The Fair Work Ombudsman said the franchisee of the Sushi Izu bars inside Woolworths' Town Hall and Double Bay supermarkets had paid the man - who was on a working holiday - less than $16.50 an hour when he was entitled to $17.98 during normal hours and up to $39.57 on penalty rates. The 26-year-old South Korean backpacker, on a 417 working holiday visa, worked at Sushi Izu for three months, preparing food and cleaning.
