The ALP's Queensland branch and the LNP are two of six parties registered with the Electoral Commission of Queensland by October 2017, alongside the Queensland Greens, the Queensland division of Pauline Hanson's One Nation, Katter's Australian Party, and Civil Liberties, Consumer Rights, No-Tolls. Queensland's two-party dominance was threatened by the resurgence of One Nation, given former LNP MP Steve Dickson's defection to become One Nation's state leader in January 2017 and the high-profile candidacy of recently-disqualified Senator Malcolm Roberts, and the record strength of the Greens in several urban seats bolstered by Brisbane's first Green councillor Jonathan Sri being elected in 2016.
