Nicole Margaret Bruce had pleaded not guilty to wounding Tara Lee Roberts outside the Tapas Lounge Bar in the early hours of September 21 last year.

In the Supreme Court, in Burnie, yesterday, Crown prosecutor Allison Shand told jurors she did not think they would have any doubt Ms Roberts was wounded, or that Ms Bruce caused it.

In her closing address, Ms Shand argued jurors could be satisfied Ms Bruce intended to wound Ms Roberts, or foresaw a wound was likely.

The incident took place shortly after Ms Bruce was escorted from the venue by security, the court heard.

Ms Shand said Ms Bruce had been involved in a fight inside the venue with another female patron.

Ms Shand suggested Ms Bruce may have thought Ms Roberts was that woman, or may simply have acted out of aggression.

Katie Edwards, for Ms Bruce, said her client clearly had no memory of the incident.

The record of police interview showed Ms Bruce was horrified and extremely remorseful when the allegation was put to her, Ms Edwards said.

Justice Helen Wood told Ms Bruce a sentence of actual imprisonment was inevitable.

She was remanded in custody to next appear, in Hobart, on July 25.
