A woman at a pro-refugee rally has told a former Israeli soldier she would refuse to speak with him because he is Jewish.

Conservative activist Avi Yemini was in Melbourne, wearing a yarmulke and interviewing people on the plight of white South African farmers, when he encountered the anti-Semitic remarks by a woman.

'You’re Jewish, right. You’re Jewish, forget it,' she told him.

Earlier, she had denied white farmers in South Africa were being targeted with violence, despite 400 such landowners being murdered in 2017 alone and before parliament voted last month to seize their land without compensation.

'Yes, I'm denying it,' she said.

Yemini, a former Israeli soldier who this month joined the right-wing Australian Liberty Alliance, encountered some hostility at the Bourke Street mall in the city as he vox-popped protesters at Justice for Refugees rally on Sunday.

'Drop dead, you're a fascist. Drop dead, you're a fascist,' one man shouted.

Another man physically jostled with the former soldier and gym owner as he asked him about South African farmers.

'I don't want to talk to you man because you're a f***er,' he said, before grabbing his arm. 'Go away, don't threaten me.'

Despite being clearly identified as Jewish, Yemini was asked by one woman if he was associated with Nazis.

'Why are you hanging out with your Nazi mate over there?,' she asked.

On the issue of refugees, another woman slammed Immigration Minister Peter Dutton for wanting to give special visas to white South African farmers when he should be helping Muslim Rohingya refugees in Myanmar instead.

'He's a racist and a fascist and a murderer,' she said.

'That's Peter Dutton, sums (it) up for me.'

Although there is no suggestion Mr Dutton actually is a murderer, when asked how he could be one, the woman said he was 'allowing them to die' in Myanmar.
