Updated 25 August 2026. The Bill this page describes is now an Act. It finally passed both Houses on 19 August 2026 and received assent on 20 August 2026 as Act No. 66 of 2026, and the Federal Register lists it as in force. The Senate agreed 32 government amendments before it passed. We have set out what the Senate changed, and when each part starts. That resolves the contingency this calendar was built on: the dates below were described as hanging on a Bill still before the Senate, and they no longer do. The Act commences in stages rather than all at once, and one date belongs on any calendar of this reform, the whistleblower protections the Senate added, which do not start until 1 July 2027. Changed today, and only these: the section Where the Bill has actually got to is a standing status section, so it now carries the concluded Senate stages, the House agreeing to the amendments, and assent, and the paragraph after it no longer says the Bill has not passed; the line describing the government's implementation dates as depending on the Bill passing now says that dependency is resolved while those dates remain the government's plan rather than commencement provisions in the Act. The calendar entries themselves, and the earlier dated note below, are left as published.

In force now: SIL registration, with a criminal penalty

From 1 July 2026, some supported independent living providers must be registered with the NDIS Commission. The Commission’s reform-hub page defines the captured cohort (a package of home and living support for people with higher support needs, where the person requires support for all or most of the day), creates a new registration group, 0138 – Assistance with supported independent living, and requires certification audits plus a new supplementary SIL module of the Practice Standards. The penalty language is unusually direct for a regulator’s explainer: Providing supported independent living without registration is a serious offence… The maximum penalty is 2 years’ imprisonment, a fine of 120 penalty units, or both.

Providers who applied before 1 July may keep operating while their application is processed. The next cliff is 1 October 2026: a provider that has not applied by then must stop delivering SIL and follow the Commission’s participant-transition steps. The March wave of registration refusals we found in the enforcement register is worth reading alongside this: registration is now both mandatory for SIL and actively policed at the application gate.

The same 1 July package tightened provider-sale scrutiny. Minister for the NDIS Jenny McAllister’s 30 June release announced that providers must now notify the Commission as soon as they become aware that a sale of a registered NDIS business will occur, with new audits on significant changes to governance or operations, aimed at ending the sale of “‘cleanskin’ registered businesses”. The Minister’s framing: These providers have a choice. They can shape up or ship out.

1 October 2026: Thriving Kids begins

Thriving Kids is the first phase of Foundational Supports, the supports all governments have committed to build outside the NDIS, alongside mainstream services. The Department of Health, Disability and Ageing’s pages carry the numbers: $10 billion in joint funding over 5 years for Foundational Supports overall, and within that a $4 billion, 5-year commitment for Thriving Kids, aimed at children aged 8 and under with developmental delay and/or autism and low to moderate support needs, and their families, carers and kin. At least $1.4 billion of the Commonwealth’s $2 billion share flows directly to the states to deliver services.

The department’s stated timeline: rollout of state services from 1 October 2026, at scale from 1 January 2028, with NDIS access changes for that cohort also commencing 1 January 2028 so that national services would be in place ahead of changes to NDIS access arrangements. Two design details matter for providers and allied health. First, children with permanent and significant disability, and those with high support needs, remain NDIS-eligible; Thriving Kids does not touch that cohort. Second, children already in the NDIS before 1 January 2028 will be reassessed under the eligibility criteria in place before that date, not the new rules. The access change itself still requires an amendment to the NDIS Act, which has not yet been made: a significant dependency sitting under the whole 2028 leg of the timeline. A House committee inquiry into Thriving Kids has reported (“No child left behind”), and the department states the government is considering it.

The Bill-dependent chain, to 2030

Updated 17 August 2026. This calendar said it would be kept current as dates move, and three had. The Senate committee reported on 14 August rather than being “still examining”, and the Bill has since been introduced in the Senate itself. A new section, Where the Bill has actually got to, now carries every recorded stage from the Parliament’s own page for the Bill, which has been added as a source. The Bill-dependent dates themselves are unchanged, because the Bill has not passed.

The government’s Securing the NDIS page sets out the implementation sequence for the changes in the Amendment Act (the committee reported on 14 August recommending passage; the positions on it are covered in our companion piece and the report itself in our verdict piece). Every date below is the government’s own stated intent for implementation. The Bill they depended on has now passed and received assent, so that dependency is resolved; these remain the government’s plan rather than commencement dates written into the Act.

  • Royal assent + 7 daysTighter criteria for unscheduled plan reassessments commence
  • 1 October 2026Social and community participation budgets “progressively adjusted”; a $200 million Inclusive Communities Fund announced alongside
  • 1 February 2027Reasonable-and-necessary and plan-renewal changes progressively implemented
  • 1 April 2027New framework planning rollout begins, delayed from an earlier date following consultation with people with disability and their families, carers and advocates, per the page itself
  • July 2027Provider registration expansion commences, full implementation by end of 2030
  • 1 October 2027New plan management approach implemented
  • 1 January 2028NDIS and mainstream-services boundary changes apply to prospective participants; Thriving Kids at scale; cohort access changes commence
  • 1 July 2028New commissioned support coordination function begins
  • 2026 to 2030NDIS claims and payments systems uplift, rolled out from July 2026 to the end of 2030

Where the Bill has actually got to

The dates above that depend on the Bill depended on it finishing in the Senate, and it has. As recorded on the Parliament of Australia’s page for the Bill, re-read on 25 August 2026:

  • House of Representatives: introduced 14 May 2026, second reading agreed 28 May, third reading agreed 2 July 2026.
  • Senate committee: referred 14 May, interim report 23 June, final report 14 August 2026, recommending the Bill be passed.
  • Senate: introduced and read a first time 12 August 2026, second reading moved the same day, second reading debate dated 17 August 2026.
  • Senate, concluded: second reading agreed 18 August 2026; in the Committee of the Whole, 32 government amendments agreed; third reading agreed 18 August 2026, all on the one day.
  • House of Representatives again: agreed to the Senate amendments 19 August 2026, and the Bill finally passed both Houses that day.
  • Assent: 20 August 2026. It is Act No. 66 of 2026, and the status on that page is now Assent.

So the Bill is finished and the contingency under every Bill-dependent date above is resolved. Two cautions remain. The dates in the government’s implementation sequence are still the government’s stated intent, not commencement provisions in the Act, and the two are not the same thing. And the Act itself commences in stages, one of which, the whistleblower protections the Senate added, does not start until 1 July 2027. What the Senate changed on its way through, and when each Part starts, is set out in our piece on the Act. We are still reporting the register rather than the room, and make no claim about what was said in the chamber.

How to read this calendar

Three different kinds of date are mixed here, and the difference is the practical point. The SIL dates are law in force now, with a penalty regime attached. The Thriving Kids dates are intergovernmental commitments with money attached, but the 2028 access change still needs an Act amendment. The Securing the NDIS dates are a stated implementation plan for a Bill that is now in the Senate itself. A provider planning workforce, audit schedules or service mix over the next 24 months is planning against all three levels of certainty at once, and the level matters as much as the date. We will keep this calendar current as instruments commence or dates move.
