Bega Local Court Magistrate Doug Dick sentenced 42-year-old Vivien Jean McCarthur on Tuesday, July 9 to a two-year community release order with supervision and recorded a conviction after her deception cost $30,000 worth of public resources.

The court heard McCarthur had consumed as much as two bottles of vodka the first night and two bottles of wine the second night.

"Self-intoxication is no explanation," Magistrate Dick said during sentencing.

In the early hours of May 11 McCarthur told police she had been outside her home when an unknown male attempted to choke her and held a knife to her throat before attempting to stab her with a knife in the stomach.

She provided a lengthy statement to police, stating the man had wanted to kill her, pushing the knife through her pajamas.

Police officers from Goulburn investigated the scene along with six local officers, and organised alternative accommodation for McCarthur and her children.

The following day she contacted police multiple times to check on the progress of the investigation, and at 9.30pm again called emergency services.

She told police she had heard a car outside and while investigating had been stabbed in the stomach by an unknown man, leaving a one centimetre deep cut to her abdomen.

During a later interview with police one of her children said they had heard McCarthur sharpening a knife in the kitchen before police arrived and had not heard any screaming.

After being taken to Bega's South East Regional Hospital by the only three ambulance officers on the Far South Coast at the time, a helicopter was called to transfer McCarthur to Canberra Hospital.

When her condition stabilised and the transfer was no longer needed, the helicopter remained stuck at SERH until the following day due to bad weather and was unable to respond to other patient transfers across the state.

Three days later McCarthur told police she had been "intoxicated and hallucinating from alcohol" and had lied about the events of May 11 and 12.

She said she "felt bad" and police noted she seemed remorseful for her actions.

Police prosecutors estimated the cost of the "extraordinary misuse of public resources", which included 15 police officers, the flight crew and ambulance crew, at $30,000.

Her defence lawyer Adam Lineham said his client, who had no previous criminal record and suffers from mental health issues, had "acted out of character".

"She was not in her right mind on that night," he said.

He requested his client not be convicted as part of the release order, as she was "remorseful and sorry for her actions".

Police prosecutor Sergeant Liza Brown said McCarthur's behaviour showed "a level of planning and dishonesty".

"This is an offence that goes to the heart of what police do," she said.

"It was an extraordinary misuse of public resources over a number of days.

"There was a large level of dishonesty in this matter."
