Authorities say they may be dealing with two hate crimes after offensive material was discovered at a family home and near a popular Adelaide beach.

At Camden Park in Adelaide’s western suburbs, a father told 7NEWS his family has been left shaken after their home was defaced with swastikas and antisemitic messages.

Police are now treating the graffiti as a suspected hate crime.

Rosti Sverdlov told 7NEWS he had just stepped outside to walk his dog when he discovered the graffiti plastered across his fence and front entry.

“After 7 October, we expect everything — but not to target myself, not to target my kids,” he said.

Police were called just before 7.40am on Saturday after reports of offensive material at the home. Officers found an offensive symbol, text and damage to a vehicle parked at the property.

CCTV from a neighbouring house shows a dark‑coloured sedan arriving at 4am, with two people approaching the property.

Sverdlov says they sprayed his doorbell camera before covering the fence in hate‑filled messages, then slashed the tyres of the family’s vehicles before driving off minutes later.

Sverdlov, a father of seven, says the attack targeted his family because of their faith.

“I never cover up the Jewish,” he said. “My kids, we grow up not to cover up our nationality. We’re proud of our nationality.”

Police say the motive remains unclear, but the use of the symbols “appears to be because the occupants are Jewish”.

They want to speak with the two people seen on CCTV and are urging anyone who knows them — or their associates — to come forward.

SAPOL is also investigating a second report of offensive material found near the Moana boat ramp at 9.30am on Sunday, but say the damage appears old and is not linked to the Camden Park incident.

Acting Assistant Commissioner Scott Fitzgerald condemned the graffiti.

“There is no place in South Australia for antisemitism, hatred or discrimination of any kind and we unequivocally condemn it,” he said

Fitzgerald also said that incidents like this can leave communities feeling targeted and vulnerable, and urged anyone who experiences criminal damage or harassment to report it immediately so police can investigate and build a broader picture of racism and discrimination in the community.

Neighbours have also voiced their disgust.

“Lovely man and a lovely family — and it just made me want to vomit, to be honest. I think it’s disgusting,” neighbour Joyce Chapman said.

Acting Premier Kyam Maher said he hopes those responsible are brought to justice.

“I very much hope that whoever did this is caught — and that they come down like a ton of bricks on whoever did this,” he said.

Sverdlov says the attack has left his family fearful but defiant.

“They could kill us,” he said. “I don’t know. But [a] message to them: I’m not afraid. I’m not afraid.”
