Nazi chants banned in push to stop 'vile hatred'

Though Nazi symbols are already banned in many jurisdictions, the bill will expand the ban to behaviour that shows support for Nazi ideology through imagery or characteristics associated with the ideology.

Anyone who repeats Nazi chants will face up to a year in prison or a maximum fine of $11,000 - a punishment that could be doubled for those  who do so near a synagogue, Jewish school or the Sydney Jewish Museum.

"The deplorable stunt we saw outside NSW parliament has no place in our society," NSW Attorney-General Michael Daley said.

"Nobody should be subject to this vile hatred because of their background or faith.

"We are giving police and the courts additional powers to hold Nazi extremists to account for their abhorrent views."

Police will be able to order perpetrators to take down suspected Nazi symbols and those who refuse could be hit with a $2200 fine or three months' prison.

Neo-Nazis, who often don face coverings and sunglasses in public, will find it harder to hide as police are given powers to order people to reveal their identity if it helps an investigation for a Nazi-related offence.

The new legislation was announced a day after the NSW government introduced a bill renewing a controversial push to stop protests near synagogues, despite being struck down by the courts for being too broad.

It would allow police to move on protesters who affect a person's ability to enter or leave a place of worship.

The federal government has also taken action in the aftermath of the demonstration, revoking the visa of a South African neo-Nazi who attended the rally.

Matthew Gruter was taken into detention on Tuesday to await his imminent deportation, Home Affairs Minister Tony Burke revealed.

Though the move has been supported by members of the coalition and One Nation, United Australia Party senator Ralph Babet defended Gruter's right to free speech, warning "eventually the same power and attitude will be turned against you for your views".
