NSW Health will receive an extra $700 million to boost a range of services including doubling the capacity of intensive care units across the state, preparing for additional coronavirus testing and buying extra ventilators and medical equipment.

Premier Gladys Berejiklian said the remaining $1.6 billion was dedicated to much-anticipated economic stimulus measures, designed to keep people in jobs throughout the crisis.

"Our first priority is always the health of the people of this state and looking after their families and jobs," Ms Berejiklian said.

As part of the measures, $450 million has been allocated to waive payroll tax for businesses with payrolls of up to $10 million for three months.

The State Government said these businesses would not have to pay the tax for the rest of this financial year.

The next round of payroll tax cuts has also been brought forward to raise the threshold limit to $1 million for the next financial year.

There is also $80 million for fees and charges to be waived for small businesses such as cafes, restaurants and those in trades, as well as $250 million for public schools and state-owned buildings to employ more cleaners.

"The Government stands ready to do whatever it takes to keep people safe and ensure our economy withstands this storm," Treasurer Dominic Perrottet said.

The Treasurer is also drawing on the state infrastructure as part of his plan to stimulate the economy.

More than $750 million will be spent on capital works and maintenance of public assets.

The State Government has been under pressure to release this package.

The State Opposition has accused the Government of being slow to act as the Federal Government and other states, including Western Australia and Queensland, have already unveiled their packages.
