What is AOD? (alcohol and other drugs)

AOD stands for “alcohol and other drugs”. It’s the term used across Australia’s health, government, and community services sectors to name a field of work and a policy area. You’ll see it in job titles, service names, and qualification titles.

If you’ve come across the term in a job ad, a course listing, or a news article, this guide explains how the sector uses it and what a career in the space looks like.

Where you’ll see “AOD” used

AOD shows up in a few consistent places.

Job titles and job ads. Roles like AOD worker, AOD support worker, and AOD counsellor appear across community health services, hospitals, and non-government organisations. Job ads often use the abbreviation without spelling it out.

Service names. Many health services run a dedicated “AOD program” or “AOD team” alongside mental health and family services. State and territory health departments also fund AOD services directly, which is one reason the abbreviation runs through Australian health policy.

Qualification titles. Vocational education uses AOD in course names too. Hader Institute of Education (RTO 45162) delivers the nationally recognised CHC43215 Certificate IV in Alcohol and Other Drugs and CHC53215 Diploma of Alcohol and Other Drugs, both built for people who want to work in this part of the community services sector.

Government policy. AOD appears in Australia’s National Drug Strategy documents and in state and territory health publications as shorthand for this policy area.

The AOD sector in Australia, in brief

The AOD sector covers work at both ends: preventing problems before they start and supporting people who are already affected by their own or someone else’s alcohol or drug use.

Broadly, AOD services fall into a few categories:

• Prevention and education: school programs, community education, and public health campaigns aimed at reducing AOD-related harm before it happens.
• Early intervention: brief support for people showing early signs of risky alcohol or drug use, often delivered through community health centres or outreach programs.
• Treatment and counselling: structured, ongoing support for people who want to change their relationship with alcohol or other drugs, delivered by counsellors, caseworkers, and clinical staff.
• Harm reduction: services focused on reducing the health and social harms of drug use, rather than requiring someone to stop using before they can access support.
• Family and community support: services for the families, friends, and communities affected by someone else’s alcohol or drug use.

AOD services and AOD-qualified workers operate across Australia, in metro, regional, and remote areas. For scale: 1,316 publicly funded AOD treatment agencies operated across the country in 2024–25, and non-government organisations delivered 72% of all treatment episodes (AIHW, Alcohol and other drug treatment services in Australia 2024–25).

AOD terminology: a short glossary

A handful of terms come up once you start reading about the AOD sector. Here’s what they mean, in plain language.

Harm minimisation. This is Australia’s official national policy approach to alcohol and drug issues. It rests on three pillars: demand reduction, supply reduction, and harm reduction. Harm reduction is one of those three pillars. We cover the framework in full in what is harm minimisation?.

Dual diagnosis. This describes a person experiencing a mental health condition alongside alcohol or other drug use at the same time. It affects the support a person needs and how AOD and mental health services work together. Our guide on what is dual diagnosis? goes into more depth.

Person-first language. This is language that puts the person before the condition or behaviour, such as “a person who uses alcohol and other drugs” rather than a label like “addict” or “substance abuser”. The AOD sector uses person-first language deliberately: it keeps alcohol and drug use in proportion to the rest of someone’s life, and it reduces the stigma that stops people from seeking support.

AOD worker. A general term for anyone whose job is to support people affected by alcohol and drug issues, through casework, counselling, outreach, or community programs. Job titles vary, but “AOD worker” is the umbrella term you’ll see used across job boards and service directories.

If a topic in this glossary touches you personally, the National Alcohol and Other Drug Hotline (1800 250 015) offers free, confidential information and referral, available across Australia.

Careers in AOD

For many people, “AOD” first shows up as a career question: what does someone in this field do, and how do you get started?

At a day-to-day level, AOD work covers casework, outreach, group facilitation, and support planning with people affected by alcohol or drug use. We’ve written a full breakdown in what does an AOD worker do?.

Frequently asked questions

What does AOD stand for?

AOD stands for “alcohol and other drugs”. It’s a term used across Australia’s health, community services, and government sectors to describe issues, services, and workforce roles connected to alcohol and drug use. You’ll see it in job titles, service names, and course titles, almost always as the standalone abbreviation rather than spelled out in full.

What is AOD in Australia?

In Australia, AOD is the standard shorthand used in health policy, community services, and vocational training for anything relating to alcohol and other drug use. It covers prevention, education, treatment, counselling, and harm reduction, delivered by government, non-government, and private services across the country.

What is an AOD worker?

An AOD worker supports people affected by their own or someone else’s alcohol or drug use, through casework, outreach, group programs, or counselling. The role sits within the broader community services and health sector, and many AOD workers hold a nationally recognised qualification such as the CHC43215 Certificate IV in Alcohol and Other Drugs or the CHC53215 Diploma of Alcohol and Other Drugs.

What is an AOD career?

An AOD career is any role focused on supporting people affected by alcohol and drug issues, including frontline support work and specialist counselling. Common entry points include the CHC43215 Certificate IV in Alcohol and Other Drugs, with further study options like the CHC53215 Diploma of Alcohol and Other Drugs for learners who want to build on their skills.

Is AOD the same as substance abuse?

No. “AOD” is a neutral, sector-wide term describing the policy area and workforce, while “substance abuse” is an outdated, stigmatising label the sector has moved away from. Current practice uses person-first language, such as “a person who uses alcohol and other drugs”, to describe individuals respectfully rather than reducing them to a behaviour or condition.

How do I start a career in AOD?

Start with a nationally recognised qualification, such as the CHC43215 Certificate IV in Alcohol and Other Drugs, which is designed as an entry point into frontline AOD roles. From there, many learners progress to the CHC53215 Diploma of Alcohol and Other Drugs to build toward more advanced or specialist positions in the sector.
