Santas in Australia's largest city have been told not to use Father Christmas's traditional "ho ho ho" greeting because it may be offensive to women

Sydney's Santa Clauses have instead been instructed to say "ha ha ha" instead, the Daily Telegraph reported.

One disgruntled Santa told the newspaper a recruitment firm warned him not to use "ho ho ho" because it could frighten children and was too close to "ho", a US slang term for prostitute.

"Gimme a break," said Julie Gale, who runs the campaign against sexualising children called Kids Free 2B Kids.
