The former fiance of billionaire James Packer now lives on $100 a week.

Tziporah Malkah appeared in court on Friday to plead guilty after a night of erratic driving in Melbourne when she reversed into a parked car.

Malkah, 44, the model formerly named Kate Fischer, was seen hitting three roundabouts in Toorak about 5.35pm on January 3.

One person followed her and called triple zero before Malkah reversed into a parked car, Melbourne Magistrates Court heard.

Police soon arrived at her apartment and asked her five times to do a breath test, but Malkah said she needed to go to the toilet and disappeared inside.

Her lawyer Michael Kuzilny said the star of the 1994 film Sirens was "very financially disadvantaged" and was ripped off in a $2 million Los Angeles real estate scam some years ago.

He said she lives on a pension of $200 a fortnight.

Mr Kuzilny said Malkah returned to Australia in 2000, broke, and lived for a time in a women's shelter where she completed a certificate in community service.

"Friends and family say it's very much out of character for her," he said.

"She's very remorseful and wishes to give the court some confidence there will be no repeat behaviour."

Malkah was fined $1500 and had her drivers licence suspended for 27 months.

After a previous court appearance, Malkah - who wants to become a nurse in Israel - said she intended to contest "police treatment" on the night in question, but would not elaborate on her plans.

"I actually thought I was being pranked by paparazzi photographers."
