At the
2017 Queensland state election, Dametto was the
Katter's Australian Party (KAP) candidate for the
Hinchinbrook district. He finished third on the primary vote, behind the
Liberal National Party and
One Nation. However, he overtook One Nation for second place on
Labor preferences, and then defeated LNP incumbent
Andrew Cripps on One Nation preferences. Hinchinbrook had been in the hands of the LNP or the
Nationals since 1960. In November 2021, Dametto was appointed as deputy to the party's leader
Robbie Katter. In April 2025, Dametto was given an adult caution for breach of alcohol restrictions per the
Curacoa Island alcohol management plan following a
Good Friday visit to the
Greater Palm region. Dametto helped organise the Townsville rally of the
March for Australia, an anti-immigration rally in August 2025. Dametto was warned by a member of the crowd that there were
Neo-Nazis present at the rally. Dametto defended the presence of the men and said, "Who they are I don't know, but if they can behave themselves today and don't do anything to stir anyone up, I've got no dramas with them standing and doing their own thing over there. They're Australians, I may not support what they may or may not be into but I believe that every Australian has the right to march today". In late September 2025, Dametto stated he would resign from the
Katter's Australian Party to contest the upcoming
Townsville mayoral by-election as an independent, with the election to be held in November. On 2 October 2025, it was reported Dametto had already resigned from the party and would also be resigning from state parliament for the mayoral by-election. Dametto won the by-election with a primary vote of 61.53%. ==References==
