An ugg boot retailer will face court for allegedly paying an overseas worker in Sydney just $8 an hour.

The Chinese national, in her late 20s, was in Australia on a 417 working holiday visa when she was employed as a casual salesperson.

She was allegedly short changed more than $4200 over just two months in April and June last year.

The worker was allegedly paid only $8 an hour to staff pop up stores at shopping centres at Wetherill Park, Merrylands, Winston Hills, and Chester Hill in Sydney’s western suburbs.

She was entitled to more than $22 for normal hours, penalty rates up to $32 for weekend work and $43 an hour on public holidays.

The Fair Work Ombudsman has commenced legal action against Strathfield man, Yue Hua Liu, and a company in which he is the majority shareholder, Ever Australia Pty Ltd.

The company manufactures and sells ugg boots and other products under the ‘Ever UGG’ brand.

Fair Work Ombudsman, Natalie James, says Liu had previously been warned about paying unlawful, low flat rates of pay.

In 2013, Liu was required to back pay two other overseas workers more than $9000 after he had similarly paid them just $8 an hour.

Liu gave an undertaking at the time that he would pay minimum lawful entitlements in future.

He faces maximum penalties of up to $10,200 per contravention and Ever Australia faces maximum penalties of up to $51,000 per contravention.

The matter will be heard in the Federal Circuit Court in Sydney.

James says the underpayment of vulnerable overseas workers is a serious matter and she takes a dim view of employers who allegedly continue to flout the law after being educated about their workplace obligations.
