He attacked political correctness and said gay people are joked about because they are loved Mr Latham was one of two One Nation MPs elected to the NSW Parliament in March

Addressing the upper house for the first time, he praised the state's early colonialists and criticised "leftist elites" for what he said was an attack on western civilisation.

"It's like a scene from The Life of Brian," he said.

"What has Western civilisation done for us?

"Only advanced healthcare and education, architecture, engineering, information technology, free speech and the rule of law."

Mr Latham even compared the left to the characters in political satirist George Orwell's novel Animal Farm.

"In their lust for authority, they lose their respect for the rights of others," he said.

"Like a scene from Orwell's Animal Farm, the Green-Labor-Left has become the thing it originally opposed: elitist, would-be dictators taking away from the working-class communities the things these battlers value."

He also attacked political correctness and the "confected outrage" of the "elites".

Quoting Monty Python actor John Cleese, Mr Latham argued that telling a joke about someone does not mean you hate them.

"We love the people we joke about — the Irish, the blondes, the gays, everyone — as they've helped to bring humour and joy into our lives."

He also used his inaugural speech to call for laws protecting freedom of speech and religious freedoms and to pledge his support for rugby player Israel Folau.

The Wallabies star is facing a possible contract termination after he made comments denouncing homosexuality on Instagram.

"I stand with Israel Folau … he believes, as millions of people have believed for thousands of years, that sinners go to hell," Mr Latham said.

"Yet for his beliefs, his Christianity, he is not allowed to play rugby, to chase the pigskin around the park.

"How did our State and our nation ever come to this?"

The One Nation MP spoke for more than 47 minutes, calling for limits on immigration, an end to identity politics, an overhaul of the state's education system and the introduction of nuclear power and greater investment in coal-fired power.

He is one of two One Nation MPs elected to the upper house who hold the balance of power with nine other crossbenchers.
