Illegal workers arrested in SA

Nine illegal workers have been arrested in a raid on a farm in the Adelaide Hills.

The Immigration Minister, Chris Evans, says a Chinese national, three Malaysians and five Cambodians were caught working at the Mount Barker property.

Four are unlawful non-citizens and five had their visas cancelled because they were not supposed to work in Australia.

Six of them will be deported and two have agreed to leave voluntarily.

A decision has not been made on the fate of the other detainee.
