How Behaviour Support, Allied Health, and SIL Actually Work Together
Supported Independent Living (SIL) is often described as a service that helps NDIS participants live as independently as possible in their home. But in practice, SIL rarely operates on its own.
For many participants, particularly those with more complex support needs, the people providing day-to-day SIL support are one part of a much broader support network. Behaviour support practitioners, occupational therapists, speech pathologists, psychologists, physiotherapists, support coordinators, families and other professionals may all contribute to the participant's goals and wellbeing.
The important part is not simply having all these services involved. It is how well those services work together.
A behaviour support strategy may be clinically sound, but if support workers do not understand how to apply it during everyday situations, it may have limited impact. An occupational therapist may recommend changes to a participant's environment, but those recommendations need to become part of the participant's daily routines. A speech pathologist may introduce a new communication strategy, but it needs to be consistently recognised and used by the people supporting the participant.
This is where SIL can play an important role.
As a registered SIL provider, Sunnysights sees the value of connecting professional recommendations with what actually happens in a participant's home. Good SIL is not about replacing the work of allied health or behaviour support professionals. It is about creating an environment where their strategies can be understood, implemented and reviewed as part of everyday support.
SIL Is Rarely a Standalone Support
SIL provides assistance with everyday living for eligible NDIS participants who require support to live independently. Depending on the participant's needs, this might include assistance with personal care, household tasks, meal preparation, routines, community participation and developing daily living skills.
However, the support a participant needs to achieve greater independence may extend well beyond these practical tasks.
A participant might also work with:
A behaviour support practitioner to understand behaviours of concern and develop positive strategies for responding to them.
An occupational therapist to develop daily living skills, assess the home environment or recommend assistive technology.
A speech pathologist to support communication, social interaction or alternative and augmentative communication.
A psychologist to support emotional wellbeing, coping strategies and other aspects of a participant's mental health and development.
A physiotherapist to support mobility, physical function, exercise or safe movement.
A support coordinator to help bring different services together and make sure supports remain aligned with the participant's goals.
The participant sits at the centre of this network, with their NDIS Plan, personal goals and individual circumstances helping to shape the supports they receive.
The aim is not simply to have multiple services involved. It is to make sure those services are working towards outcomes that are meaningful to the participant, so they experience one coherent approach rather than a collection of disconnected services.
The Role of Behaviour Support Practitioners
Behaviour support practitioners can play an important role when a participant experiences behaviours of concern that affect their safety, relationships, routines or ability to participate in everyday life. Their work is generally focused on positive behaviour support, which looks beyond the behaviour itself to understand what may be contributing to it and how the participant can be supported in a respectful, proactive and person-centred way.
A Functional Behaviour Assessment (FBA) may be used to better understand the circumstances surrounding a behaviour, including what happens before and after it and what purpose the behaviour may be serving for the participant. This understanding can help inform practical strategies for reducing behaviours of concern and supporting alternative ways of communicating needs.
Depending on the participant's circumstances, the behaviour support practitioner may then develop Comprehensive Behaviour Support Plans that provide guidance for the people supporting the participant.
A Behaviour Support Plan can include:
identifying potential triggers or contributing factors
recognising early signs that a participant may be becoming distressed
developing proactive strategies
establishing appropriate responses to behaviours of concern
identifying communication or environmental changes that may help
supporting the participant to develop alternative skills or ways of communicating
providing guidance to the people who support the participant.
For a SIL provider, the Behaviour Support Plan is particularly important because support workers are often present during the everyday situations in which these strategies need to be applied.
Turning a plan into everyday support
One of the biggest differences between a written strategy and an effective strategy is what happens in the moment.
For example, a behaviour support practitioner may identify that unexpected changes to a participant's routine can contribute to distress. The recommended approach might include providing advance notice, offering choices and using a familiar visual schedule.
That advice becomes meaningful when the support team incorporates it into everyday life.
Instead of simply knowing that "routine changes are difficult", staff understand what they can actually do:
"The participant has been told that the usual activity is changing. We can explain what is happening, show them the alternative on their visual schedule and give them an opportunity to choose between the available options."
This is where communication between the behaviour practitioner and SIL team becomes valuable.
It also highlights an important distinction: support workers are not expected to become behaviour practitioners. Their role is to understand and consistently implement the strategies that have been developed for the participant, while providing feedback about what they observe in everyday situations.
Restrictive Practices and the Role of the SIL Team
Behaviour support can also involve situations where restrictive practices are relevant. Restrictive practices are highly regulated under the NDIS and should only be used in accordance with the applicable requirements and authorisation processes.
For a SIL provider, this makes communication particularly important. Support workers need to understand what is included in a participant's behaviour support plan, what their responsibilities are, and what they should do if a situation arises that they are not equipped to manage.
Importantly, the focus of contemporary positive behaviour support is not simply on managing behaviours of concern. Where restrictive practices are in use, there should also be a focus on reducing reliance on them and supporting the participant's rights, choice, dignity and quality of life.
This is another reason why the SIL provider, behaviour support practitioner and other members of the participant's multidisciplinary team need to communicate effectively. Day-to-day observations from support workers can help inform reviews and identify opportunities to strengthen proactive strategies.
How Allied Health Contributes to SIL
Allied health professionals can influence many aspects of how a participant lives and receives support.
Their recommendations may relate to communication, mobility, personal care, household activities, sensory needs, equipment, routines or developing greater independence.
Allied health professionals include Occupational Therapists (OT), Speech Pathologists, Physiotherapists and Exercise Physiologists.
Occupational therapy
An OT might identify that a participant can complete more household tasks independently with the right approach or equipment.
For example, an OT may recommend:
adapting the kitchen layout
introducing visual prompts
changing how household tasks are broken down
using assistive technology
modifying equipment
establishing a consistent routine for personal care.
The SIL support team can then incorporate these recommendations into everyday support.
Rather than staff simply completing a task for the participant because it is quicker, the support approach can focus on how the participant can be involved in the task and gradually develop their skills.
That distinction is important.
SIL is not simply about getting things done for someone. Where appropriate, it is also about creating opportunities for the participant to exercise choice, develop skills and increase their independence.
Speech pathology
Communication is another area where consistency can make a substantial difference.
A speech pathologist may recommend particular communication techniques, visual supports, communication devices or other strategies based on how an individual participant communicates.
For example, a participant might use a communication device to express preferences rather than relying on speech. If some people around them use the device consistently while others immediately answer questions for them, the participant receives mixed messages.
The SIL team can help reinforce the communication approach throughout the day by:
allowing sufficient time for the participant to respond
using agreed communication techniques
recognising the participant's preferred communication methods
incorporating communication supports into everyday routines
providing feedback when a strategy appears to be working or when difficulties arise.
Again, the SIL team is not replacing the speech pathologist. They are helping make the recommended approach part of everyday life.
Physiotherapy and other disciplines
The same principle applies to physiotherapy and other allied health services.
A physiotherapist may recommend exercises, mobility strategies or techniques for safe movement. Staff may then support the participant to incorporate these activities into their routine, where this is appropriate and consistent with the professional's recommendations.
A psychologist may recommend strategies for managing particular situations or supporting emotional regulation. A participant's support team can help create predictable routines and environments that reinforce those strategies.
Each professional brings a different area of expertise. Collaboration allows those areas of expertise to connect.
The Support Worker: Where Plans Meet Real Life
Support workers occupy a particularly important position within this system because they are often the people who see what happens in the participant's everyday life.
They may observe:
what happens before a behaviour of concern
which communication strategies work well
when a participant becomes overwhelmed
which daily living tasks they can complete independently
where additional prompting is needed
changes in routines, preferences or abilities
whether an environmental adjustment is helping.
This does not mean support workers should independently diagnose problems or change clinical strategies.
Instead, their observations can provide valuable information back to the professionals responsible for developing those strategies.
For example, an OT may recommend a particular approach to a daily living task. After several weeks, support workers might notice that the participant consistently struggles with one part of the process.
That information can be fed back to the OT.
Perhaps the task needs to be broken down differently. Perhaps the equipment is not suitable. Perhaps there is another factor affecting the participant's ability to complete it.
This creates a feedback loop:
Professional assessment → strategy → everyday implementation → observation → feedback → review
That loop is one of the most valuable parts of multidisciplinary support.
Why Consistency Matters So Much
Imagine a participant receives different messages from the people around them.
One support worker encourages them to complete a task independently. Another completes it for them because it is quicker. A therapist recommends a particular communication method, but staff continue using a different approach. A behaviour support strategy recommends giving the participant time to process information, while staff unintentionally rush them.
None of these individuals may be doing anything intentionally wrong.
The problem is that the participant is experiencing different approaches from different people.
Furthermore, consistency does not mean every interaction has to be identical. People have different personalities, and participants should have opportunities for choice and flexibility.
Instead, consistency means that everyone understands the important principles behind the participant's support.
For example:
What communication approach should we use?
What signs indicate the participant may be becoming distressed?
What strategies assist with emotional regulation?
How should staff encourage independence?
What should staff avoid doing?
What environmental factors support the participant?
When should concerns or changes be communicated to the relevant professional?
When these fundamentals are understood across the team, the participant is more likely to experience a predictable and supportive environment.
What Good Collaboration Looks Like in Practice
Effective collaboration does not necessarily mean every professional needs to be involved in every conversation.
In fact, excessive communication can become counterproductive if it creates unnecessary meetings and administration.
Good collaboration is more targeted.
It might involve a SIL provider:
Understanding the participant's current plans and recommendations Staff need access to the information they require to provide safe and appropriate support.
Making sure staff understand relevant strategies A plan is only useful if the people implementing it understand what it means in practice.
Communicating observations back to the appropriate professionals Staff can provide valuable information about what they are seeing in the participant's everyday environment.
Identifying changes early Changes in behaviour, challenging behaviour, communication, mobility, routines or independence may warrant discussion with the relevant professional.
Participating in reviews when appropriate When strategies are reviewed, the experiences of the participant and their support team can help inform what happens next.
Keeping the participant at the centre Collaboration should ultimately be about the participant's goals, preferences, safety, rights and quality of life, not simply about making services easier for providers to coordinate.
A Real-Life Example: Supporting Greater Independence
Consider a participant who wants to become more independent with preparing meals.
Their OT identifies that they have the physical and cognitive capacity to complete parts of the task but benefit from a structured sequence and some adaptations to the kitchen.
The OT recommends:
rearranging commonly used items
using visual prompts
breaking meal preparation into smaller steps
introducing suitable equipment
gradually reducing prompts as the participant becomes more confident.
The SIL team then incorporates these strategies into the participant's routine.
Initially, a support worker may provide significant prompting. Over time, staff record that the participant can independently complete several steps but consistently needs help with one particular part of the process.
That information is shared with the OT.
The OT can then reassess the approach and determine whether another adaptation or strategy would help.
The result is not simply that the participant has received OT and SIL.
The participant has a connected support system working towards the same outcome.
Another Example: Behaviour Support and Everyday Routines
Consider a participant who experiences distress when plans change unexpectedly.
Their behaviour support practitioner identifies that advance warning, clear communication and offering meaningful choices can help reduce distress.
The SIL team incorporates those strategies into everyday routines.
If an activity needs to change, staff provide information early where possible, explain what is happening and offer the participant appropriate choices.
Over time, staff notice that certain types of unexpected changes continue to cause difficulty. Rather than simply developing their own new strategy, they can communicate those observations back to the behaviour support practitioner.
The practitioner can then consider whether the existing plan needs to be reviewed or whether additional strategies should be explored.
This is an important part of the relationship between behaviour support and SIL: the practitioner brings specialist knowledge, while the SIL team brings knowledge of how the participant responds in their everyday environment.
The Role of Families and Support Coordinators
Families can also provide valuable insight, particularly where they have a long history of understanding the participant's communication, preferences, routines and behaviours.
However, collaboration should not mean that family members have to coordinate every professional themselves.
Support coordinators can often play an important role in helping connect different services and allied health professionals, particularly when a participant has several providers involved.
They may help identify gaps, coordinate communication and support the participant to make decisions about their services.
The exact responsibilities of each person will depend on the participant's circumstances and the services they have in place. What matters is that there is clarity about who is responsible for what.
A participant should not have to become the messenger between five different professionals.
When Collaboration Breaks Down
The opposite of a coordinated support system is not necessarily poor care. Often, it is simply fragmented care.
A participant may have excellent professionals around them, but if information is not shared appropriately, their support can still feel disconnected.
Common problems can include:
recommendations not being communicated to the SIL team
support workers not understanding why a strategy has been recommended
different providers using conflicting approaches
changes in a participant's circumstances not being communicated
outdated strategies continuing to be used
professionals making recommendations without understanding the participant's everyday environment.
These issues can be particularly challenging when staff turnover occurs or when new providers become involved.
This is why good SIL providers need systems for staff communication, handover, training, documentation and escalation, while also respecting participant privacy, consent and the boundaries of each professional's role.
Collaboration Should Not Mean Losing the Participant's Voice
There is another important consideration in multidisciplinary support: the participant should remain the decision-maker wherever possible.
It can be easy for professionals to start talking about a participant rather than talking with them.
A genuinely collaborative approach should include the participant's preferences, goals and communication style.
For some participants, this may mean directly participating in meetings. For others, communication may need to be adapted so they can express their views in a way that works for them.
The goal is not simply for professionals to agree with each other.
The goal is for the support system to work with the participant, rather than making decisions around them.
SIL as Part of a Bigger Support System
SIL works best when it is understood as one component of a broader support network.
A behaviour support practitioner may provide expertise in understanding behaviours of concern. Allied health professionals may provide strategies for developing skills, improving communication, mobility or independence. Support coordinators may help connect services. Families may contribute valuable knowledge about the participant. And support workers help bring appropriate strategies into the participant's everyday environment.
No single professional has to do everything.
In fact, the strength of a multidisciplinary approach comes from recognising that each person has a different role.
At Sunnysights, we believe effective SIL is about more than providing day-to-day assistance. It is about creating a supportive home environment where participants can build independence, exercise choice and work towards their goals.
That means working respectfully alongside participants, their families, support coordinators, behaviour support practitioners and allied health professionals to provide consistent, person-centred support.
If you are exploring SIL for yourself or a family member and want to understand how it could fit alongside existing supports, contact Sunnysights to discuss your circumstances and learn more about our approach to Supported Independent Living.
Frequently Asked Questions
Does SIL include behaviour support?
SIL and behaviour support are separate NDIS supports with different roles. A SIL provider may support a participant to implement strategies from their Behaviour Support Plan in everyday situations, but behaviour support itself is generally provided by an appropriately qualified behaviour support practitioner. The two services can work closely together when a participant's needs require it.
Can a behaviour support practitioner work directly with SIL staff?
Yes. Collaboration between a behaviour support practitioner and the SIL team can be particularly valuable when support workers are responsible for implementing strategies in the participant's everyday environment. This may involve explaining strategies, providing training or guidance, discussing observations and contributing to reviews, while maintaining the participant's privacy, consent and rights.
What happens if a Behaviour Support Plan is not working?
A Behaviour Support Plan should not be treated as a fixed document that can never change. If strategies are not producing the intended outcomes, the participant, SIL team and relevant professionals can communicate what they are observing and consider whether the approach needs to be reviewed. Changes in circumstances, communication, environment or the participant's needs may all be relevant. Support workers should provide observations rather than independently changing clinical strategies.
What is the difference between a Functional Behaviour Assessment and a Behaviour Support Plan?
A Functional Behaviour Assessment is a process used to develop a better understanding of why a behaviour may be occurring and what factors may be influencing it. The findings can then help inform a Behaviour Support Plan. In simple terms, the assessment helps build an understanding of the behaviour, while the plan sets out practical strategies for supporting the participant.
Who is responsible for training SIL staff in behaviour support strategies?
This depends on the participant's circumstances, the relevant plan and the roles of the professionals involved. Behaviour support practitioners may provide guidance or training relating to behaviour support strategies, while the SIL provider is responsible for ensuring its workers are appropriately prepared to perform their role. Clear communication about who provides training, what staff need to understand and how competency is maintained can help prevent gaps in support.
Can allied health recommendations be incorporated into a participant's SIL routine?
Yes, where the recommendation is relevant to the participant's SIL support and the SIL team is appropriately equipped to implement it. For example, an occupational therapist may recommend a particular approach to developing daily living skills, while a speech pathologist may recommend communication strategies. The SIL team can incorporate appropriate recommendations into everyday routines and provide feedback to the relevant professional about how the participant is responding.
What should I look for in a SIL provider when multiple professionals are involved?
Look for a SIL provider that understands the importance of multidisciplinary collaboration and has clear processes for communication, staff handover, documentation and implementing relevant professional recommendations. It is also important that the provider respects the participant's preferences and rights, understands the boundaries of its role, and is willing to communicate constructively with families, support coordinators, behaviour support practitioners and allied health professionals. The goal should be a consistent support environment centred on the participant's own goals.
