More than 90 per cent of Australians are not getting enough sleep, according to the largest ever national sleep census.
A recent survey conducted by Queensland's CQUniversity found that just four per cent of the 13,089 respondents woke up feeling refreshed on a daily basis.
While sleep disturbances affected almost one in four Australians, there was a significant difference in the amount of sleep required to function effectively at work - management executives in particular felt they needed less shut-eye than other office workers, students or stay-at-home parents.
