Westhaven chief executive officer Andrew Everett said when coronavirus began spreading in Australia, it took steps to protect clients and staff.
"Since the beginning of the COVID-19 crisis in Australia we ceased all non-essential services including community and day programs and our Westhaven Business Services," he said.
"Westhaven has introduced social distancing, provided additional infection-control training to all staff, increased hand-cleaning stations and restricted access from external parties to our properties.
"In addition, we have recently closed our head office with corporate staff working from home."
