Corrections Minister Geoff Lee, who is retiring at the March poll, is scheduled first-up on Monday after an August hearing for the portfolio was postponed.
Mr Lee could face questions about why the United Nations subcommittee on torture prevention has been denied access to the state's prisons.
Premier Dominic Perrottet told parliament last week there were already "significant oversight processes" in place.
"We've set up those oversights in our prison system and if people have issues ... you can raise them with the minister or the corrective services commissioner," Mr Perrottet said.
Members of the Regional NSW and Stronger Communities portfolio committee could take the premier's advice when Mr Lee fronts up on Monday.
He may also be asked about Clarence Correctional Centre, Australia's largest prison on the Northern Rivers near Grafton, where officers have gone on strike twice in the past month in protest over pay and staff levels.
Education and Early Learning Minister Sarah Mitchell will face a hearing on Tuesday.
She will likely be asked further questions about the government's plans and progress to recruit more teachers by the two Labor members of that committee, as the party prepares to make it an election issue.
There will be no shortage of questions for Transport Minister David Elliott on Wednesday morning.
His portfolio is beset by industrial disharmony on the railways, as well as procurement issues with cracked trams, shoddy ferries, and a transition to electric buses that Mr Elliott told his last estimates hearing won't hit a target set by former minister Andrew Constance.
"There's no way in the world we're going to meet that timetable, so I don't know why (Mr Constance) said it," Mr Elliott told his previous hearing.
On Wednesday, Metropolitan Roads Minister Natalie Ward is likely to face questioning about Sydney's toll road network, which is another election issue.
Ms Ward and Regional Transport and Roads Minister Sam Farraway could also be asked about flood-damaged roads across the state and the potential cost of fixing them.
Mr Farraway may also be questioned about a Korean-built fleet of intercity trains that have been sitting in storage since 2019 while the Rail, Tram and Bus Union calls for them to be modified.
The modifications, which the government insists are unnecessary, are an element of the industrial disharmony facing Mr Elliott's transport portfolio.
Unions are also seeking a new enterprise agreement after the existing one expired in May 2021.
Infrastructure, Cities and Active Transport Minister Rob Stokes is also retiring in March, but will close out Wednesday's hearings.
Health Minister Brad Hazzard is yet to reveal whether he will seek to extend his more than three-decade parliamentary career by another four years in March, but is scheduled to appear on Thursday afternoon.
