A man has been shot dead after turning a gun on police on a rural property on the NSW Central Coast, with police hunting another man.
Nearby Warnervale Public School is in lockdown after the shooting on Thursday morning and police are warning the public to stay inside as a second man - who is potentially armed - is believed to be on the run.
Police said officers tracked a stolen Land Cruiser with two men inside to a semi-rural property in the Wyong area shortly after 9am following an earlier pursuit that was abandoned.
Police lost sight of the stolen vehicle after it rammed another car but it was tracked to the property where police found a man trying to break into a garage.
One of the two men then threatened the officers with a firearm and was shot.
Assistant Commissioner Max Mitchell praised police for their courage and professionalism.
"Having a double-barrelled firearm pointed at you. Fear of life - there can be no more strenuous position for a police officer to be placed in," Mr Mitchell told reporters in Wyong.
"They have my full support."
Police have not yet identified the man who died at the scene.
They have extensive resources involved in the hunt for the wanted man with local police supported by multiple specialists including Tactical Operations support officers and Polair.
"These are experts and the community is safe," Mr Mitchell said.
An investigation has been launched and a report will be prepared for the NSW Coroner.
