Wage theft and exploitation inflicted by farm managers forces migrant workers to go dumpster diving just to survive.

Kate Hsu, a Taiwanese foreign worker, said she was paid $4 an hour for picking oranges on a farm in South Australia, leaving her no choice but to eat from public rubbish bins just to survive.

Unions NSW secretary Mark Morey said the horrific treatment goes beyond underpayment, but leaves many overseas workers vulnerable as employees have the power to influence their visa status.

Migrant Workers Centre director Matt Kunkel said they “demand the federal government to undertake urgent measures to address this catastrophic situation.”
