What is a secure memory support unit (MSU) for dementia?
A secure memory support unit is a specialised part of an aged care home for people with dementia who need additional supervision and a safer environment. The best units combine security with skilled dementia care, meaningful activity, familiar routines and the least possible restriction on the person’s freedom.

Key points
- Make sure the service can safely meet the person's current and likely future needs.
- Individual eligibility, availability and outcomes can vary.
- Ask questions early and seek independent help if anything feels unclear or unsafe.

01Guide sectionWhat is a secure memory support unit for dementia?
A secure memory support unit, sometimes called an MSU, dementia care unit or secure dementia unit, is a specialised area within an aged care home for people living with dementia who need additional support and a safer environment.
It usually has controlled entry and exit points to reduce the risk of a resident becoming lost or leaving the home without the support they need.
02Guide sectionWho might need a memory support unit?
An MSU may suit a person who:
frequently becomes disoriented or lost
attempts to leave the aged care home without understanding the risks
needs close supervision throughout the day or night
has difficulty recognising unsafe situations
experiences distress, agitation or other changes in behaviour
needs a predictable environment and staff experienced in dementia care
cannot be supported safely in a general residential aged care area.
A dementia diagnosis alone does not mean someone must live in a secure unit. Many people with dementia can live safely in a standard part of an aged care home with suitable support.
The decision should be based on the person’s individual needs, risks, preferences and abilities-not simply the diagnosis.
03Guide sectionWhat does “secure” mean?
A secure unit may use features such as:
coded or electronically controlled doors
enclosed gardens and walking areas
safe indoor paths for residents who like to walk
clear signs, colours and visual cues
layouts designed to reduce confusion
alarms or monitoring systems
secure access to potentially dangerous areas.
The aim should be to create a safe and supportive environment while allowing residents as much freedom of movement as possible.
Living in a secure unit does not remove a person’s rights. Any restriction on movement must be necessary, proportionate and handled in accordance with aged care law. Restrictive practices must be a last resort, used in the least restrictive form and for the shortest possible period.
04Guide sectionWhat care should an MSU provide?
A good memory support unit should provide more than locked doors.
It should offer:
workers trained and experienced in dementia care
24-hour care and access to nursing
individualised care planning
consistent routines and familiar workers
support with personal care, medication, meals and mobility
meaningful activities suited to the person’s interests and abilities
support for communication, anxiety and distress
safe access to outdoor areas
involvement of family and trusted supporters
regular reviews as the person’s needs change.
Aged care homes can provide specialised dementia care alongside everyday support, personal care and clinical services.
05Guide sectionDoes an MSU use restraint?
A secure environment can limit a resident’s ability to leave, so families should ask how the home protects freedom, dignity and choice.
Physical, environmental or chemical restraints must not be used simply because they make care easier for staff. Restrictive practices should only be used as a last resort after other approaches have been considered, with appropriate consent, documentation and monitoring.
Where a resident experiences significant distress or changed behaviour, the home should investigate possible causes, such as:
pain
infection or illness
medication side effects
hunger or thirst
fear or confusion
excessive noise
disrupted routines
unmet communication or cultural needs.
The response should be tailored to the person rather than relying automatically on sedation or restriction.
06Guide sectionWhat should I look for when visiting?
Ask to see the unit rather than relying on the provider’s brochure.
Look for:
residents being treated calmly and respectfully
staff speaking with residents rather than about them
adequate staffing and visible supervision
secure but accessible gardens
natural light and spaces that are easy to navigate
meaningful activities rather than residents sitting unattended
clean, quiet and comfortable surroundings
bedrooms that can be personalised
clear processes for involving family
staff who can explain how they manage distress without unnecessary restraint.
Dementia Australia recommends checking whether workers have dementia-specific skills, care is tailored to each resident and the environment is genuinely dementia friendly.
07Practical actionQuestions to ask the aged care home
Ask:
Why do you believe this person needs a secure unit?
What dementia-specific training do workers receive?
How many staff are present during the day and overnight?
Will the person usually see familiar workers?
How do you respond when someone wants to leave?
How do you manage distress, agitation or aggression?
How often are medications and behaviour-support strategies reviewed?
Is there safe outdoor access?
How are families involved in care planning?
Can the person move to a less secure area if their needs change?
Are respite stays available in the unit?
What happens if the person’s behaviour or clinical needs become more complex?
08Guide sectionHow do I access a memory support unit?
The person generally needs approval for permanent residential aged care or residential respite through an aged care assessment.
After approval, families can use My Aged Care to identify homes offering secure dementia or memory support places. Availability varies, and some homes have waiting lists.
A memory support unit is not a separate government funding program. It is a specialised residential care environment offered by some aged care homes.
09Guide sectionWhat should I do next?
Confirm the details with My Aged Care or the relevant provider, write down your questions and ask for important information in writing before making a decision.
