Dutton is only the second Liberal leader after Downer outside of New South Wales and Victoria. Notwithstanding the party's inaugural leader and deputy leader Robert Menzies and Eric Harrison who had continued with their leadership positions from the previous United Australia Party, the election of Dutton as leader and Ley as his deputy marks the first time that both a new leader and new deputy leader were elected unopposed simultaneously.
Meanwhile, deputy leader and outgoing Treasurer Josh Frydenberg lost his seat of Kooyong in the election, leaving the position open for election.[8] He was considered a likely successor to Morrison if he had been re-elected to Parliament.[9]
Due to Dutton being a staunch conservative from the Right faction of the Liberal Party, Dutton's election as leader of the Liberal Party was received negatively by many.
"I think there will be a lot of children who have watched a lot of Harry Potter films who will be very frightened of what they are seeing on TV at night. I am saying he looks a bit like Voldemort. We will see whether he can do what he promised he would do when he was last running for leader, which is smile more."[21]
Plibersek later apologised. In a radio interview, Dutton called the claims "unfortunate" but "water off a duck's back", also noting that he wasn't "bald by choice" and was diagnosed with a skin condition several years ago.[21] Plibersek's apology was welcomed by newly-elected Prime MinisterAnthony Albanese in an interview with ABC News.[21]
"He's an extremist and I don't think he fits with modern Australia at all, and he doesn't seem to listen, he's extremely conservative. I actually don't think he's that smart, I've seen him present on things I don't really pick up, there's much there, as opposed to Scott Morrison, who is a clever guy. I don't pick up that Peter Dutton is fit to be Prime Minister."[23]
