When setting up your NDIS support plan in Blackburn or Bundoora, one of the most common questions is whether you should book every session with a Senior Occupational Therapist or utilize an Allied Health Assistant (AHA). Choosing between AHA vs OT for your weekly sessions isn’t about choosing “high quality” over “low quality.” Instead, it is about finding the right balance between clinical oversight and high-frequency practice.
At Posity, we believe the most successful participants use a “blended” model. By understanding the unique strengths of both roles, you can ensure your NDIS budget is used effectively while seeing the best possible results. Specifically, we use Allied Health Assistants to provide the consistent repetition needed to turn new skills into lifelong habits.

Understanding the Roles: Architect vs. Builder
The best way to look at the AHA vs OT debate is to look at the “scope of practice.”
- The Occupational Therapist (OT):
Think of the OT as the clinical architect. They possess the university qualifications to diagnose challenges, conduct Adult OT Assessment and Services, and design complex intervention plans. - The Allied Health Assistant (AHA):
Think of the AHA as the skilled builder. They work under the OT’s supervision to carry out the daily “heavy lifting” of the therapy plan. Specifically, they focus on the repetition and implementation of the goals the OT has set.
When to Choose an Occupational Therapist
While an AHA is fantastic for regular practice, there are specific times when a Senior OT is essential. Specifically, you need an OT for:
- Initial Assessments:
Whether it is paediatric occupational therapy for a new diagnosis or a Functional Capacity Assessment for an adult. - Complex Equipment Prescription:
Sourcing and trialing high-level assistive technology or home modifications. - Clinical Reviews:
Every 3–6 months, the OT should review your progress to adjust the “blueprint” the AHA is following.
When to Choose an Allied Health Assistant
For the vast majority of weekly sessions, an AHA is often the superior choice. Specifically, the AHA vs OT comparison favors the assistant when:
- Repetition is Key:
For Early Childhood Intervention (ECI), kids need to practice skills like drawing or dressing multiple times a week to see progress. - Community Integration:
An AHA can provide community occupational therapy by meeting you at the shops or school to practice social skills. - Budget Efficiency:
Because AHAs are more affordable, you can double your therapy hours. For occupational therapy for kids, this means more “play with purpose” sessions every month.
The “Blended” Model: The Best of Both Worlds
In 2026, the gold standard for NDIS care is the collaborative model. Specifically, your Senior OT sets the direction through Occupational Therapy Services, and your AHA delivers the weekly sessions.
We even utilize telehealth services to allow our OTs to “drop in” on an AHA session. This ensures that even during occupational therapy for adolescents focused on independence, the clinical standards remain high while the costs stay low. This approach ensures that no matter who is delivering the session, the participant is always moving toward their goals in a safe, evidenced-based way.
