NDIS Supports for Acquired Brain Injury (ABI): Provider Registration and Documentation Guide

Understanding ABI in the NDIS Context

Acquired brain injury (ABI) refers to any damage to the brain that occurs after birth. This includes traumatic brain injury (TBI) from accidents and falls, stroke, hypoxic brain injury (oxygen deprivation), brain tumours, encephalitis, and other neurological conditions. ABI is distinct from developmental or congenital brain conditions — it represents a sudden change in a person's functional capacity that often requires lifelong support.

Under the NDIS Act 2013, a person with ABI may access the NDIS if their brain injury results in a permanent impairment that substantially reduces their functional capacity in one or more areas of daily life (Section 24 — disability criterion). Some people with recent ABI may also access the NDIS under the early intervention criterion (Section 25) if early, intensive rehabilitation supports are likely to reduce their future support needs.

ABI participants represent a significant cohort within the NDIS. According to NDIS data, approximately 25,000 active participants have ABI as their primary disability. However, many more participants have ABI as a secondary condition alongside other disabilities. The average NDIS plan for an ABI participant with SIL is among the highest value plans in the scheme, often exceeding $200,000 per year due to the intensity and complexity of support required.

Why ABI is uniquely complex for providers

ABI differs from many other disability types because:

• Every brain injury is different — two people with TBI may have completely different functional impacts depending on the location and severity of the injury
• Cognitive impairment is often invisible — participants may appear physically capable but have significant memory, executive function, or behavioural challenges
• Recovery trajectories vary — some participants improve significantly over years while others plateau early, requiring ongoing support adjustment
• Neurobehavioural challenges are common — impulsivity, aggression, disinhibition, and lack of insight can create complex support situations that require specialist training
• Medical complexity — many ABI participants have ongoing medical needs (seizure management, PEG feeds, tracheostomy care) that require clinical competence from support staff
• Interface with the health system — the boundary between NDIS-funded disability support and state-funded health/rehabilitation services is often contested for ABI

Registration Requirements for ABI Providers

Because ABI participants access such a wide range of supports, providers may need registration across multiple registration groups. The specific groups depend on the type and intensity of support you deliver.

High Intensity Support Requirements for ABI

The NDIS Practice Standards — High Intensity Daily Personal Activities supplementary module applies to providers delivering supports that involve complex clinical care. For ABI participants, high intensity supports are common and include:

Clinical care tasks requiring high intensity registration

• Seizure management — administering rescue medication (midazolam), monitoring seizure activity, post-seizure care. Many ABI participants develop post-traumatic epilepsy
• PEG (Percutaneous Endoscopic Gastrostomy) feeding — enteral nutrition for participants with swallowing difficulties resulting from brain injury
• Tracheostomy care — suctioning, tube changes, and monitoring for participants who required tracheostomy during acute care
• Complex wound management — pressure injury care for participants with reduced mobility or sensation
• Ventilator management — for participants with respiratory compromise following severe brain injury
• Subcutaneous injections — including insulin management for participants with diabetes complicated by ABI-related executive function impairment

Staff competency requirements

The High Intensity module requires providers to demonstrate that staff delivering clinical care tasks have:

• Current competency assessment for each clinical task they perform
• Training delivered or supervised by a registered nurse or medical practitioner
• Annual competency reassessment documented in the training register
• Access to clinical guidance protocols and escalation procedures
• A clear understanding of when to escalate to nursing or medical staff
• Current first aid and CPR certification

For small providers, the high intensity requirements can be challenging to meet. You must have documented clinical governance arrangements — typically a registered nurse who provides clinical oversight, develops care plans, and assesses staff competency. This nurse does not need to be employed full-time; many small providers contract a registered nurse for clinical governance on a part-time or consultancy basis.

SIL for ABI Participants

Supported Independent Living is one of the most common NDIS supports for people with moderate to severe ABI. SIL provides the ongoing, day-to-day support that enables a person with brain injury to live in the community rather than in a hospital or aged care facility.

SIL arrangements for ABI

SIL for ABI participants typically involves one of the following arrangements:

• Shared living — two to five participants living together in a house with rostered support staff. This is the most common SIL arrangement and allows support costs to be shared between participants
• Individual living — one participant living alone with dedicated support staff. This is appropriate for participants whose neurobehavioural challenges make shared living unsuitable
• Transitional living — time-limited SIL arrangements designed to build a participant's independent living skills with the goal of reducing support intensity over time

Documentation requirements for SIL

SIL providers must maintain extensive documentation for each participant:

• SIL service agreement signed by the participant (or their nominee/guardian)
• Individualised support plan detailing daily routines, support needs, and NDIS plan goals
• Roster of care showing staffing arrangements and support ratios
• Progress notes for every shift documenting supports delivered and participant outcomes
• Medication administration records (if applicable)
• Incident reports for any reportable incidents
• Behaviour support plans (if the participant has neurobehavioural challenges)
• Clinical care plans for any high intensity supports
• House safety inspection records (at least quarterly)
• Shift handover documentation

Neurobehavioural Challenges and Behaviour Support

Neurobehavioural challenges are among the most difficult aspects of ABI support. Brain injury can cause significant changes to personality, behaviour, emotional regulation, and social functioning. These changes are not the participant's choice — they are a direct consequence of neurological damage.

Common neurobehavioural presentations in ABI

Behaviour support obligations

If an ABI participant's neurobehavioural challenges require the use of any restrictive practices — including environmental restrictions, seclusion, physical restraint, chemical restraint, or mechanical restraint — the provider must:

1. Engage a registered behaviour support practitioner to complete a functional behaviour assessment
2. Develop an interim behaviour support plan (within one month of a restrictive practice being first used)
3. Develop a comprehensive behaviour support plan (within six months)
4. Lodge the behaviour support plan with the NDIS Commission
5. Report every use of a restrictive practice to the NDIS Commission through the provider portal
6. Work toward the reduction and elimination of restrictive practices over time

Rehabilitation Focus in NDIS Documentation

A key difference between ABI and many other disability categories is the role of rehabilitation. While ABI results in permanent impairment, many participants continue to improve over years — particularly in the first two to five years after injury. NDIS documentation for ABI should reflect this rehabilitation focus.

Documenting progress and recovery

Progress notes and support plans for ABI participants should capture:

• Baseline functioning — what the participant could do at the start of the reporting period
• Current functioning — what the participant can do now, using specific, measurable descriptions
• Gains and improvements — any skills regained or new strategies learned
• Plateau indicators — if a participant's progress has plateaued in a specific area, this should be documented objectively
• Rehabilitation strategies in use — memory aids, cognitive strategies, physical rehabilitation exercises, communication supports

The NDIS and state health system interface

One of the most contentious areas for ABI providers is the boundary between NDIS-funded disability supports and state-funded health services. The general principle is:

• State health system covers acute medical treatment, inpatient rehabilitation, and post-acute rehabilitation up to the point where the person's condition stabilises
• NDIS covers ongoing disability-related supports once the person's condition has stabilised and they have been assessed as meeting the NDIS access criteria

In practice, the transition is rarely clean. Many ABI participants are discharged from hospital before their NDIS plan is in place, creating a gap in support. Providers must document any interface issues and work collaboratively with hospital discharge teams, rehabilitation services, and support coordinators to ensure continuity of care.

Writing Progress Notes for ABI Participants

Progress notes for ABI participants must capture both the supports delivered and the participant's functional performance in a way that demonstrates compliance with the NDIS Practice Standards and supports the participant's plan review process.

Cognitive impairment documentation

Many ABI participants have cognitive impairment affecting memory, attention, executive function, or processing speed. Document cognitive functioning using observable, specific language:

Neurobehavioural documentation

When documenting neurobehavioural incidents, follow the ABC framework: Antecedent (what happened before), Behaviour (what the participant did — in objective, observable terms), and Consequence (what happened after, including staff response).

Example: "At 14:30, another resident turned on the television loudly (antecedent). Chris raised his voice, stood up from the table, and kicked the chair (behaviour). Staff used a calm, low voice to acknowledge Chris's frustration, offered to relocate to a quieter space, and Chris agreed. He moved to his bedroom and listened to music for 20 minutes before returning to the common area (consequence). No restrictive practice was used. The incident has been recorded in the incident register."

Rehabilitation progress documentation

Progress notes should link to rehabilitation goals in the participant's NDIS plan:

• "Goal 2: Increase independence in meal preparation. Today, Sarah independently prepared a sandwich for lunch, selecting ingredients from the fridge and using a knife safely. Six months ago, Sarah required full physical assistance with meal preparation. Progress: significant improvement."
• "Goal 4: Improve community access skills. Tom completed a supervised walk to the local shops (400m). He identified the pedestrian crossing independently and waited for the green signal without prompting. Last month, Tom required verbal prompting at each crossing."

The NDISCompliant Notes Rewriter can help you transform raw shift notes into structured, goal-linked documentation that meets audit requirements. It supports Standard, SOAP, DAP, and Brief note formats.
