A man has been caught on video making "vile" anti-Semitic remarks to a rabbi during a road rage incident in Melbourne in what a Jewish anti-hate group says is one in a series of similar outbursts against Jews in Australia.

Key points: The Anti Defamation Commission says it is seeing a rise in anti-Semitism

The Anti Defamation Commission says it is seeing a rise in anti-Semitism In a separate case in Elsternwick, a woman was reportedly told: "Hitler was right, he should have killed you"

In a separate case in Elsternwick, a woman was reportedly told: "Hitler was right, he should have killed you" Earlier this month demonstrators at a far-right rally were seen making Nazi salutes

From the passenger seat of a car waiting at traffic lights on North Road in Caulfield, in the city's south-east, the man can be heard saying: "Would you like me to get out and show you what Hitler did?"

The man then called the rabbi a "f**king selfish c***t of a Jew".

The female driver could also be seen making gestures at the rabbi's car.

The Anti Defamation Commission (ADC), which posted the exchange on its Facebook page, condemned the remarks.

ADC chair Dr Dvir Abramovich said the comments were "vile and repugnant anti-Semitic slurs".

He said there had been a significant increase in reports of anti-Semitism in the last 12 months.

"Anti-Semitism in our nation is alive and well and we should all be deeply concerned about this stain on our society," Dr Abramovich told ABC Radio Melbourne.

"There's a troubling picture emerging over the last 12 months.

"Even for someone like myself, who is involved in fighting anti-Semitism 24/7, the last 12 months have shocked me to the core."

Dr Abramovich said in a similar incident, a woman was shouted at while driving in Elsternwick by another driver who said: "Hitler was right, he should have killed you".

"We had a teacher in a supermarket car park in Bentleigh subjected to an appalling racist tirade, with a woman and a man yelling: 'Hitler had the right idea'."

"A 13-year-old Jewish girl at a public school was sent a snapchat video with a classmate rapping about her going to the gas showers.

"So this is something we're seeing more and more. It's quite scary."

Sorry, this video has expired Neo-Nazis appeared at a protest at Melbourne's St Kilda beach in January.

Earlier this month some demonstrators at a rally organised by the far-right at St Kilda beach carried Nazi insignia and made Nazi salutes.

Dr Abramovich said it was difficult to point to one reason for the apparent rise in anti-Semitism.

"We are living in a particularly toxic time when we are seeing an increase in xenophobia, in racism, which is often stoked by the rhetoric of some public figures," he said.
