Keira MP Ryan Park holds "massive concerns" Wollongong public service workers will be targeted when the government slashes 2500 jobs in the state.
Premier Gladys Berejiklian claimed that front line public sector workers and public service jobs in regional areas would not be affected by the cuts announced in the budget on Tuesday.
The opposition treasurer said he was hearing that Wollongong, Newcastle and Sydney workers would be the focus of the cuts.
"There is already unemployment concerns in our region," he said. "Illawarra workers help to provide many government services.
"I don't want to see them lose their job, put extra pressure on the public sector and diminish the service provided to the community."
At a budget press conference, treasurer Dominic Perrottet downplayed the job cuts when he said "only about one per cent" of workers would lose their jobs and the government was investing in 4,600 teachers, 5,000 nurses and midwives, 3,300 more health professionals and 1,500 police.
"Mr Perrottet should talk to all 2500 workers and their families to see if their sacking is a big deal and ask them how they are going to afford to pay for their mortgage, put food on the table and pay school and health fees," he said.
"The cuts will affect thousands and I am concerned our region will be targeted and that will have an impact on our community members and the delivery of services."
Mr Park said front line public servants like teachers, nurses, social workers, and emergency services personnel rely on the support of their back office colleagues across the rest of the public service so they can provide the important services that the NSW public rely upon.
"The sackings mean the jobs of front line public servants will only get harder, and the people of NSW will be worse off with lower quality public services," he said.
"I don't want to see nurses, teachers and police loaded up with administration tasks because that is not what the community expects or deserves."
No details have been released as to which departments or types of jobs would be cut.
South Coast Labour Council Secretary Arthur Rorris said the government should have taken its proposal to slash jobs to the election.
"When it comes to sharing the pain, we are part of the Sydney empire and cop the job cuts. When it comes to upgrades in rail, hospitals and stadiums we are out in the sticks - not even on the map. We get nothing.
"We can't even get a lift on a train station down here. Let alone a rail line that moves people faster than the old steam trains."
"The excuses for job cuts being back room and not front line have become rather stale.
Every support job that goes means taking away a nurse, firefighter, paramedic, cop or teacher from their daily duties to make up the shortfall.
"There is no front and back here. Public services need all hands on deck."
Mr Park said he was disappointed the government had decided to cut jobs given he with his Illawarra Labor MP colleagues had an election policy to move the Liquor and Gaming department to the Illawarra to boost jobs in the region and stimulate the economy.
"This government does not support regional areas and the budget emphasises that," he said.
