Maroochy Sunshine was contractually obliged to provide 22 workers from Vanuatu, who were in Australia as part of the Seasonal Worker Program, $500 a week for at least 30 hours' work.
The company allegedly arranged sporadic work in the Lockyer Valley, Sunshine Coast and Bundaberg areas in July 2014.
Thirteen workers were paid nothing for their work, the Fair Work Ombudsman claimed. Other workers were allegedly paid amounts between $50 and $300, were underpaid on their leave entitlements and received their pay infrequently.
