In July 2017, amid the 2017–18 Australian parliamentary eligibility crisis, Canavan resigned from Cabinet over doubt as to his eligibility to be a member of the parliament, after discovering that he might be an Italian citizen.[2] After the High Court found in October 2017 that Canavan was not an Italian citizen,[3] he was immediately reappointed to Cabinet.[4]
On 3 February 2020, he resigned again from Cabinet to support Barnaby Joyce in his unsuccessful bid for National Party leadership.[5] He also cited his failure to declare his membership of the North Queensland Cowboys, as the Northern Australia Infrastructure Facility within his Northern Australia portfolio, approved a $20 million loan for the Cowboys to build a training centre next to the North Queensland Stadium in Townsville.[15] He denied it was a breach of ministerial standards as under the North Australia Infrastructure Facility Act, he had no power to approve loans but could only reject them.
After his resignation from the Cabinet, he remained as deputy leader of the Nationals in the Senate, along with Bridget McKenzie as leader, as the other three Nationals senators were first-termers.[16][17]
Canavan has served on the "Inquiry into the destruction of 46,000 year old caves at the Juukan Gorge in the Pilbara region of Western Australia", which delivered its interim report in December 2020.[18]
In 2006, Canavan's mother had registered him as an "Italian resident abroad" with the Italian consulate in Brisbane. Canavan stated that he had been unaware of this until his mother had informed him of it following the resignation of two Greens senators over their dual citizenship.[19] The government took the view that he was not in breach of the Constitution, as the registration had not been made with his knowledge or consent. Canavan resigned from cabinet, but not from Parliament, as he had not yet been given a definitive legal view on the matter.[20]
Initially, Canavan accepted that he had Italian citizenship.[21] He then renounced it, effective 8 August 2017.[22] On the same day, on a government motion with all-party support, the Senate resolved to refer the matters of Senators Scott Ludlam, Larissa Waters and Canavan to the High Court as Court of Disputed Returns. The Attorney-General indicated that the Commonwealth would argue, in favour of Cavanan, that s 44(i) requires a personal acknowledgement of the connection, which had not occurred. Canavan spoke in support of the referral, while stating that he did not believe he was in breach of s 44(i), and said that he would not be voting in the Senate until his position was determined by the Court.[23] Later, four other members of the federal parliament were referred to the High Court, which heard the seven cases together.
In the High Court, government lawyers argued for Canavan and others that s 44(i) requires some personal acknowledgement of another citizenship, which had not occurred; in its judgment on 27 October 2017, the Court rejected this interpretation of the sub-section. For Canavan, it was argued in addition that his registration as an "Italian resident abroad" in 2006 had been incorrect in supposing that he was an Italian citizen and that, although a change in Italian citizenship law when he had been two years old could appear to have conferred Italian citizenship upon him, it could not be shown to have done so.[24] The Court accepted these points and held that Canavan had never been a citizen of Italy; accordingly, he had been validly elected.[25]: para 86 [26]
Political views
Canavan opposes same-sex marriage.[27] In 2017, when Cory Bernardi moved a motion to ban abortion on gender grounds, Canavan was one of ten MPs who voted for the motion, which was defeated with 36 votes against.[28]
Canavan is a climate change denier[29] and a prominent supporter of fossil fuels, particularly coal,[30][31] and has strongly opposed investment in renewable energy.[32] He has been referred to as one of the major players in the LNP split over climate and energy policy, frequently advocating for more coal power plants, despite their higher costs and higher emissions than alternative energies.[33] Canavan has rejected that climate change contributed to the catastrophic 2019–20 Australian bushfire season, despite evidence to the contrary.[34] His views have been rebuked by climate scientists and other members of Parliament, including Nationals MP Darren Chester.[35][36] In response to a protest in November 2018 where high school students walked out of class to protest the Australian government's inaction on climate change, he responded "I want kids to be at school to learn about how you build a mine, how you do geology, how you drill for oil and gas". He also stated "The best thing you'll learn about going to a protest is how to join the dole queue."[37] He also strongly opposes the teaching of climate change in schools, stating that children are "more interested in PewDiePie than politics", "Fortnite than fostering revolution" and that the only mining they get involved in is in Minecraft.[38]
In October 2020, he shared a picture on Facebook and Twitter that showed a vehicle with a sticker that stated "Black Coal Matters" on it, intended as a parody of the American social movement Black Lives Matter. This was posted in the wake of major racial tension following the murder of George Floyd, and Canavan was met with heavy backlash on social media.[39][40] He later defended the post as a "joke", and declared that the Black Lives Matter movement deserves "ridicule".[41] In August 2021, Canavan received widespread criticism when he took issue with the announcement that the children's entertainment group the Wiggles had recruited a further four members, who were ethnically diverse, a move he perceived as "woke", saying in an interview with The Australian newspaper: "The Wiggles are free to do what they like. It was nice while it lasted. But you go woke, you go broke." His comments were perceived by some as racially insensitive.[42][43]
In November 2021, Canavan was one of five Coalition senators who crossed the floor to vote for Pauline Hanson's proposed COVID-19 Vaccination Status (Prevention of Discrimination) Bill 2021, which would have prevented people who willingly refused the COVID-19 vaccine from being subject to any kind of mandate or consequence.[44][45] His support of the bill drew criticism and accusations of being anti-vaccine.[46] Canavan called for the rollout of the AstraZeneca vaccine to be halted, contrary to the policy of his own government and views of his colleagues.[47] In September 2023, Canavan promoted a conspiracy theory that COVID-19 vaccination increases the risk of stillbirths, citing Leading Report, an American website known for promoting misinformation.[48]
