The incident comes after a spate of antisemitic attacks in Sydney, with a childcare centre near a synagogue in the city's east set alight and sprayed with antisemitic graffiti on 21 January.
Arrests had been made "around the periphery", with some connected to other alleged anti-Semitic attacks, but those responsible remain at large, NSW Police Deputy Commissioner David Hudson said.
A trailer packed with explosives and a list of apparent Jewish targets was found hidden in an Australian suburb last week, police revealed Wednesday — calling it a thwarted antisemitic terrorism attack.
