Close contact rules vary state by state.   In South Australia, close contacts who are essential workers (including aged care workers) are exempt from isolation and may continue to work after a negative test result, if they are asymptomatic.   In Queensland, close contacts who are essential workers (including aged care workers) are exempt from isolation and may continue to work after a negative test result, if they are asymptomatic and fully vaccinated.   In Western Australia, close contacts must follow the directive of the WA Department of Health, which may include having to isolate and test. Currently, there is no general exemption to isolation for aged care workers.
