Machinery of government changes are one of those quietly consequential pieces of public administration that get a sentence in the press release and three years of operational pain in the affected agencies. The post-election MoG package announced in late 2025 was more substantial than most observers expected, and the implementation through Q1 2026 has produced the predictable mix of overdue rationalisation, awkward transitional arrangements, and a couple of decisions that look harder to defend with hindsight.

Worth running through the meaningful changes and where the friction is showing up.

The portfolio reshapes

The Department of Industry, Science and Resources was reorganised with the Critical Minerals Office moving formally under DISR after a period of effectively-shared arrangements with the Department of Climate Change, Energy, the Environment and Water. The administrative tidiness of that move is welcome, though the working relationships with DCCEEW on energy transition aspects of critical minerals will need to be carefully managed.

The Department of Home Affairs lost migration policy back to a re-established Department of Immigration and Multicultural Affairs in November, and the operational separation has been complex. The corporate services arrangements, IT systems, and detention-and-borders functions remained within Home Affairs, while the visa policy, citizenship, and settlement programs moved. Several SES officials I’ve spoken with describe the data-and-systems untangling as more difficult than the political sponsors anticipated.

The creation of a standalone Department of Skills and Workforce Development, lifting that function out of the Department of Employment and Workplace Relations, has been broadly well-received. The skills agenda has long been in tension with the workplace relations and employment services agendas inside the same department, and giving it dedicated departmental focus is defensible.

The Australian Public Service Commission picked up additional remit on integrity and ethics frameworks, building on the post-Robodebt institutional reforms. That’s a useful consolidation but stretches APSC capacity in ways that will need resourcing follow-through.

What didn’t move that probably should have

The persistent question of whether the Australian Bureau of Statistics should sit under Treasury or move to a more independent statutory arrangement was not addressed in this MoG round. The structural argument for a more independent ABS has been made repeatedly — the OECD has commented on it, several productivity reviews have noted it. The political appetite for the change wasn’t there, and the opportunity has now passed for this term.

The various climate-and-environment functions across DCCEEW, the Department of Agriculture, Fisheries and Forestry, and DISR remain split in ways that produce real coordination overhead. A more thorough rationalisation was floated and didn’t make the final package, partly for ministerial-allocation reasons.

Implementation friction — the operational picture

The corporate services consolidation aspects of MoG changes are always where the practical pain lands. The ICT systems separation between Home Affairs and the new Immigration department is the highest-stakes example. Visa case management, identity matching, and biometric processing systems span functions that have now been split across departmental boundaries. The data-sharing arrangements need formal authorisation under the Data Sharing Act framework, which adds compliance overhead.

The financial management systems separation is similarly complex. Payment processing, budget allocations, asset transfers all have to be sequenced through end-of-financial-year cycles, which is why MoG changes announced after October typically don’t fully bed down operationally until at least the second financial year after the change.

The staffing transitions involve about 4,200 employees across the most-affected departments, with the bulk of those in Home Affairs/DIMA and DEWR/Skills. The APS Commission’s MoG transition guidance has been workmanlike but the agency-level implementation has varied. AAP reported in late March that several SES officials had taken voluntary redundancy rather than accept the new departmental arrangements, which is a recurring pattern in MoG changes.

The strategic policy capacity question

One concern worth flagging is the strategic policy capacity gap that often opens during MoG transitions. Senior policy staff are absorbed in transitional arrangements, governance redesign, and organisational rebuilding rather than substantive policy development. The 12–18 month period after a major MoG change typically produces less ambitious policy output from affected portfolios.

For the new Immigration department in particular, this is a real concern. Migration policy reform has been a slow-moving priority area, and the departmental rebuild risks producing another year of incremental rather than substantive policy work. The ministerial leadership matters here — clear policy direction can compress the transition period meaningfully.

The agency-design lessons

A few patterns from this MoG round that policy analysts should track:

Departmental separations work better when corporate services arrangements are clean from the start. The shared services experiments of the 2010s produced complex unwinding work in subsequent MoG events. The newer departments are mostly being set up with discrete corporate services from inception, which is more expensive but operationally cleaner.

ICT system entanglement is the highest-risk implementation friction. The lesson from Home Affairs/DIMA, and from previous MoG events, is that system architecture needs to be considered explicitly at the policy decision stage, not deferred to implementation. The DTA could play a stronger role here than it currently does.

The grants administration functions have, again, been split inelegantly. Several smaller grant programs moved between portfolios in this MoG round in ways that are creating overhead for grant recipients and the implementing teams. Grants administration reform — across the APS — remains an unfinished agenda from the post-Robodebt reform period.

What I’d watch through the next 12 months

The DIMA stand-up reaches its first full operating year in November 2026. The performance metrics — visa processing times, complaints, integrity outcomes — will be the proximate test of whether the separation has delivered the policy outcomes that justified it. The Department of Home Affairs, with reduced scope, will face its own questions about whether the lighter remit allows better focus on the borders and security functions that remain.

The Skills and Workforce Development department’s first major policy product will be the response to the Jobs and Skills Australia workforce planning recommendations due mid-year. Whether the new department produces a sharper response than the old DEWR arrangement would have is the substantive test.

Machinery of government changes are a tool. They’re not policy. The substantive outcomes depend on whether the new arrangements enable better policy work and better service delivery than the old ones — and that’s a question we won’t be able to answer properly for at least another 18 months.
