Lack of sleep reduces FIFO workers' alertness by 20 per cent on mine sites, study finds

Western Australia's fly-in fly-out (FIFO) workers are not getting enough rest, according to scientists behind the world's largest study of its kind.

Edith Cowan University researchers tracked the sleep of 88 FIFO workers and found most were "barely scraping" the threshold for adequate rest on days off, let alone days on shift.
