NSW Premier and the Nazi costume

NSW Premier Dominic Perrottet (right) will be referred to the police by the NSW Shooters, Fishers and Farmers Party, Robert Borsak that wants to know if he breached an obscure law on declarations when he joined the Liberal party in the wake of his Nazi costume controversy

The premier potentially broke the Oaths Act when he signed a Liberal Party preselection document around 2010 and declared he had nothing to disclose that could embarrass the party.

A person found to have breached the Oaths Act could face up to five years jail Mr Perrottet, 40, was asked if any other future-Liberal politicians were at his 21st party at his par- ents' home in Sydney's northwest He said he couldn't recall who was there and did not want to "drag" others into it "It's not about other people, I made a mistake; it's about what I did," he told reporters

Attorney-General Mark Dreyfus, who is of Jewish ancestry, told SBS News it was up to Mr Perrottet to explain his actions "Dressing up as a Nazi is not a joke But clearly, I'm able to say that I welcome his expressions of regret," said Mr Dreyfus, after speaking at a Holocaust memorial event in Melbourne

NSW Treasurer and deputy Liberal leader, Matt Kean said he wouldn't challenge the premier and the government was ready to move on from the scandal

Meanwhile The Victorian government is considering expanding the list of banned Nazi hate symbols in the state after a prominent neo-Nazi made an offensive gesture outside court

Thomas Sewell, the 29-year-old leader of the European Australian Movement made a Nazi salute after speaking to the media last week outside the Melbourne Magistrates Court, where he avoided time behind bars over a brutal attack on a Nine Network security guard.

It's been illegal to publicly display Nazi symbols in Victoria since 29 December, when laws prohibiting the display of the Hakenkreuz, often referred to as the Nazi swastika, came into effect. People found flouting the law face a fine of approximately $22,000 or 12 months imprisonment
