Allied Health Assistants (AHA): Skilled Support That Extends Therapy — and Lowers Costs
Allied Health Assistants (AHAs) work with therapists to deliver hands-on practice, carry out therapy programs, and help families get better outcomes — often at a fraction of the cost of additional therapist hours. Whether you’re searching for an Allied Health Assistant job or exploring how a therapy assistant can support your child, AHAs are an affordable and effective way to increase therapy dosage while keeping within your NDIS budget.
Allied Health Assistants (AHAs) are trained, supervised team members who implement therapy activities designed by registered Allied Health Professionals (AHPs). Under AHP supervision, the AHP remains responsible for assessment and clinical decisions; the AHA provides consistent, real-world practice that maximises your budget and delivers measurable results.

What Is An AHA?
An Allied Health Assistant (AHA) is a trained support worker who assists allied health professionals by delivering therapy activities planned and supervised by a qualified therapist. AHAs do not diagnose, change treatment plans, or perform formal assessments — they extend the therapist’s reach by providing additional, supervised practice and everyday support.
Training & Eligibility
Many AHAs are allied health students (speech, physio, OT) or graduates with a Certificate IV in Allied Health Assistance.
Employers commonly require background checks (Working with Children Check), basic first aid & vaccinations.
AHAs receive onboarding + ongoing supervision from an AHP.

How AHAs Fit Into The Therapy Team
AHAs increase the frequency of practice and help families apply therapist strategies in everyday routines — improving generalisation and progress between therapy appointments.

Benefits of Using an Allied Health Assistant
Allied Health Professionals (AHPs) focus on high-value clinical tasks. Many high-volume activities—repetition, coaching, equipment setup—can be safely delegated to an AHA under AHP supervision. This model not only boosts therapy impact but also creates AHA cost savings for families and the NDIS.
Frequent, consistent practice accelerates skill acquisition and generalisation.
AHAs are paid at lower hourly rates than registered therapists, allowing the same budget to buy more supervised hours.
Home, school or community sessions at times a therapist may not be available.
AHAs reinforce strategies so parents/carers feel confident implementing programs daily.
More frequent, guided practice usually shortens the time needed to reach goals — reducing long-term costs.
Maximise Your Budget
Working with both an AHP + AHA means significantly more therapy hours without increasing budget. Use the figures below as a guide, then map it to your own plan with our calculator.

FAQs
No. An Allied Health Professional (AHP) — such as a speech pathologist, occupational therapist, psychologist, or physiotherapist — is always responsible for assessment, diagnosis, and developing the therapy plan. The AHA works under AHP supervision, carrying out the activities set by the therapist. This means your therapist remains in charge of clinical decisions, while the AHA provides the hands-on practice and feedback that helps families achieve goals more consistently.
In most cases, yes. AHA time is commonly funded under Capacity Building supports in your NDIS plan (for example, Improved Daily Living) and is billed at the NDIS therapy-assistant rate — lower than a registered therapist’s. We’ll confirm how it fits your plan before we start, whether you’re self-managed, plan-managed, or NDIA-managed.
Your AHP sets clear, measurable goals and the AHA records data every session — what was practised, how your child responded, and progress toward each goal. Your therapist reviews this data regularly and adjusts the program, so you always know what’s working and what comes next.
Yes. AHAs can deliver supported practice and coaching over secure video for families who prefer it or live outside our clinic areas — either as the main format or alongside in-home, school, and clinic sessions.
