Home Modifications for Dementia in Australia: Funding and Design

Falls are the leading cause of injury-related hospitalisation for older Australians, and a parent with dementia faces significantly higher fall risk due to impaired spatial awareness, poor depth perception, and medication side effects. The right home modifications can delay or prevent the transition to residential care — but most families do not realise the Australian Government will fund up to $15,390 in modifications through the Support at Home program.

The AT-HM Scheme: Three Tiers of Funding

The Assistive Technology and Home Modifications (AT-HM) scheme operates under Support at Home and is available to anyone approved for ongoing home care services. It works across three tiers, each covering different levels of modification:

Low tier (up to $513): Covers basic safety items over a rolling 12-month period. Think non-slip bath mats, lever door handles to replace round knobs (easier for arthritic or confused hands), key safes for carer access, and motion-sensor night lights that reduce disorientation during nighttime bathroom trips.

Medium tier (up to $2,052): Covers moderate equipment and minor installations. This includes grab rails in bathrooms and along hallways, ramp thresholds to eliminate trip hazards at doorways, standard manual wheelchairs, and simple personal alarm systems. For a parent with dementia, this tier is where most bathroom safety modifications sit — a critical area, since wet-floor falls in bathrooms account for a disproportionate share of serious injuries.

High tier (up to $15,390): Covers major structural modifications and complex clinical equipment. This is where significant dementia-specific modifications live: accessible bathroom refits (walk-in showers replacing bathtubs), wheelchair ramps, widened doorways, and stairlifts. A clinical prescription from an occupational therapist (OT) is required. Additional funding beyond $15,390 is accessible with further clinical justification, but the high-tier home modification allocation is a once-off lifetime allocation.

Participants in remote areas (Modified Monash categories MM 6 and MM 7) receive a 50% supplement on top of standard AT-HM tiers, recognising the higher cost of trades and materials in remote locations.

Dementia-Specific Home Safety Modifications

General aged care modifications (grab rails, ramps) help, but dementia creates unique safety challenges that require targeted solutions:

Wandering prevention. Door alarms, sensor mats at exit points, and fence/gate locks are frontline modifications. The goal is not to restrict movement — which raises restrictive practices concerns — but to alert carers when your parent approaches an exit. GPS tracking devices worn as watches or pendants provide a safety net for parents who still walk independently but may become disoriented.

Kitchen safety. Stove isolation switches allow the stove to be disabled when your parent is unsupervised, without removing their sense of independence when a carer is present. Automatic kettle shut-offs and lockable knife drawers are simple additions that reduce serious accident risk.

Bathroom safety. Beyond grab rails, consider thermostatic mixing valves (preventing scalding from hot taps — a parent with reduced sensation may not react to dangerous water temperatures), raised toilet seats, and walk-in showers with fold-down seats. Contrasting colours between walls, floor, and fixtures help a parent with dementia distinguish surfaces — white toilet on a white floor against a white wall is genuinely dangerous for someone with impaired depth perception.

Lighting. Consistent, even lighting throughout the home reduces the shadows and dark patches that trigger visual hallucinations and spatial confusion. Motion-activated lights in hallways, bathrooms, and the path between bedroom and bathroom address the nighttime falls that commonly lead to hospital admissions.

How to Access AT-HM Funding

The process starts with your parent's Support at Home assessment or reassessment through the Single Assessment System. During the assessment, explicitly mention the specific safety risks you are managing — assessors need concrete examples (wandering incidents, falls, kitchen near-misses) to justify modification funding.

For medium and high-tier modifications, you will need an occupational therapist assessment. Your Support at Home provider can arrange this, or you can request an OT referral through your parent's GP. The OT will visit the home, identify hazards, and produce a prescription specifying the modifications needed and the clinical justification for funding.

Your chosen registered provider then manages the modification process: sourcing quotes, engaging tradespeople, and claiming the AT-HM subsidy. You do not need to arrange contractors yourself, though you can request specific tradespeople if you prefer.

Dementia-Friendly Home Design Principles

Beyond safety modifications, the way a home is organised significantly affects how independently a parent with dementia can function:

Reduce visual clutter. Remove rugs with busy patterns, unnecessary furniture, and decorative items from walkways. Clear sightlines between rooms help your parent navigate without confusion.

Use consistent routines in physical space. Keep everyday items (keys, wallet, glasses) in the same visible location. Label cupboards and drawers with words or pictures. A visible daily schedule or whiteboard in the kitchen can orient your parent in time when their internal clock falters.

Maintain familiar environments. Resist the urge to redecorate or reorganise. A parent with dementia relies on spatial memory that was laid down years ago. Moving furniture or changing room layouts can cause acute disorientation and distress.

Plan Modifications Before the Crisis

The Dementia Care in Australia toolkit includes a room-by-room home safety checklist and an AT-HM funding application guide — helping you identify what needs changing and access the funding to pay for it, before a fall forces the conversation.
