As for the existing 457 visa scheme, the employers will now have to declare that they could not find an Australian for a particular job before hiring any foreign worker.
Under the new rule, companies will have to advertise for four months in a newspaper for a position before sponsoring a foreigner, Sydney Morning Herald reported.
