Renee Prendergast, 45, was found guilty at a judge-alone trial in May of failing to provide her elderly mother Julie with the necessities of life over June 11 to 13, 2021.
She was cleared at trial of charges that she financially defrauded Julie and her father Josef, who both suffered long-term health problems.
In convicting Prendergast and handing her a conditional release order to be of good behaviour for two years, the judge took into account that she had been under "significant carer's stress".
He also considered the limited duration of the offending, being no more than three days.
Another factor, he said, was media coverage of the case on the issue of elder abuse, which had made Prendergast's life more difficult.
