Of the 23,400 SHS clients who reported problematic alcohol and/or drug use in 2021–22:
- Over 3 in 4 (76.1%) clients were aged under 45 years (AIHW 2022, Table SUB.1).
- Of those who needed accommodation (18,900), almost two-thirds (62.5%) were provided accommodation while a further 13.9% were referred to another agency (AIHW 2022, Table SUB.2).
- Around 1 in 6 (16.8%) clients were sleeping rough (no shelter or improvised/inadequate dwelling) when they sought services and over 1 in 10 (11.0%) exited services sleeping rough (AIHW 2022, Table SUB.3).
- Around 1,100 (4.8%) clients were formally referred to a SHS agency by an alcohol and drug service (AIHW 2022, Table SUB.7).
- 43.2% had a current mental health issue, 8.0% had experienced family and domestic violence and 31.9% experienced both vulnerabilities (AIHW 2022, Table CLIENTS.45).
Tobacco smoking
The general health status of the people experiencing homelessness tends to be poorer than the general population.
- In the absence of national smoking rates for people experiencing homelessness, a study in Melbourne from 1995–96 found that 77% of people who were experiencing homelessness were smokers and this increased to 93% for those people experiencing homelessness who were sleeping rough (living on the streets) (Kermode et al. 1998).
- Studies have shown that people experiencing homelessness may adapt their smoking behaviours in order to save money, thus exposing themselves to greater health risks. This can include sharing cigarettes and smoking from used cigarette butts or filters (Okuyemi et al. 2006).
- The Journeys Home data showed that an average increase in consumption of one cigarette a day increased the risk of experiencing homelessness by 0.2% (Johnson et al. 2015).
Alcohol consumption
Research has found that problematic alcohol consumption is associated with homelessness.
- The Journeys Home data showed that an average increase in alcohol consumption of one drink a day, increased the risk of experiencing homelessness by 0.2% (Johnson et al. 2015).
- Around 2.6% (7,100) of SHS clients reported that they had sought assistance for problematic alcohol use in 2021–22, a similar proportion to previous years (AIHW 2022).
- Among those who received specialist alcohol and other drug treatment services, alcohol was the principal drug of concern (40.4%) for people who sought support from both SHS and alcohol and other drug (AOD) treatment services. This was slightly higher than those who had not sought assistance for homelessness (AIHW 2016, Table S1.1).
Illicit drugs
Regular drug use is correlated with entries into homelessness (Johnson et al. 2015). In 2021–22, around 5.3% of clients (14,300) who sought assistance from SHS reported problematic drug or substance use (AIHW 2022).
The Illicit Drug Reporting System (IDRS) is an annual survey of people across Australia who regularly inject illicit drugs (Sutherland et al. 2022). Of the 879 participants interviewed in 2022, one-quarter (26%) reported that they were homeless (that is, current accommodation was no fixed address, shelter/refuge or boarding house/hostel). This is stable when compared to 2021 (27%).
In 2022, Brisbane (32%), Melbourne (29%), and Perth (27%) had the highest proportion of respondents reporting homelessness. While Sydney (23%) Canberra (18%), Hobart (19%) and Adelaide (25%) had lower percentages. In Darwin, 81% of respondents reported owning a home (includes renting); other responses were not recorded (Sutherland et al. 2022, Table 1).
IDRS data collection for 2022 took place from May to July. Due to COVID-19 restrictions being imposed in various jurisdictions during data collection periods, interviews in 2020, 2021 and 2022 were delivered face-to-face as well as via telephone. This change in methodology should be considered when comparing data from the 2020, 2021 and 2022 samples relative to previous years.
Health and harms
For clients with problematic alcohol and/or other drug use, additional vulnerabilities such as mental health issues, may make them more vulnerable to homelessness. In 2019–20, 44% (or more than 12,400) clients with problematic drug and/or alcohol use also reported a current mental health issue and 31% (almost 8,700) reported a current mental health issue and experiencing family and domestic violence (AIHW 2020). For clients with problematic alcohol and/or other drug use, additional vulnerabilities such as mental health issues, may make them more vulnerable to homelessness. In 2019–20, 44% (or more than 12,400) clients with problematic drug and/or alcohol use also reported a current mental health issue and 31% (almost 8,700) reported a current mental health issue and experiencing family and domestic violence (AIHW 2020).
Treatment
Research has shown that there is often overlap between drug and alcohol misuse and homelessness (AIHW 2016). The Alcohol and Other Drug Treatment Services National Minimum Data Set (AODTS NMDS) collects information on treatment provided to clients by publicly funded alcohol and other drug treatment services, yet it does not collect information on the client’s experience of homelessness.
To better understand the characteristics of those experiencing homelessness and alcohol and other drug issues, a recent study linked the AODTS NMDS to the SHS data collection (AIHW 2016). The key findings demonstrate that the homeless population experiences additional complexities. Specifically, clients who had sought assistance from both SHS and AODTS:
- had lower rates of unemployment (6%), compared to 13% of SHS-only clients
- comprised a higher proportion of Indigenous Australians (27%) compared to 13% of AODTS only clients
- sought treatment for multiple drugs (18%), 3 times higher than the AODTS only population
- had poor AOD treatment and housing outcomes compare to the AODTS-only and SHS-only populations.
Of those who had sought assistance for both homelessness and AOD treatment, the most common principal illicit drugs of concern (the main substance that the client sought treatment for) were cannabis (28.6%) and amphetamines (20.5%) (Figure HOME1).
Persons who sought assistance from both SHS and AODTS were twice as likely to report heroin as a principal drug of concern (11.3%) compared to 5.7% for AODTS only (AIHW 2016, Table S1.1).
