A Sydney magistrate has launched a blistering attack on alcohol-fuelled violence by women, telling one eastern suburbs woman that "it's about time sentences are imposed [on] females that are imposed on males for the same thing”.

Magistrate Michael Barko on Wednesday handed British national Elizabeth Hasler 250 hours of community service for attacking her Gai Waterhouse colleague in what he called a "drunken rage of jealousy".

According to the agreed police facts, Hasler and her co-workers were having drinks at The Doncaster Hotel in Kensington on March 3 after a race meeting at Royal Randwick racecourse.

Hasler and the victim, both stablehands, left the pub together just before midnight, when she shouted at the victim: "What the f--- are you looking at?” She claimed the victim had been looking at Hasler's fiance throughout the night.
