Dennis Jensen

In August 2017, Jensen sent an email to former Liberal colleagues, saying he had joined the Australian Conservatives party started by Cory Bernardi, and urging them to follow him.

Jensen lost Liberal preselection in Tangney for the 2016 federal election. It was revealed he had written an erotic fiction novel named "The Skywarriors" in which Indonesia invades Australia. Jensen labelled it "dirty tricks" and an "absolute smear campaign". Former party state director Ben Morton won preselection.

Dr Jensen is a sceptic concerning human-induced global warming and, on behalf of the Lavoisier Group, organised the release of a book entitled Nine Facts About Climate Change by former mining CEO Ray Evans. In February 2007 during a Parliamentary sitting, Jensen quoted the then IPCC vice chairman Yuri Izrael, who had stated that "there is no proven link between human activity and global warming".

In 2006, Jensen lost his preselection for Tangney for the 2007 federal election, but won it back with the support of the state executive and prime minister John Howard. He lost preselection again for the 2010 election, but once again the state executive intervened and restored him as Liberal candidate.

Jensen was the Liberal candidate for the Division of Corio, Victoria at the 1998 election.
