Federal legal proceedings have begun against Dai II Kang, the owner of a Sushi Kuni outlet at Redcliffe and former owner of a Sushi Kuni outlet in New South Wales, along with his company EJ Group International Pty Ltd, over allegations five employees at the two outlets were underpaid $28,615.

FWO officers allegedly discovered two Korean workers on student and 417 working holiday visas and an Australian employee at the Ballina outlet were allegedly paid flat rates of $120-$160 a day and had been underpaid $19,308 over eight months in 2015.

Two other Korean nationals at the Redcliffe outlet had also allegedly been paid flat rates and underpaid $10,312 over four month across 2015 and 2016, according to FWO officers.

The flat rates allegedly resulted in underpayment of minimum hourly rates, weekend penalty rates, overtime and casual loadings they were entitled to.

FWO has also alleged Mr Kang and his company knowingly handed over false time-and-wages records to officers.

Mr Kang faces maximum penalties of up to $10,800 per contravention and EJ Group International Pty Ltd faces penalties of up to $54,000 per contravention.

These latest allegations come after more than $340,000 penalties were handed out to the operators of a number of Japanese-style food outlets across Queensland since January this year.
