Australia warned over labour-trafficking

In a hard-hitting assessment of global human trafficking, the US State Department found Australia complied with all minimum requirements but said work was needed on the 457 visa scheme.

The scheme allows businesses to import workers temporarily if they cannot fill skilled vacancies.

"The Australian government should devote more attention and resources to addressing allegations of labour-trafficking, including in connection with its 457 worker visa program," the State Department said.

A senate committee investigating the 457 visa program has heard of numerous cases of alleged exploitation of temporary workers.
