A wrap of the week: Appropriation Bills and the tax package in the House, the NDIS bill, the NACC resignation, and what Group A Estimates turned up in each committee.
Sitting for the House of Reps concluded for the week last night, but will be back again next week. Committees continue today however for Budget Estimates and public hearings (all in Canberra) for the:
Submissions also close today for the Parliamentary Joint Committee on the National Anti-Corruption Commission's inquiry into Aspects of the NACC's performance of its functions (aph.gov.au).
I've tried to make the summary of this week's events as succinct as possible without losing context (obviously important as we go into next week).
The Appropriation Bills (No. 1 and No. 2) 2026–27 (budget.gov.au) opened second reading debate Monday and consumed the chamber all week. Thursday brought the Treasury Laws Amendment (Tax Reform No. 1) Bill 2026 (aph.gov.au), introduced as a single bundle. It landed the same morning the ABS put headline inflation at 4.2%. The Opposition's "communist tax plan" frame now has fresh data to attach to it.
The NDIS Amendment (Securing the NDIS for Future Generations) Bill 2026 (aph.gov.au) drew sustained crossbench fire through its second reading debate. The Government conceded nothing. The Senate Community Affairs Legislation Committee's submission window closed Thursday; the bill now moves toward the Senate on the Government's current terms.
Paul Brereton's resignation as NACC (nacc.gov.au) Commissioner, announced Tuesday, ran as a second-order story in the chamber alongside Monday's disclosure of a foreign state cyber attack via WhatsApp on parliamentary accounts. Both land on a Government whose accountability record is already under pressure from the week's Estimates disclosures.
Next week the tax package becomes the central legislative contest. The Greens hold the Senate numbers the Government needs and have signalled they won't pass the bills unchanged. Whether the package survives committee in its current form, or gets renegotiated, will be the defining question of the sitting period.
NACC Commissioner Paul Brereton's appearance in a contested Tuesday hearing came ahead of NACC Inspector (nacc.gov.au) Gail Furness confirming a second investigation into Brereton's conduct is underway and declined to reveal its nature.
Home Affairs dominated the middle of the week. Secretary Stephanie Foster confirmed 6,634 Iranian nationals with fully valid visitor visas have had their travel to Australia frozen since March 2026, with only 480 exemptions approved from 752 appeals.
Senator Pocock's questioning on the $200,000 limited-tender contract (aph.gov.au) to a firm run by a former senior Morrison adviser bypassed open tender on "unique expertise" grounds sat alongside the Australia Institute's FOI release (australiainstitute.org.au) showing the Attorney-General's Department held back its FOI logs until one minute before February Estimates. Procurement transparency runs as a thread across the week's Home Affairs and AG questioning.
Thursday night's AFP and ASIO appearances crystallised the committee's most consequential unresolved question on the threat of terrorism in Australia: why their respective frameworks point in different directions.
The week opened with biodiversity, the circular economy and the Murray-Darling Basin Authority before shifting to the Budget's emissions and energy claims. DCCEEW (aph.gov.au) officials were pressed on Australia's headline figure — emissions up to 28% below 2005 levels — with scrutiny revealing the reduction relies almost entirely on contested land-clearing data under the decades-old "Australia clause." The integrity of Australia's emissions accounting baseline is now a live committee issue.
The Budget's $125 billion productive investment figure for the energy transition faced direct questioning on how much is genuinely new capital versus repackaged prior commitments, and whether the assumed 2:1 co-investment leverage ratio is defensible.
The eSafety Commissioner (esafety.gov.au)'s five-months-old age assurance scheme faced its first serious committee test Wednesday.
Australia's fuel reserve position ran as a cross-cutting theme across energy and communications hearings, connecting to the Strait of Hormuz closure. On both the emissions baseline and fuel security, the committee has drawn lines between Budget claims and the underlying data that the Government will need to answer before the appropriation bills clear the Senate.
The committee's opening days tested the fiscal architecture of the Budget itself: forward estimates, the discretionary trust minimum tax ($1.2 billion projected over four years), and the ANAO (anao.gov.au)'s own budget position.
The new APSC Commissioner appeared Wednesday. APS capability gaps, particularly AI governance readiness, were the focus with responses now being tracked by various news outlets.
The Budget's return-to-balance pathway rests on a single $37.8 billion assumption: NDIS expenditure growth falling from a historical average of 21% annually to 3% over the forward estimates. Senators pressed on whether any sensitivity analysis exists for growth tracking at 5%. No answer publicly resolved the question. That gap between the modelled assumption and any tested alternative scenario is the Budget's single largest unexamined risk.
The Future Fund (futurefund.gov.au)'s Thursday appearance brought the geopolitical thread into finance. The Fund's own modelling identified stagflation as its greatest vulnerability, and the Strait of Hormuz closure is now that scenario. The November 2024 mandate change - adding national priorities alongside returns - sits awkwardly against a risk environment the Fund itself predicted would be hardest to navigate. Whether the dual mandate is achievable under stagflation conditions was not answered.
The week opened with the regional and infrastructure spending envelope and fuel security - a cross-over issue that connected this committee's questioning to the Strait of Hormuz thread running through Finance and Environment hearings. The committee's role this week was testing the supply chain resilience assumptions behind several Budget lines simultaneously.
The ACIL Allen final report on Inland Rail (aph.gov.au) is now public. Senators used it to press the Government on cost and delivery figures for a project that has already blown well past its original budget. The report's public release removes the Government's ability to deflect on the numbers.
Thursday's hearings turned to the Strait of Hormuz and its downstream effect on globally traded fertiliser. The Hormuz closure covers 20–30% of global fertiliser transits; shipping through the strait collapsed from 103 vessels a day in late February to single digits within weeks. Agencies were tested on what that cascade means for Australian farm input costs.
Next week the tax package moves to the centre - the Greens' negotiating position, and whether the Government can hold the NDIS bill's terms in the Senate, will define whether this Budget's signature measures reach the statute book intact. Budget Estimates will turn to Group B: Community Affairs, Economics, Education and Employment (noting the Prime Minister's announcement (abc.net.au) two days ago on a significant overhaul to employment services), and Foreign Affairs, Defence and Trade.
See you in June!
