Introduction to the NDIS
The National Disability Insurance Scheme (NDIS) provides vital support for Australians living with disability. It funds a broad range of supports designed to assist with daily life, independence, and long-term wellbeing.
https://www.ndis.gov.au
While the disability insurance scheme NDIS is designed to be participant-focused, the system can feel complex, particularly during the application stage.
Many applicants experience delays or unsuccessful outcomes not because they are ineligible, but due to small errors, missing documentation, or misunderstandings about how the NDIS system works.
This guide explains the most frequent NDIS application mistakes to avoid and highlights common mistakes, providing guidance on ow to navigate the process with confidence.
Understanding How the NDIS System Works
The NDIS is an insurance-based system, not a welfare payment.
Funding decisions are based on how a person’s disability affects their ability to complete daily tasks, manage daily life, and participate in the community.
Understanding this principle early helps applicants avoid common misunderstandings during the application process.

What an NDIS Plan Covers
An NDIS plan outlines the supports provided to a participant over a set period.
Plans typically include funding for:
- Core supports
- Capacity building supports
- Support coordination
Each plan also specifies how funding is managed. For practical advice on managing your NDIS funding, see these essential tips.

Understanding Plan Management Options
Choosing the right plan management option is critical.
Participants can choose between:
Self Managed
You manage providers, invoices, and payments yourself.
Plan Managed
A plan manager pays providers and helps track budgets on your behalf.
NDIA Managed
The NDIA pays registered NDIS providers directly.
Each option offers different levels of flexibility.
The NDIS explains plan management options in detail here:
https://www.ndis.gov.au/participants/using-your-plan/ways-manage-your-funding
Why Support Coordination Matters
Support coordination helps participants understand their plan and navigate the NDIS system.
Support coordinators assist with:
- Finding suitable providers
- Managing service delivery

- Mobility
- Communication
- Self-care / Personal Care

- Daily living activities
Guidance on functional evidence is available here:
https://www.ndis.gov.au/applying-access-ndis/how-apply/what-evidence-you-need

Eligibility criteria are explained here:
https://www.ndis.gov.au/applying-access-ndis/am-i-eligible
Mistake 4: Poor Preparation for NDIS Planning Meetings

Mistake 9: Poor Budget and Plan Management
Understanding plan management is key to effective funding use and ensures that NDIS participants to find providers and receive ongoing support.
Plan managers help track spending and ensure invoices are processed correctly.
Mistake 10: Ignoring Capacity Building Supports

Mistake 11: Not Requesting a Plan Review When Needs Change
Participants can request a plan review when circumstances change to adjust to their own life.

If a decision is incorrect, participants can request an internal review.
This allows the NDIA to reassess decisions based on additional evidence.
