Consultation for the review, which is being led by Independent Reviewer Ian Watt, is now open and submissions close on October 9, 2020.

An initial report is due in October and a final report is expected by the end of March 2021.

Community and Public Sector Union general secretary Tom Lynch said he would be meeting with Dr Watt on Friday and would be raising the union's concern about the timeline with him.

"Reviews like this other states have taken years and have been rolled out in stages whereas this will be calling for submissions, closing them on the 9^th of October and a report will be provided to the Premier in October," Mr Lynch said.

"I don't understand what the urgency is to get the first report to the Premier within four weeks.

"I would have thought it was far more important to address the significant issues that have been set out in the terms of reference.

"Rushing this seems to be a regular way of doing things with this government."

Labor finance spokesman David O'Byrne urged the government to not cut jobs and services as part of the review.

"The review terms of reference refer to efficiencies, improvements, and streamlining - in the past this has been used as classic code for privatisation and job cuts," Mr O'Byrne said.

"There is nothing wrong with a review of the state service to ensure it is undertaking best practice, but at such an unprecedented time in the state's history, it must not lead to the loss of vital Tasmanian jobs or diminishing the quality of services."

Premier Peter Gutwein said the review aimed to identify structural, operational, service, practice and legislative improvements to ensure the public service was in the best shape to deliver the services Tasmania needed.

"I have categorically ruled out job cuts in the public sector as recently as the last parliamentary sitting," he said.

"The government wants to ensure the service is best placed to serve Tasmanians today and into the future, and encourages submissions being made to the review."

Submissions to the review can be made via email to StateServiceReview@dpac.tas.gov.au or via mail to GPO Box 123, Hobart, TAS, 7001.
