We have written twice about what this Act does to particular sections: how a participant asks for a decision to be reviewed, which the Act reaches from tomorrow, and the wider accountability picture. This is the thing underneath both: when. A provider or a participant asking whether a rule applies to them today needs the commencement table, and the commencement table is on page 2 of a 151 page Act.
Every date, and what the Act calls the part that starts on it
The table below pairs column 3 of the Act’s commencement table with the part headings from its own contents page. The wording in the right-hand column is the Act’s, not ours.
| Date | Provisions | The Act’s own heading for them |
|---|---|---|
| 20 Aug 2026 | Sections 1 to 4, Schedule 5 | Transitional rules |
| 27 Aug 2026 | Schedule 1, Parts 1 to 3 | Defining functional capacity; Limit unscheduled plan reassessments; Strengthen link between an impairment and need for support |
| 27 Aug 2026 | Schedule 2, Parts 1 to 4, 7 and 9 | Registration of NDIS providers; Civil penalties and regulatory powers; Information gathering powers; Retention of records; Immunity from producing documents or information; Additional penalties for fraudulent conduct |
| 27 Aug 2026 | Schedule 3, Parts 1 to 3, and Schedule 4 | Decision-making on pricing; Automation of administrative action; Minor amendments; New framework planning |

| 20 Nov 2026 | Schedule 2, Part 8 | Prohibition on inducements |
| 1 Dec 2026 | Schedule 2, Part 5 | Reducing claim times |
| 1 Feb 2027 | Schedule 1, Parts 5 and 6 | Plan renewal; Reasonable and necessary supports |
| 20 Feb 2027 | Schedule 3, Part 5 | Debt recovery |
| 1 Jul 2027 | Schedule 3, Part 4 | Whistleblower protections |
| 1 Jan 2028 | Schedule 1, Parts 8 and 9 | Tightening meaning of permanence to reduce access; Eligibility based on access to other services |
| No date | Schedule 2, Part 6 | Registered plan management providers |
Bold marks the three rows this article discusses: the next commencement, the last one, and the part with no date. Dates from column 3 of the section 2 commencement table. Part headings from the Act’s contents pages. A part heading describes a part; it is not the operative text, and this article does not report what any part actually does.
The access tests are scheduled last
Read the first column downward and the sequencing is hard to miss. The fraud and enforcement machinery commenced almost immediately, seven days after assent: provider registration, civil penalties and regulatory powers, information gathering, record retention, extra penalties for fraudulent conduct. So did pricing decision-making and the automation of administrative action.
The two parts whose headings describe narrowing who gets in are at the far end.
Tightening meaning of permanence to reduce access
and Eligibility based on access to
other services
both commence on 1 January 2028, sixteen months after the
Act received assent and the last date in the table.
There is a straightforward reading of that: those changes need rules, systems and transition, and the Act gives them the longest runway. There is also a less comfortable one, that the measures most likely to remove people from the scheme are the ones furthest from the news cycle that passed the Act. The Act does not say which, and neither do we. What we can say is that a participant reading August’s coverage would reasonably have thought the access test had already changed, and it has not.
Whistleblower protections arrive ten months after the penalties
The same table produces a second sequencing fact worth stating plainly.
Additional penalties for fraudulent conduct
and the civil penalty and regulatory powers
commenced on 27 August 2026. Whistleblower protections
, Schedule 3
Part 4, commence on 1 July 2027.
So for a bit over ten months, the enforcement regime aimed at fraud is running while the protections for people inside an organisation who report it are not yet in force. Both are in the same Act. We are reporting the order the Act sets, not asserting a consequence, and we have not read Part 4 closely enough to tell you what protection it will give when it arrives. That is a follow-up rather than a claim.
The part with no date
Item 9 of the commencement table covers Schedule 2, Part 6, headed
Registered plan management providers
. Its commencement column does not carry a date. It
reads: A single day to be fixed by Proclamation. However, if the provisions do not commence
within the period of 24 months beginning on the day this Act receives the Royal Assent, they
commence on the first day of the first calendar month to start after the end of that
period.
Assent was 20 August 2026, so the backstop is 1 September 2028. Between now and then this part commences whenever the government proclaims it, or not at all until that default date arrives. Plan managers cannot put it in a diary.
This is also where an independent check earns its keep. The Federal Register of Legislation publishes a machine-readable version list for the NDIS Act, one row per period the text is in force, each naming the provisions that ended the previous period. That list records exactly the seven future boundaries in the table above, from 1 October 2026 to 1 January 2028, and no row for Schedule 2 Part 6. The Register cannot list a boundary for a provision with no date, so the absence there is the same fact seen from the other side, and it is the reason we checked both sources rather than one.
Where the Act actually is today
The consolidated text has moved twice since the first tranche. Compilation No. 25, current when we wrote about review rights in August, ceased on 27 August 2026. Compilation No. 26 covered 27 August to 19 September. The current text is compilation No. 27, 470 pages, in force from 19 September 2026, and it ends tomorrow.
The 19 September change was not part of this Act at all. It came from the Knox Class Action (Facilitation) Act 2026, assented 18 September, which the Register records as amending the NDIS Act by a single item. We have not read it and make no claim about what it does; it is here because a reader checking a compilation number deserves to know why it moved.
What to do with this
If you are checking whether something applies to you, check the date first and the text second, and check which compilation you are reading. A provision that has passed Parliament, received assent and been reported as law can still be months away from binding anybody. On this Act that gap runs to sixteen months, and on one part it is open-ended.
The next four dates worth a diary entry are 1 October 2026, 20 November 2026, 1 December 2026 and 1 February 2027. We will read each tranche as it commences and report what changed, starting with support determinations and plan suspension tomorrow.
