In 2024–25:
- SHS agencies assisted around 24,600 clients (aged 10 and over) who had problematic drug and/or alcohol use, representing 8.5% of all SHS clients.
- Nearly 4 in 5 (79% or 19,400) clients with problematic drug and/or alcohol use needed assistance with accommodation provision, higher than any other SHS client group.
- The rate of clients with problematic drug and/or alcohol use has decreased from 11.8 clients for every 10,000 people in 2011–12 to 10.2 in 2024–25.
People experiencing problematic drug and/or alcohol use are especially vulnerable to experiencing housing instability or homelessness (Coombs et al. 2024). Problematic use can have wide-ranging effects on a person’s mental and physical health, income, employment, education, and other areas of life that may make it difficult to maintain stable housing or transition out of homelessness.
The relationship between problematic drug and/or alcohol use and homelessness is complex and can work in both directions. While substance use may increase the risk of housing instability, experiences of homelessness can also contribute to or exacerbate problematic use. For example, research from homelessness services in Melbourne found that 43% of people experiencing homelessness reported alcohol or other drug use problems, and two-thirds of these individuals developed these problems after becoming homeless (Johnson and Chamberlain 2008).
This chapter focuses on SHS clients who were seeking support for problematic drug and/or alcohol counselling, self-reported problematic drug and/or alcohol use, or were referred or provided services by a rehabilitation facility. The characteristics, service use patterns and housing outcomes of this cohort are presented below.

Reporting clients with problematic drug and/or alcohol use in the Specialist Homelessness Services Collection (SHSC)
SHS clients aged 10 and over are considered to have problematic drug and/or alcohol use if, at the beginning of or during support, the client provided any of the following information:
- recorded their dwelling type as rehabilitation facility
- required drug and/or alcohol counselling
- were formally referred to the SHS agency from an alcohol and drug treatment service
- had been in a rehabilitation facility or institution during the past 12 months
- reported problematic drug, substance or alcohol use as a reason for seeking assistance or the main reason for seeking assistance.
The identification of clients with problematic drug and/or alcohol use may be current or recent; referring to issues at presentation, just prior to receiving support or at least once in the 12 months prior to support.
For more information see Technical notes.
Client characteristics
Clients with problematic drug and/or alcohol use were most likely to be aged 35–44 years (26%) and have received assistance from SHS agencies in the past (79%).

Presenting unit and Living arrangements
Most clients (90% or 22,000) with problematic drug and/or alcohol use presented to SHS agencies for assistance alone, higher than for all SHS clients (63%). A further 6.7% (or around 1,600) of clients were single with one or more children, lower than for all SHS clients (29%) (Supplementary tables CLIENTS.9 and CLIENTS.44).
The living arrangements reported by SHS clients with problematic drug and/or alcohol use at the beginning of support were different from the overall SHS population and other client groups. In 2024–25 (Supplementary tables CLIENTS.10 and CLIENTS.45):
- About 63% (or around 15,200) of clients with problematic drug and/or alcohol use were living alone at the beginning of SHS support, higher than the proportion for all SHS clients (34%)
- Fewer clients with problematic drug and/or alcohol use were living as one parent with child(ren) (11% or 2,600 compared with 34% of all SHS clients).
Client needs and main reason for assistance
Nearly 4 in 5 (79% or 19,400) clients with problematic drug and/or alcohol use needed assistance with accommodation provision, higher than any other SHS client group.
Main reasons for seeking assistance
Few SHS clients (4.7%) with problematic drug and/or alcohol use reported problematic drug or substance use issues as the main reason for seeking SHS assistance (Supplementary table SUB.5). More than 1 in 6 (18%) clients identified housing crisis as the main reason for seeking SHS services, and 1 in 7 (15%) identified inadequate or inappropriate dwelling conditions.
The most common main reasons for seeking assistance among clients with problematic drug and/or alcohol use who were experiencing homelessness at the start of support were (Supplementary table SUB.6):
- inadequate or inappropriate dwelling conditions (21% or 3,000)
- housing crisis (19% or 2,900 clients)
- family and domestic violence (10% or 1,500).
For those at risk of homelessness the main reasons for seeking assistance were (Supplementary table SUB.6):
- family and domestic violence (18% or 1,600 clients)
- housing crisis (16% or 1,400)
- transition from custodial arrangements (10% or 900).
Service use patterns
In 2024–25, clients received a median of 108 days of support, down from 119 days in 2021–22, an average of 2.7 support periods per client, and a median of 41 nights of accommodation (Supplementary table CLIENTS.48).
Services needed and provided
Services provided to clients range from the direct provision of accommodation, such as a bed in a shelter, to more specialised services such as counselling and legal support. These services are either provided to the client directly by the agency or the client is referred to another SHS agency or specialised service.
In 2024–25, clients with problematic drug and/or alcohol use were more likely than all SHS clients to need certain services (Figure SUB.2, Supplementary tables SUB.2 and CLIENTS.24), including:
- drug/alcohol counselling (31%, compared with 2.8% of all SHS clients)
- short-term housing (63%, compared with 40%)
- medium-term housing (50%, compared with 30%)
- mental health services (27%, compared with 7.7%)
- living skills/personal development (34%, compared with 15%)

Housing situation and outcomes
SHS clients with problematic drug and/or alcohol use had a high proportion of clients who were rough sleeping, higher than most other SHS client groups.
This section highlights changes in clients’ housing situation between the start and end of support. That is, the place they were living before and after receiving assistance from a SHS agency. The data includes only clients who ceased receiving SHS support during the financial year and were no longer receiving ongoing support from a SHS agency.
Specifically, it compares clients’ housing at the start of their first support period in 2024–25 with the end of their last support period in 2024–25. It does not capture changes that occurred during a support period, nor changes throughout the year between different support periods.
While housing outcomes for SHS clients generally trend toward more stable housing, clients with problematic drug and/or alcohol use were more likely than other SHS client groups to experience homelessness –particularly rough sleeping– both at the start and end of SHS support. Around 1,500 clients who began support rough sleeping remained in this situation at the end of support (Supplementary table SUB.3).
In 2024–25, SHS clients with problematic drug and/or alcohol use were more likely than other clients to be rough sleeping at the start of support (24% compared with 13% of all clients) and at the end of support (16% compared with 8.5% of all clients) (Supplementary tables SUB.3 and CLIENTS.31).
In 2024–25, of the 8,900 clients with problematic drug and/or alcohol use who were known to be experiencing homelessness at the start of support (Figure SUB.3 and Supplementary table SUB.3):
- around 5,500 clients were homeless when support ended
- around 2,000 clients were in short-term accommodation, and 1,900 clients were rough sleeping when support ended.
In 2024–25, of the 5,700 clients who were known to be at risk of homelessness at the start of support:
- many clients maintained their housing situation when support ended; around 1,400 clients maintained public/community housing and around 1,300 clients maintained private housing.
- 1 in 5 clients (21%) were experiencing homelessness when support ended, a greater proportion than any other client group.

Sankey diagram shows the most common housing situation at the start of support was no shelter or improvised/inadequate dwelling and at the end of support was public or community housing.
