New figures show the despite big cuts, there are now more public servants than ever.

The state’s Liberal government has cut over 800 full-time positions since it came to power in 2014, but a new State Service Annual Report shows the numbers have crept back up.

There are now 23,004 full time equivalent staff (FTEs) in the public service, an increase on the 2014 figure of 22,480.

Unions Tasmania says the figures show the Liberals’ cuts were not needed, and short-sighted.

The Labor opposition says taxpayers had paid out millions in redundancies for no reason.

But Treasurer Peter Gutwein says the cuts were necessary.

He said they had made room for more investment on the frontline, including 350 more staff to support the state's ailing health system.

“What we've done is we've cut from the backline and invested in the frontline,” he said.

“We now have more doctors, more nurses, more allied health professionals, there are more teachers in our schools.

“We have been able to make savings in the backline and strengthen the frontline.”

The Government says it does not intend “to further reduce the size of the public sector in the foreseeable future”.
