Australian police have released CCTV images after 'offensive graffiti' was sprayed on a synagogue and a house in Sydney city, showcasing yet another instance when the country's Jewish community was targeted.

According to reports, vandals targeted a synagogue and spray-painted red swastikas outside its entrance.

New South Wales Police said its officers attached to Inner West Police Area Command were notified after graffiti was spray painted on a synagogue on Georgina Street, Newtown.

"Initial inquiries have led police to believe two people attended the synagogue around 4.25am today and spray painted graffiti on the fence and building, while also attempting to light the premises on fire," police said in a statement.

Police said the pair left the scene afterwards.

"A crime scene was established and investigations into the circumstances surrounding the incident commenced," police said.

Police said they are also investigating two other separate incidents of graffiti in Sydney.

"Officers from Eastern Suburbs Police Area Command were notified about 6.30am after graffiti was spray painted on a house on Henry Street, Queens Park, as well as five parked and unattended cars and a trailer on the same street," read the police statement.

New South Wales Premier Chris Minns described the incidents as 'horrifying' and 'hateful'.
