Malcolm Roberts

Roberts believes that the United Nations is a threat to the Australian way of life: "Australian values and way of life are also at risk from insidious institutions such as the unelected swill that is the United Nations. Australia must leave the UN. We need an OzExit." He states that the UN is "destroying Australia’s sovereignty through deals such as Agenda 21".

In September 2017, before the High Court ruling on Roberts's eligibility, blogger Tony Magrathea intiated a High Court action alleging that Roberts had sat in the Senate while disqualified, contrary to the Common Informers (Parliamentary Disqualifications) Act 1975. On 24 June 2019, the High Court found the allegation proved and ordered Roberts to pay a penalty of $6,000 to Magrathea.

With his citizenship clear, Roberts was elected to the Senate again in 2019.

Following the 2017 resignations of Scott Ludlam and Larissa Waters due to dual citizenship and Matt Canavan's resignation from the Cabinet for similar reasons, Roberts' place of birth and citizenship was scrutinised by the media. Roberts released a statutory declaration to the effect that he is only an Australian citizen, despite birth records showing that he had previously been identified as a British national. A spokesperson for Roberts stated that Roberts was "choosing to believe that he was never British". Doubts persisted about the status of Roberts' Indian citizenship after it was argued in the media that under a precedent set by the Supreme Court of India, he continued to be a 'presumed citizen' of the country.

On 9 August 2017 the Senate referred his position to the High Court as Court of Disputed Returns. The reference was moved by his party leader Pauline Hanson, with his support. On 22 September 2017, the High Court of Australia found that Roberts was a citizen of the United Kingdom, through descent from his Welsh father, when he was elected at the 2016 federal election. His suitability for retaining his Senate seat depended on whether he had taken appropriate steps to renounce his British citizenship prior to his nomination. Between August and October 2017, Roberts stated several changing and contradictory positions regarding his citizenship, including that he had "absolute conviction" of being an Australian upon nomination, that he had emailed British authorities on 1 May 2016, first requesting to renounce his citizenship, and upon receiving no reply for a month, sent a subsequent email on 6 June (three days after his nomination) stating, "As there was no reply to my email last month (see below) and although I am confident I am not a British citizen, with this email I renounce any British citizenship should it exist." It was subsequently revealed that the email domains that Roberts had contacted were defunct and no longer in use. Roberts sent a formal application to renounce his United Kingdom citizenship on 2 November 2016, and his renouncement became official on 5 December 2016.

A final decision regarding Roberts's senatorial eligibility was scheduled to be heard by the High Court, as the Court of Disputed Returns, between 10 and 12 October 2017. However, the Court delegated the fact-finding task to a single judge, Justice Keane, before whom Roberts appeared on 21 September and who reported his findings on the following day.

On 27 October 2017 the full High Court, as the Court of Disputed Returns, ruled that Roberts had been ineligible to be elected to the Parliament. Roberts and One Nation leader Pauline Hanson subsequently announced that Roberts would nominate as a candidate for the electoral district of Ipswich at the next Queensland state election. He was not elected. In February 2018, it was announced that Roberts would lead the One Nation Senate ticket in Queensland at the 2019 Australian federal election. Pauline Hanson said: "Malcolm Roberts has got the reputation as a powerhouse, the empirical science man, and he's really taken it up to members of parliament".

Roberts was elected to the Senate at the 2016 Australian federal election, running in second place on One Nation's ticket in Queensland, behind party leader Pauline Hanson. However, he was subsequently found to be ineligible for election. He received 77 first-preference votes in that election, the lowest number ever for a member of the federal parliament.

Roberts frequently states that NASA has falsified climate data to exaggerate warming in the Arctic. In November 2016, Gavin Schmidt, director of NASA's Goddard Institute for Space Studies, told Roberts he was "mistaken" to assert NASA had removed data to hide Arctic warming in the 1940s. Schmidt stated that the data was freely available online and that Roberts should check it himself, adding that he was surprised that Roberts was in fact a senator, and that his allegation of inappropriate temperature data adjustment is "the definition of denial".

In 2016, Roberts requested a briefing from the Commonwealth Scientific and Industrial Research Organisation (CSIRO) on scientific evidence of human-caused global warming. The briefing was delivered in September 2016, after which Roberts said he would consider the CSIRO's evidence, but also accused the CSIRO of pushing the "de-industrialisation" of Australia, and added that policies to mitigate climate change were "anti-human".

On 6 November 2016 Roberts delivered his response to the briefing, presenting a 42-page report titled "On Climate, CSIRO Lacks Empirical Proof", co-authored by Timothy Ball and Tony Heller.

In a clash between Roberts and physicist Brian Cox on the live television talk show Q&A on ABC TV broadcast 15 August 2016, Roberts claimed that engineer and blogger Steven Goddard (a pseudonym of Tony Heller) had shown the NASA temperature data for the 1930s were "warmer than recent decades". In The Guardian's assessment, Roberts was referring to a debunked conspiracy theory that claimed 1934 was hotter than 1998. Cox then asked if NASA, the Australian Academy of Science, and the Met Office in the UK were all collaborating to manipulate global temperature data, to which Roberts asked if he was being accused of claiming they were all collaborating, to which Cox responded: "What, they've all manipulated it in the same way and accidentally got to the same answer? Is that what you're saying?"

Roberts stated in 2016 that he did not identify as a "sovereign citizen".

Roberts commented on the 2016 US presidential election by stating that "the only safe space for Hillary to occupy is a prison cell", and that he'd "settle for [her] going to Guantanamo, along with other terrorists". Roberts stated that his party, Pauline Hanson's One Nation, had hired former Trump economic adviser, Darren Brady Nelson.

Following Roberts's birth in India, the UK High Commission registered his birth as a Citizen of the United Kingdom and Colonies, and the Australian Trade Commissioner made an entry in his mother's passport that he "is the child of an Australian citizen but has not acquired Australian citizenship". The British nationality experts' opinion was that Roberts became a British citizen at birth (whether registered or not), and ceased to be a British citizen on 5 December 2016 when his renunciation was registered. Keane J found that Roberts knew he did not become an Australian citizen until May 1974 and that, when he nominated for the Senate, he knew there was a possibility that he might have been, and remained, a citizen of the United Kingdom. Keane J found that his actions before nomination had been ineffectual to renounce his UK citizenship, which had been belatedly renounced on 5 December 2016.

Roberts promotes climate conspiracy theories, and does not accept the scientific consensus on climate change. He is the leader of the Galileo Movement, established in 2011. A 2011 Scientific American article on the group stated that it "recycles many of the same straw man arguments and distortions about the science that other groups have previously employed".

In 2011, Roberts wrote an affidavit to then Prime Minister Julia Gillard – addressing her as "The Woman, Julia-Eileen: Gillard., acting as The Honourable JULIA EILEEN GILLARD" — demanding that she sign a contract exempting him from paying the carbon tax and compensation of up to $280,000 if she didn't provide him with disclosure on 28 points, including evidence that "the Commonwealth of Australia CIK# 000805157 is not a corporation registered on the United States of America securities exchange". Roberts signed himself as "Malcolm-Ieuan: Roberts., the living soul". Roberts has used this form of sovereign citizen address since, namely in a list of acknowledgements he wrote in 2013.

Roberts' major interest and activity since ending his mining career is the denial of climate change. The catalyst was the 2006 film, An Inconvenient Truth on television.

From 2006 until his election to the Senate, Roberts was a full-time political activist, speaking at rallies against the Labor Government's carbon tax, working for the climate change denying Galileo Movement, and sending hundreds of emails to political, scientific and media figures on the topic. He also met politicians, had universities launch academic inquiries into climate scientists and sent legal letters demanding the resignation of government ministers.

Roberts served as chairman of the board of the Brisbane Montessori School from 1999 until 2003 and served voluntarily on the advisory board (as a parent representative member) of the International Montessori Council from 2000 until 2008. Timothy Seldin, chairman of the Montessori Foundation, stated that Roberts' views "are not representative of Dr Montessori's global vision, and do not reflect the views of the Montessori Foundation or the International Montessori Council".

That was the end of Roberts' mining career. With his wife, in 1994 he started a management consultancy, Catalyst For Corporate Performance, and became involved in Eastern and alternative self-help techniques including meditation.

From 1982 to 1988 Roberts worked as a manager for Coal & Allied at West Wallsend, New South Wales. The mine proved to be unprofitable due to its location, leading to its sale in 1988, at which time Roberts took a redundancy package. After completing an MBA, Roberts was appointed general manager at the Gordonstone coal mine in Queensland, the largest underground mine in Australia. Roberts left the role three years later. According to Roberts he resigned due to a lack of support during an industrial dispute, but others have suggested that he was let go after cost overruns at the mine.

In 1977, Roberts began work as a coalface miner. During this time, until 1979, he worked in this role at five different mines across Australia before becoming a mining engineer. Thereafter, he worked as an engineer and general manager for various companies such as Peabody Coal Company, Consolidation Coal Company and Atlantic Richfield, though he had not held paid employment for eight years prior to his election in 2016.

Roberts is an advocate for freedom of speech, having called for the repeal of section 18C of the Racial Discrimination Act 1975, which makes it an offence to publicly "offend, insult, humiliate or intimidate" another person because of their race. He believes the 1995 section of the law was passed to "nobble" Andrew Bolt, a journalist who did not come to prominence until the early 2000s and was taken to court in 2011 by a group of Aboriginal people who were racially discriminated by an article he wrote in The Herald Sun, ordered to pay their legal costs, apologise and not publish the article again.

Malcolm Ieuan Roberts (born 3 May 1955) is an Australian politician for Pauline Hanson's One Nation. He sat as a member of the Australian Senate, representing Queensland, until his 2016 election was declared invalid by the High Court of Australia in 2017. He was then elected Senator for Queensland in the 2019 Australian federal election.

Roberts' specific objection related to charts from Icelandic stations at Vestmannaeyjar and Teigarhorn, where temperatures from the 1930s and 1940s were adjusted down, removing the apparent warming recorded at that time. However a senior Icelandic meteorologist with a specialty in historical climatology emailed Roberts that the temperature adjustments, which were made because of a daytime bias and relocation of one of the stations, were "quite sound ... absolutely necessary and well founded".
