Mining major Rio Tinto has relocated more than 700 of its staff with "specialist skills" to Perth from interstate as the Western Australian government put in place a hard border.
Premier Mark McGowan last week announced that while interstate fly-in, fly-out workers would be allowed into the state, they would be subjected to a strict 14-day self-isolation measure before being allowed onto Western Australian mine sites. Rio on Monday also noted that more than 1 200 of its employees at two of its Pilbara sites commenced new rosters that had been redesigned to reduce the risk of spreading the virus.
