New South Wales school staff will get extra training next year to help young people at risk of becoming radicalised.

Up to five specialist support teams will work with “identified schools” and respond to critical incidents, the NSW government has said.

The teams, which will cost about $15m, are part of measures aimed at countering violent extremism after the Parramatta terrorist attack which claimed the life of NSW police accountant Curtis Cheng.

“We are locked in a global struggle with cynical manipulators who exploit vulnerable young people and children to commit acts of terror,” the NSW premier, Mike Baird, said on Monday.

“I have always said we are much stronger united than divided and the measures announced today are designed to assist with precisely that.”

The state government will also provide $8m for a range of organisations committed to youth engagement, the programs involving high-profile community leaders.

Frontline NSW government workers, such as Family and Community Services officers, will also undergo training programs to counter violent extremism.

A support and advice telephone line, along with online services, will be set up for people needing advice on how to help young people who may be exposed to violent extremist influences.
