Investigations still ongoing

Operation Polo spokesman Samuel Dinnison said police were also still assessing items that were taken in subsequent searches of local market gardens for suspected illegal workers.

He said police were working with the Department of Immigration to determine where the detained workers came from and ‘what they have been up to in Australia’.

‘We were expecting many of them to be visa overstayers, and will now work with Immigration officials to determine how they entered the job market,’ he said.

‘We are interviewing them to find out where they were working and in what industries.’
