NSW Premier Chris Minns said a string of fresh antisemitic incidents including graffiti sprayed on a Jewish school and a residential property next to it in Sydney's Maroubra are "antithetical against everything Australia believes" and said counter-terrorism police have been deployed.
Police said on Thursday there were three separate antisemitic graffiti incidents in Sydney's eastern suburbs overnight — in Maroubra, Eastgardens and Eastlakes.
Speaking on the Maroubra incident as students were supposed to return for their first day of the school year, Minns said it was: "utterly appalling and shameful that an individual would spray racist hate-filled messages on a school".
"It tells you everything you need to know about how appalling these bastards are that they would rip apart a school on one of the first days of school with a racist antisemitic attack."

"I'm ashamed to say it — but that's the truth. Bad morals, bad ethics, bad people that will commit these acts but Australians stand united against this appalling racism."
The NSW Jewish Board of Deputies called the vandalism "grotesque" and "sickening".
"Children will be forced to walk past this repellent hate speech as they make their way back to school," it said in a statement.
It comes as the premier filled with explosives and antisemitic notes had been found in Dural.

"Send a clear and unambiguous message that Australians will not stand for this kind of violent hate-filled racist attack in Australia in 2025", Minns said.
He said that in the past two weeks, 10 people had been arrested for malicious damage, fire damage and graffiti attacks in NSW.
