Mental illness is often treated in community and hospital-based outpatient care services provided by state and territory governments. Collectively, these services are referred to as community mental health care (CMHC) services.
State and territory health authorities collect a core set of information for the Community Mental Health Care National Minimum Data Set (CMHC NMDS), which is compiled annually into the National Community Mental Health Care Database (NCMHCD). Data from the NCMHCD are used to describe the care provided by these services. More information about the NCMHCD is available in the data source section.
Infographic containing a map of Australia showing community mental health services by location, principal diagnosis, estimated number of patients in community mental health care in Australia and involuntary contacts for the years 2005–06 to 2020–21.
Around 10.2 million service contacts were provided by community mental health care services to nearly 481,500 patients in 2020–21. This equates to an average of about 21 per patient.
The national average rate of patients receiving services was 19 patients per 1,000 population. The rate was highest in the Northern Territory (31) (Figure CMHC.2). Differences in jurisdictional data reporting systems may contribute to the observed variation in rates.
Interactive vertical bar chart showing the number of community mental health care patients, service contacts and treatment days as well as the rate of contacts and patients (rate per 1,000 population) for states and territories in 2020–21. New South Wales had the highest number of patients (146,498), followed by Queensland (113,493), Victoria (80,500), Western Australia (67,654), South Australia (43,860), the Australian Capital Territory (11,579), Tasmania (10,158) and the Northern Territory (7,711). The Northern Territory reported the highest rate (31 patients per 1,000 population) followed by the Australian Capital Territory (27), Western Australia (25), South Australia (25), Queensland (22), Tasmania (19), New South Wales (18), and Victoria (12). The national rate of community mental health care patients was 19 per 1,000 population (refer to Table CMHC.1).
Note: Community mental health care treatment days is only reported as a number.

In 2005–06, almost 5.7 million CMHC service contacts took place across Australia. This has increased to around 10.2 million in 2020–21.
Across Australia in 2020–21 the rate of service contacts was 399 per 1,000 population and the rate of patients was 19. The national rate of both service contacts and patients per 1,000 population has increased between 2016–17 and 2020–21 (365 to 399 for contacts and 17 to 19 for patients). In this 5-year period, the average annual change for the rate of service contacts shows an increase of about 2%. The rate of community patients showed an average annual increase of the same proportion. The annual change over this time period varied across jurisdictions.
Victoria showed the largest increase in the rate of service contacts between 2016–17 and 2020–21 (from 253 to 343) and the Australian Capital Territory had the highest rate of service contacts in 2020–21 (849).
Nearly 2 in 5 registered patients (39%) had a length of treatment of 92 days or more (the time between their first and last service contact during the reporting period) in 2020–21.
These patients received the highest proportion of treatment days (81%) from CMHC services (Figure CMHC.3).
Stacked vertical bar chart showing length of treatment period and the proportion of patients that received different lengths of treatment. 37% of patients received very brief treatment (1–14 days), 24% received short term treatment (15–91 days) and 39% received medium to longer term treatment (92+ days). 6% reported treatment days were very brief, 13% were short term treatment and 81% were medium to longer term treatment (refer to table CMHC.25).
In 2020–21, a slightly higher proportion of CMHC patients were females (53%). However, males accessed services at a similar rate to females (394 and 393 per 1,000 population respectively). People aged 12–17 years accounted for the highest rate of both patients (39) and service contacts (751), with females accounting for a higher rate of service contacts than males: 1,063 and 447 respectively.
People living in Major cities made up the majority of CMHC patients (64%) and people living in Very remote areas made up the smallest proportion (2%). However, the population adjusted rate of patients was highest for people living in Very remote areas (38 per 1,000 population) and people living in Major cities has the lowest rate (16).
Aboriginal and Torres Strait Islander patients comprised 11% of CMHC patients in 2020–21, however the rate per 1,000 population was more than 3 times that of non‑Indigenous patients (60 and 17 respectively) (Figure CMHC.4).
Two interactive charts. A horizontal bar chart showing the rate (per 1,000 population), per cent or number of community mental health care patients by demographic variables of age, sex, Indigenous status, remoteness area and SEIFA quintile in 2020–21. The lowest rate for patients by age was seen for those aged 0–4 years (2 people per 1,000 age specific population) and the highest rate was for patients aged 12–17 years (39). Male and female patients had similar rates per 1,000 population (18 and 20 respectively). The highest rate of patients per 1,000 population by remoteness area was seen for patients living in Very remote areas (38), followed by Remote (33), Outer regional (26), Inner regional (22), and lowest for Major cities (16). The rate of patients per 1,000 population living in SEIFA Quintile 1 (most disadvantaged) was the highest of all quintiles (23), which decreased to 13 for Quintile 5 (least disadvantaged) (refer to Table CMHC.9). The 2nd figure is a time series of community service contacts by patient demographics from 2005–06 to 2020–21 (refer to Table CMHC.8).
Note: Age-standardised rate is shown for Indigenous Status.
In 2020–21, Mental disorder not otherwise specified was the most frequently recorded mental health-related principal diagnosis for CMHC contacts (25%). For those patients with a known diagnoses Schizophrenia (21%) was the most common followed by:
A principal diagnosis was reported for 4 out of 5 (almost 8.5 million) CMHC service contacts.
There is variation however across age groups when looking at the most frequently recorded principal diagnosis for service contacts (Figure CMHC.5). Younger age groups (those aged up to 34 years) and older age groups (those aged 65 years and over) most frequently recorded Mental disorder not otherwise specified, while those aged 35–64 years most frequently recorded Schizophrenia.
Interactive horizontal bar chart showing 6 commonly reported specific principal diagnosis for community mental health care service contacts in 2020–21 by age group. The most frequently reported principal diagnosis for those aged 0–4 years, 5–11 years, 12–17 years, 18–24 years, 25–34 years, 65–74 years, 75–84 years and 85 years and over was Mental disorder not otherwise specified (25%, 28%, 26%, 27%, 26%, 21%, 21% and 24% respectively). For older ages, Schizophrenia was the most frequently reported principal diagnosis, ranging from 30% for those aged 55–64 years to 33% for those aged 35–44 years (refer to Table CMHC.18).
CMHC service contacts can be conducted as either individual or group sessions. Service contacts can also be face-to-face, via telephone, or using other forms of direct communication such as video link. They can be conducted in the presence of the patient, with a third party (such as a carer or family member) and/or other professional or mental health worker.
The majority of service contacts reported in 2020–21 involved individual contact sessions (96%) and 4% of contacts were group sessions. Just over half of all contacts were individual sessions (52%), where the patient participated in the service contact (termed patient present).
Services targeted toward the General population made up 69% of all. Services targeted towards Forensic, Older person, and Youth populations accounted for much smaller proportions of treatment days than the General population and Child and adolescent services. These results largely mirror the relative size (as measured by the number of full-time-equivalent staff) for each of the CMHC service target population categories, with the exception of Older person and Child and adolescent which both make up 11% (Specialised mental health care facilities section, Table FAC.41).
The duration of CMHC service contacts ranges from less than 5 minutes to over 3 hours. In 2020–21, the average service contact duration of sessions was 34 minutes. Nearly 2 in 5 contacts were 5–15 minutes (38%) and almost 1 in 4 contacts were 16–30 minutes (24%) (Figure CMHC.6). Service contacts with the patient present were on average twice as long in duration than service contacts where the patient was absent (average 45 and 22 minutes respectively).
Of the 5 commonly reported principal diagnoses, Reaction to severe stress and adjustment disorders had the highest proportion of contacts lasting over 1 hour (13%, Table CMHC.23).
Two interactive charts. A stacked horizontal bar chart showing the duration of community mental health care service contacts by session duration and patient participation status in 2020–21. The most frequent contact duration was 5–15 minutes (38%), followed by 16–30 minutes (24%), >0.5–1 hour (20%), >1–3 hours (11%), <5 minutes (6%), and >3 hours (1%). 53% of contacts occurred with the patient present (5.4 million) and 47% occurred with the patient absent (4.8 million). Contacts lasting more than 3 hours were more likely to occur with the patient present than without the patient (1% and 0.2% respectively), while contacts lasting less than 5 minutes were more likely to occur without the patient than with the patient (11% and 0.6% respectively) (refer to Table CMHC.22). 2ND figure is a time series of service contacts by session duration from 2005–06 to 2020–21 (refer to Table CMHC.24).
Figure CMHC 6.1, time series of service contacts by session duration can be found on the Mental health site.
More than 1 in 7 (15%) CMHC service contacts in 2020–21 involved a patient with an involuntary mental health legal status. Western Australia reported the lowest proportion of involuntary contacts (3%), while Queensland reported the highest (25%). These differences most likely reflect the different legislative arrangements in place amongst the jurisdictions. More information can be found in the CMHC NMDS Data Quality Statement.
In 2020–21, of the 5 commonly reported principal diagnoses, the highest proportion of contacts involving a patient with an involuntary mental health legal status was seen for patients diagnosed with Schizoaffective disorders (43% involuntary) (Figure CMHC.7).
Two interactive charts. A horizontal bar chart comparing the number and proportion of voluntary and involuntary contacts for 5 of the most commonly reported principal diagnoses in 2020–21. Schizoaffective disorders (57% voluntary and 43% involuntary); Schizophrenia (63% voluntary and 37% involuntary); Bipolar affective disorders (77% voluntary and 23% involuntary); Reaction to severe stress and adjustment disorders (97% voluntary and 3% involuntary); Depressive episode (97% voluntary and 3% involuntary) (refer to Table CMHC.28). 2ND figure is a time series stacked vertical bar chart showing community mental health care service contacts by mental health legal status and by state and territory (refer to Table CMHC.27).

State and territory health authorities collect a core set of information for the Community Mental Health Care National Minimum Data Set (CMHC NMDS), which is compiled annually into the National Community Mental Health Care Database (NCMHCD). The statistical counting unit used in the NCMHCD is a service contact between either a patient or a third party and a specialised community mental health care (CMHC) service provider.
Differences in jurisdictional data reporting systems, reduced data coverage or under-reporting of service contacts may contribute to variation in service contact rates. Staff industrial action has resulted in a substantial reduction in data coverage for 2 jurisdictions in some years: Victoria (2011–12, 2012–13, 2015–16 and 2016–17) and Tasmania (2011–12, 2012–13 and 2018–19). New South Wales and the Northern Territory also reported reduced data coverage for 2016–17, 2017–18 and 2018–19. The observed reductions in both service contact and patient numbers are considered to be primarily due to these missing data. Consequently, long term trends in the total number of service contacts are not available. Further information on data coverage can be found in the CMHC NMDS Data Quality Statement.
Data Quality Statements for National Minimum Data Sets (NMDSs) are published annually in AIHW’s Metadata Online Registry (METeOR). These statements provide information on the environment, timelines, accessibility, interpretability, relevance, accuracy and coherence of the Institution. Visit the Community mental health care NMDS 2019–20: National Community Care Database, 2021 Quality Statement. Data quality statements for previous years are also accessible in METeOR.
The footnotes in each of the accompanying MS Excel tables contain details about the calculation of national rates over time.
The number of unique patients provided with service contacts can be derived from the NCMHCD. However, the patient count is limited to people registered with state and territory community mental health care systems that have a unique person identifier; a person has one identifier across all individual service providers within a state or territory. The ability of jurisdictions to generate unique person identifiers varies as described in the data quality statement for the CMHC NMDS.
Some specialised mental health services data are categorised using 5 target population groups (see METeOR identifier 682403):
Note that in some states specialised mental health care beds for aged persons are jointly funded by the Australian federal and state and territory governments. However, not all states or territories report such jointly funded beds through the National Mental Health Establishments Database.
Treatment day refers to any day on which one or more service contacts (direct or indirect) are recorded for a registered patient (identified by a patient identifier number assigned to a uniquely identified person) during an ambulatory care episode.
The number of treatment days are grouped as follows in Table CMHC.25: 1–14 days, 15–91 days and 92+ days.
Data coverage includes the time period 2005–06 to 2020–21. Data in this section was last updated in October 2022.
