Adult Mental Health ​Inpatient units

There are two adult Mental Health Inpatient units located at Hornsby Ku-ring-gai Hospital for people aged 18 and over who are experiencing mental illness requiring inpatient support – the Adult Inpatient Unit and the Mental Health Intensive Care Inpatient Unit (MHICU)(State Service).

People access these services via presentation at the Emergency Department or via the Local Community Mental Health Service (Adult Inpatient Unit) or, for the MHICU via Adult Inpatient Mental Health Units.

Adolescent Inpatient Unit (Brolga) Brolga Unit​

The Adolescent Inpatient Unit (Brolga) Brolga Unit located at Hornsby Hospital is for young people aged between 12 and 17 years of age who are experiencing a serious episode of mental illness requiring inpatient support. ​

People access this service via presentation at the Emergency Department or via referral from Specialist Community Child and Youth Mental Health Service (CYMHS) teams.

Urgent care: If life is at risk please call Triple Zero (000) or go to the emergency department of your local hospital to receive immediate help.


For people seeking urgent mental health care there are several options:

Ring the Mental Health Line on 1800 011 511. This line is staffed by experienced clinicians 24 hours a day, 7 days a week. This is a telephone-based triage service. Calls are answered 24 hours, 7 days a week, by a mental health clinician who can offer support and connect you with the appropriate local, public mental health service in NSW, including the Northern Sydney Local Health District.


The service may then offer you an appointment at the community health centre, or a clinician may come to your home to complete an assessment and plan treatment with you.


Attend the Emergency Department at Hornsby Ku-ring-gai Hospital, where there is 24 hour access to specialist mental health care and support.

Visitor Information

Visitors are welcome in our mental health units. Friends and family are important in supporting recovery.  It is always a good idea to phone the unit in advance of your visit to ensure it will be a good time for you to come as there are some times when the units are not open to visitors, such as during treatment times.  To speak to staff in the Mental Health Unit, you can call the general phone number of the hospital and ask to be put through to the mental health unit.


Certain things aren't allowed in the unit, in order to help keep everyone safe. These things are referred to as contraband, and include things like cigarette lighters and weapons. You should check with the unit to find out about contraband. Visitor's belongings may be searched prior to entry to the unit. You won't be able to take things like handbags, backpacks or mobile phones into the unit; we will provide a secure space where you can store these. Children are welcome to visit friends and relatives in the mental health unit. All units have a procedure and specific space allocated to support visits from children. It is very important to phone the mental health unit before bringing a child to visit someone in the unit, to ensure things are in place to support a positive and stress free visit.


All wards in NSW Health facilities are smoke free. Smokers will be supported in their drug withdrawal with appropriate clinical care and the provision of free nicotine replacement therapy during their stay.
