Nuclear protesters in hazmat suits heckle Peter Dutton before they're evicted from NSW Liberal Party conference in Sydney

Protesters dressed in replica hazmat suits were evicted from the NSW Liberal Conference on Saturday after heckling Opposition Leader Peter Dutton about his stance on nuclear energy.

Liberal Party members and supporters watched on as a group of men entered the conference lobby in Sydney, claiming to be Mr Dutton.

A video uploaded to the South Coast Labour Council Facebook page showed two men dressed in white full-body suits with radiation hazard symbols and signs reading 'Dutton MP for Fukushima' and 'Nukes 'R' Us'.

'We have a special announcement from the leader of the opposition, Member for Fukushima, Peter Dutton,' one protester said about the disruption.

Disgruntled members off camera could be heard yelling 'p*** off' to the group of men as they continued their performance.

'I'm sorry we haven't supported Save the Whales before, but we are going to save the whales from those pesky wind farms downstairs,' a protester pretending to be Mr Dutton said.

The men spent minutes declaring their support for nuclear energy and opposition to a ceasefire in the Israel-Palestine conflict before they were escorted out of the conference chanting 'Nukes 'R' Us, Nukes 'R' Us.'

Following the protest, Mr Dutton took to the podium to outline his plan to 'start a conversation' about nuclear energy in Australia.

He said most Australians didn't understand the basics of nuclear energy, which he argued could greatly benefit Australia if implemented correctly.

'Most people were influenced by the incidence of Chernobyl and elsewhere, some people in the research were influenced by The Simpsons,' the Opposition Leader said.

'If you've watched The Simpsons, some of the research work demonstrated that people didn't want a Springfield going up in their backyard.'

Mr Dutton was critical of the government's recent energy schemes, saying the Australian taxpayer will be 'on the hook for years' as a result of mismanagement.

Earlier in the conference tensions appeared to linger from the recent Voice referendum when NSW Liberal state executive member Michelle Bishop was booed while acknowledging the traditional owners of the land. 

Ms Bishop addressed the crowd of 600 at the Fullerton Hotel where she acknowledged 'that we are on the land of the Gadigal people of the Eora Nation and acknowledge our traditional owners'.

Members of the audience began jeering Ms Bishop as she nervously stammered through her short speech. 

One member said that it was just a small clump of the crowd that was behind the booing and that not everyone joined in.
