A newly elected Australian senator has used his maiden speech in Parliament to call for an "OzExit" from the United Nations.

"Australia's values and way of life are also at risk from insidious institutions such as the unelected swill that is the United Nations," Malcolm Roberts, a representative of the anti-immigration One Nation party, said Tuesday of the intergovernmental organization of which Australia was a founding member in 1945.

"The E.U. is a template for total socialist domination of Europe through unelected bodies, such as the IMF, forcing their frightening agenda on the people," Roberts went on to say, referring to the European Union and the International Monetary Fund. "It is also the U.N.'s template, and Australia must leave the U.N."

"We need an OzExit," he said, referencing Britain's recent Brexit vote to leave the E.U.

The comment drew little visible reaction from the mostly empty Parliament.

The rest of Roberts's 20-minute speech focused largely on climate change denial and criticism of the global banking system. "It is basic. The sun warms the Earth's surface," he said at one point. "The surface, by contact, warms the moving, circulating atmosphere. That means the atmosphere cools the surface. How then can the atmosphere warm it? It cannot. That is why their computer models are wrong."

Roberts assumed office on July 2. According to News Corp Australia, he had not held paid employment for eight years before that day.

Instead, he was the leader of the Galileo Movement, a climate-change-denial group. In 2012, he told the Sydney Morning Herald that climate-change science was being controlled by "some of the major banking families in the world" who form a "tightknit cabal." Fellow skeptics later suggested that Roberts erred worryingly close to "the Jewish world conspiracy theorizing."

The One Nation party, which Roberts represents, is led by Pauline Hanson. Hanson, 62, won a seat in Parliament as an independent in 1996 after she was expelled from the Liberal Party for questioning the state benefits given to aboriginals. She later set up One Nation, renewing focus on the Asian immigration to Australia.

Hanson lost her seat in 1998, and One Nation spent almost two decades in the political wilderness. However, a resurgent One Nation had four candidates (including Hanson) elected to the Senate in July — enough to make the party a potentially powerful force when the ruling Liberal-National coalition lacks a majority.

One Nation's message has lately shifted to include a strong anti-Islam message. In her speech to Parliament on Wednesday, Hanson warned that Australia was "in danger of being swamped by Muslims" and called for an end to all immigration. A number of senators from the Green Party walked out during her speech.

Hanson was widely noted to have rolled her eyes at one point during Roberts's speech, though she later released a statement saying she was "simply embarrassed" by his effusive praise for her.
