Secure dementia (Memory Support Unit) — Australian aged-care providers + guide
A Secure Dementia Unit, also called a Memory Support Unit (MSU), is a locked area within a residential aged-care home specifically designed for residents with dementia who wander, exit-seek or whose safety would be at risk in a standard care setting. Distinct from general dementia care – secure units add a physical environment + clinical regime built around residents whose cognitive decline has progressed to a stage where they cannot independently navigate doors and exits safely.

- ✓Secure dementia (Memory Support Unit) coverage is in development for our directory. Federal subsidies + ACQSC ratings apply to all Australian residential aged-care services equally.

- ✓You or your family member has a confirmed dementia diagnosis with active safety concerns: wandering away from home, exit-seeking from current placement, falls due to disorientation, unable to recognise familiar people consistently. Mild cognitive impairment or early dementia without these safety markers does NOT require a secure unit and many people live well in mainstream residential care or HCP-supported at home for years.
In depth
What secure dementia (memory support unit) actually means
Secure dementia units typically house 14–24 residents in a dedicated wing or floor, with controlled access at all entry/exit points (key-fob or coded entry, never visible padlocks). Environment design follows the Dementia Centre at HammondCare principles: short corridors with clear sightlines to nursing stations, secure gardens with circular walking paths (avoiding dead-end frustration), contrasting colours for floor-vs-wall (depth perception declines with dementia), and quiet hours protocols to manage sundowning.
Clinical practice in a secure dementia unit prioritises non-pharmacological behaviour management: reminiscence therapy, sensory rooms, music + pet-therapy, light-cycle management. Antipsychotic prescribing rates are a key quality indicator – lower is generally better and is publicly reported in the ACQSC Quality Indicator program. Care minutes typically exceed the federal target of 215 minutes/resident/day, often running 230–260 minutes with a higher RN-to-resident ratio at night.
Entry to a secure dementia unit requires a formal dementia diagnosis + an ACAT recommendation for secure care, plus written consent from a legally-appointed substitute decision maker (Enduring Power of Attorney, Enduring Guardian or similar – varies by state). Detention without consent is unlawful; this is one of the most legally-sensitive areas of Australian aged care. Each state's Public Advocate or Civil and Administrative Tribunal can review contested placements.
Cost is the same as general residential aged care – secure dementia placement is funded via the resident's AN-ACC classification (Australian National Aged Care Classification), with higher dementia care needs translating to higher federal subsidy paid to the provider. The resident continues to pay the standard basic daily fee + means-tested fee + RAD/DAP. There is no "secure unit premium" on accommodation cost.
Quality markers to look for
- Locked / controlled-access wing within a residential aged-care home
- Typically 14–24 residents per unit; smaller is generally better
- Dementia-specific environment design (sightlines, gardens, contrasting colours)
- Higher care minutes than the federal target (often 230–260 vs 215)
- Non-pharmacological behaviour management as default; low antipsychotic rates
- Requires formal dementia diagnosis + substitute decision-maker consent
- Same cost as general residential aged care; no accommodation premium
Choose this care type if
You or your family member has a confirmed dementia diagnosis with active safety concerns: wandering away from home, exit-seeking from current placement, falls due to disorientation, unable to recognise familiar people consistently. Mild cognitive impairment or early dementia without these safety markers does NOT require a secure unit and many people live well in mainstream residential care or HCP-supported at home for years.
Cost
Same federally-regulated cost structure as mainstream residential aged care: basic daily fee $66.80/day, means-tested fee 0–$32,718/year based on income/assets, RAD/DAP for accommodation (varies by room + provider, typically $400k–$900k). The dementia-related higher care needs translate to a higher AN-ACC classification + higher federal subsidy paid to the provider, but no additional cost is passed to the resident or family beyond standard residential fees.
Common questions
Secure dementia (Memory Support Unit) — common questions
How is a secure dementia unit different from general dementia care?
General dementia care can be delivered within a mainstream residential aged-care home with appropriate staff awareness + care planning. A Secure Dementia Unit (MSU) adds a locked physical environment for residents whose cognitive decline has progressed to a point where they cannot safely navigate exits independently. The progression is typically: mainstream care → general dementia care → secure unit, though many residents never need the secure setting.
Is locking my parent in a secure unit ethical or legal?
It is lawful in Australia only with the right consent + clinical justification. A dementia diagnosis + ACAT recommendation + substitute decision-maker consent (Enduring Power of Attorney or Enduring Guardian, depending on state) are required. Detaining a person without these is unlawful. Most states have a Public Advocate or Tribunal that can review contested placements. The ethics rest on balancing safety vs liberty – a wandering person with advanced dementia is at very high risk of harm in the community; secure placement is generally the least-restrictive safe option once that point is reached.
What if my parent improves and no longer needs a secure unit?
Reassessment is required – typically conducted at least annually but on family/clinical request at any point. If the safety markers (wandering, exit-seeking) no longer apply, the resident can move to a mainstream room within the same facility or to a different facility. In practice dementia is a progressive condition + reversal is rare, but functional improvement after acute illness (e.g. UTI resolved) can sometimes reduce restlessness sufficiently to allow mainstream placement.
How do I assess the quality of a secure dementia unit?
Tour at least three times, including once at evening (sundowning is the highest-distress period). Check: care minutes specifically for the unit (target above the 215-minute federal mandate), 24/7 RN coverage, antipsychotic prescribing rate (lower is better; ACQSC publishes this), staff dementia-specific training (Dementia Australia or Dementia Training Australia certifications), environment design (sightlines, garden access, quiet rooms), most recent ACQSC Quality Indicator report for the service.
Can my parent have visitors in a secure unit?
Yes – secure units restrict resident exits, not visitor entry. Family + friends visit normally during the home's standard visiting hours, and most providers welcome family involvement throughout the day. Some units provide a "family room" for longer visits + overnight stays. Visiting consistency is one of the strongest non-pharmacological supports for dementia residents – regular visits from familiar people reduce distress + slow functional decline.
