A Four Corners investigation has revealed labour exploitation, slave-like conditions and black market labour gangs on farms and in factories supplying Australia's biggest supermarkets and fast food chains. The report found that crime syndicates and labour hire contractors were exploiting Australia's 417 working holiday visa system, leading to foreign staff being abused, women being sexually harassed, and staff being paid low.

Companies' responses are provided in an article by the Sydney Morning Herald (linked below).
