs could be smuggled to her partner in jail.

Earlier this month Meizer pleaded guilty to one count of supplying 8.25 grams of methylamphetamine and one count of participating in a criminal group and contributing to criminal activity, in Dubbo Local Court.

Defence lawyer Rachel Waugh said Meizer was a mother of two. She was supported in court by her own mother and father.

Ms Waugh said Meizer had spent four months and 24 days in custody and completed a voluntary program for people with drug and alcohol issues.

A letter of apology from Meizer, a merit report, sentencing assessment report and drug test were tended in court.

"She was bail refused and it was the first time she'd spent time in custody," Ms Waugh said.

"She experienced significant hardships during that period of time time it occurred during that COVID period. She did not see her children. She says it was certainly a wake up call."

The court heard Meizer's criminal record included a prior conviction for prohibited drug possession.

"At the time of the offending conduct, she was someone who was heavily involved in a drug addiction herself," Ms Waugh said.

"She has continued the abstinence of the illicit substances."

Magistrate Theresa Hamilton accepted Meizer had taken "substantial steps" toward rehabilitation.

"No doubt she actively took part in this group and the supply of drugs."

According to the sentencing assessment report, Meizer's criminal history was "limited" and had assed her at a medium risk of reoffending.

"The sentencing assessment report refers to the alleged influence of then partner at the time," Magistrate Hamilton said.

Meizer was convicted and sentenced to a 12-month term of imprisonment, to be served in the community as an intensive corrections order.

She was also ordered to complete 90 hours of community service work.
