Two ACT government directorates are searching for new director-generals, amid a wider shakeup at the top of the territory's public service.
The government's Community Services directorate is looking for a permanent replacement for Michael De'Ath, who has been heading up ACT Health for more than a year.
Rebecca Cross has been acting as interim head of community services, which has oversight of public housing, child support and disabilities.
The territory's education directorate is also searching for a new director-general following the retirement of Natalie Howson in late May.
The most senior posts in each of the territory's seven directorates command an annual base salary of $350,025.
The search for new heads at the two directorates comes as the arrival of the ACT's new infrastructure delivery agency is set to trigger a flurry of movement within the territory's public service.
Transport Canberra will need to find a replacement for Duncan Edgill, who will act as the interim head of Major Projects Canberra.
About 140 staff working in the infrastructure branches of Transport Canberra, Health and Treasury will be shifted into the new agency as part of the restructure.
The announcement of the new agency drew widespread attention earlier this week, as parallels were drawn between it and the fictional government department depicted the ABC satire Utopia.
Opposition leader Alistair Coe questioned the purpose of the agency, arguing various government departments were already delivering infrastructure.
Appearing before budget estimates hearings on Tuesday, Chief Minister Andrew Barr seemingly added weight to that argument, saying the creation of the new agency was "unremarkable" and would represent only an "incremental change in that way we will deliver our infrastructure program".
Mr Barr said discussions about creating an infrastructure delivery agency has been ongoing for some months, but a final decision had only been made in the past week - just days after he handed down the 2019-20 budget.
He said the decision did not require, nor did it receive, cabinet approval.
In other movements within the territory bureaucracy, Access Canberra boss Dave Peffer has been seconded to ACT Health to fill the position of deputy director-general of health systems, policy and research.
David Snowden, Access Canberra's chief operating office, will step into up to lead the agency in Mr Peffer's absence.
An Access Canberra spokeswoman said the ACT Public Service supported executives moving between different directorates.
