Frequently asked questions
Is the 21-day rule from when I first call, or from later?
It runs from when the NDIA has your complete access request — meaning all the information and evidence it needs. If you call and start a request but evidence is still coming, the clock has not really started. It also pauses if the NDIA asks you for more information, which is why some applications feel slower than 21 days.
Does being found eligible mean my funding starts straight away?
Not immediately. Meeting the access requirements is a decision that you can join the Scheme. After that, the NDIA arranges a planning conversation to build your first plan, which can take a few more weeks. Your funding becomes available once that first plan is approved.
What is the most common reason applications get delayed?
Waiting on evidence. The NDIA usually decides quickly once it has everything, but reports from specialists and allied health professionals can take weeks to book and write. Submitting complete evidence that describes how your disability affects daily life — not just the diagnosis — is the best way to avoid back-and-forth.
Will the 2026 and 2027 reforms make applications slower?
The reforms mainly change how plans are built and reviewed, and how eligibility is assessed over time, rather than the 21-day access-decision rule. The new planning framework begins progressively from 1 April 2027 and functional-capacity eligibility from January 2028 at the earliest. Dates have shifted before, so confirm the current process with the NDIA.
What can I do if the NDIA has gone past 21 days?
Call the NDIA on 1800 800 110 and ask what stage your request is at and whether they are waiting on anything from you. If your complete request has clearly sat beyond the deadline, ask about the decision. If you are refused, you can request an internal review and then apply to the Administrative Review Tribunal, and a free advocate can help.
