Janette Fay Livermore is behind bars in a women's prison after she caught the eye of police when she crashed her car while drunk in Tamworth.

The 47-year-old appeared in Tamworth Local Court on Monday where she pleaded guilty to high-range drink driving and never holding a licence.

Livermore has been in custody since Friday night after she was arrested in Anthony Road.

Magistrate Julie Soars denied Livermore bail, ordering her to remain in custody ahead of sentencing next month.

Ms Soars ordered medical assessments be carried out, along with a background report for sentencing by Community Corrections. Authorities will also determine if Livermore is eligible for a diversionary program, outside of custody.

Livermore will be sentenced in July.

In unrelated charges, Livermore also admitted to DV-related assault, behaving in an offensive manner, and two counts of contravening an AVO.

Police were called to the Anthony Road home shortly after 4.30pm on Friday after reports a car had hit a house.

Witnesses called police after Livermore got behind the wheel of the Ford Falcon and lost control.

Police claimed Livermore reversed harshly out of the driveway across Anthony Road before mounting the gutter and crashing into the house.

Police said it was miraculous that no one was injured with several children in the street who were playing on the roadway at the time.

Ambulance paramedics were called to assess Livermore as a precaution.

She failed a roadside breath test and was arrested and taken to Tamworth police station. It was there that Livermore recorded a blood alcohol reading of 0.369 - more than seven times the legal blood alcohol limit.

The high reading has astounded senior police, with the level believed to be one of the biggest the city has recorded.

Livermore was charged with driving with a high-range PCA and driver never licensed, and refused bail by police, and subsequently by the court.

She will return to court in July for sentencing.
