The Optus outage caused widespread disruption to regional hospitals and health clinics.
In a social media post, Ramsey Health Care says its phone services have been disrupted by the Optus network outage.
The private provider serves 73 hospitals across the country, including Shepparton Private Hospital and Albury-Wodonga Private Hospital.
Ramsay Health Care recommends that anyone who needs to contact one of its hospitals use the contact form on the local hospital website.
In Victoria, South West Healthcare is unable to respond to external calls from the public due to the outage.
A spokesperson said the organisation’s facilities, which include Warrnambool Base Hospital, were temporarily diverting main switchboards to Telstra mobile numbers.
Members of the public are asked to call the number that concerns them and keep the call briefso that phone lines can remain open to everyone who needs to access the service.
