Inpatient, outpatient, detox — which one suits?

How to choose your treatment format

The right format isn't the most expensive one or the most marketed one — it's the one that fits the severity of dependence, the stability of your home environment, and the practical realities of work, family, and finances. There's no single right answer, but the framework below covers most situations.

Start with detox if withdrawal is medically risky

Severe daily alcohol use, daily opioid use (heroin, oxycodone, fentanyl), and long-term high-dose benzodiazepine use all involve withdrawal that can be medically dangerous and shouldn't be attempted without supervision. Severe alcohol withdrawal can cause seizures and delirium tremens. Benzodiazepine withdrawal can cause seizures and prolonged neurological symptoms. Opioid withdrawal isn't usually life-threatening but is intensely uncomfortable and produces high relapse risk if unmedicated. For these substances the safest first step is a 5–10 day medically supervised detox in a hospital, dedicated detox unit, or supervised home-detox program — followed by rehab, not instead of it.

Choose residential rehab when home is unsafe or unstable

Residential (inpatient) rehab — staying onsite at a facility for 28 days to several months — is the right choice when home life is destabilising recovery, when previous outpatient attempts haven't held, when there's significant co-occurring mental health concern, or when the person needs a complete break from current routines to reset. Programs of 60 and 90 days consistently show better long-term outcomes than 28-day programs in the research, particularly for severe dependence. The trade-off is time away from work and family — 28 days minimum, often more — and cost in the private sector.

Choose outpatient when home is stable

Outpatient programs — living at home, attending sessions 2 to 5 times per week — are the most common form of AOD treatment in Australia, not because they're a "lite" version, but because for many people they're the more clinically appropriate format. Outpatient suits people whose home environment is reasonably stable, who can keep working, who want to integrate recovery skills into normal life from day one, or whose dependence is at a level where the structure of residential isn't necessary. The core therapeutic content — CBT, group therapy, relapse-prevention skills — is the same as residential. The wraparound is what differs.

Don't underweight aftercare

The single most consistent finding in addiction outcome research: people who engage with structured aftercare for 12 months or more after their primary treatment episode have dramatically better long-term outcomes than those who treat treatment as a one-off. Strong aftercare is rarely one thing — it's a stack: weekly counselling tapering over months, peer support (SMART Recovery, AA, NA, CA), continued GP and addiction-medicine follow-up, ongoing medication where relevant, and a written relapse-prevention plan. When evaluating any program, the question "what does aftercare look like in the 12 months after I leave?" is the single most predictive question you can ask.

What the evidence says about treatment length

Outcome studies in Australia and internationally consistently find that treatment length matters more than treatment type. People who stay engaged with structured treatment for 90 days or more — across any combination of detox, residential, and outpatient formats — have substantially better long-term recovery outcomes than people whose treatment ends at 28 days. This is partly biological (neuroplasticity in early recovery takes time) and partly social (rebuilding routines, repairing relationships, learning to live without the substance is a slow process).

The single most consistent finding across the addiction outcome literature is the importance of structured aftercare in the 12 months following primary treatment. Strong aftercare is rarely one thing; it is a stack — weekly counselling tapering over months, peer support (SMART Recovery, AA, NA, CA), continued GP and addiction-medicine follow-up, ongoing relapse-prevention medication where relevant, and a written relapse-prevention plan. People who engage with structured aftercare for 12+ months have dramatically lower relapse rates than people who treat their primary treatment as the entirety of recovery.

When you are evaluating any treatment program, the question "what does aftercare look like in the 12 months after I leave?" is one of the most predictive of long-term outcomes you can ask. Programs with vague or thin aftercare answers — regardless of how impressive the residential component looks — should be approached with caution.

Public, NGO, and private — across every treatment format

Almost every conversation about treatment in Australia comes down to a three-way choice between public, NGO (non-government organisation), and private treatment. The differences are real, but they aren't the marketing differences you usually read about. Here's how each sector actually works.

Public services

Public addiction medicine — delivered by state health systems and large public hospitals — is free at the point of access for Medicare-eligible Australians. It is genuinely high quality: addiction medicine is a recognised specialty, public detox units are staffed by specialist clinicians, and the underlying treatment models (CBT, motivational interviewing, medication-assisted treatment for opioids and alcohol) are evidence-based and current. The trade-off is access. Wait times for non-urgent residential admissions typically run from one to several weeks, with prioritisation for crisis presentations: pregnancy, post-overdose, severe co-occurring mental health crises, homelessness, child-protection involvement. If your situation fits one of those priorities, public can be remarkably fast.

NGO (non-government) providers

NGO services — Salvation Army Bridge, Odyssey House, Lives Lived Well, Cyrenian House, We Help Ourselves, Holyoake, Karralika, and many others — sit between public and private on cost and access. Many run on partial government funding plus client contributions, with sliding-scale fees. Some are free. NGO providers run a disproportionate share of Australia's longest-established residential rehabs and many of the country's most successful 60- and 90-day therapeutic communities. They also run most of the specialist programs you can't easily access elsewhere: women-only programs, parents-with-children programs, Aboriginal-specific services, and youth programs. Wait times are typically shorter than public, longer than private — usually one to three weeks for non-urgent admissions.

Private rehab

Private inpatient rehab admits within days, offers single-room accommodation, higher staff-to-client ratios, and typically charges $25,000–$45,000 for a 28-day program — sometimes meaningfully more for premium facilities. Private health insurance with hospital cover and psychiatric inclusion can offset between $400 and $700 per day, leaving an out-of-pocket cost in the $10,000–$25,000 range on a 28-day program. Private isn't automatically better than public or NGO; outcome studies consistently find that the two strongest predictors of long-term recovery are program length and aftercare engagement, not price band. What private buys is access, comfort, and a higher staff-to-client ratio — none of which is unimportant, but none of which is treatment quality on its own.

How to actually decide

The most useful first call in any of the three pathways is your state alcohol and drug line — they know all three sectors personally, can match you to wait times and program features, and have no commercial stake in which option you choose. From there, calling two or three specific providers to compare program length, clinical staffing, aftercare, and cost is the next step. The right choice depends on three things: severity of dependence, stability of your home environment, and what you can afford. Severe physical dependence with unsafe withdrawal needs medically supervised detox first. Unstable home environment usually points toward residential. Stable home plus moderate dependence usually suits outpatient. None of those rules are absolute.
