[13] Wellington gave confidence and supply support to Labor to form government, giving it the majority of 45 out of 89 seats in parliament, and consequently the previous Liberal National government under the leadership of Campbell Newman, who lost his seat of Ashgrove, lost office after one term.

After Labor's retraction of endorsement for MP Rick Williams on 27 October 2017, the party's seat count dropped to 41, equalling that of the LNP.

[14][15] On 29 October Palaszczuk asked the Acting Governor Catherine Holmes to dissolve parliament and a writ was issued for a 25 November state election.

The electorates of Bancroft, Bonney, Cooper, Hill, Jordan, Kurwongbah, Macalister, Maiwar, McConnel, Miller, Ninderry, Oodgeroo, Scenic Rim, Theodore, Toohey, and Traeger were created.

Independent: Sandy Bolton (Noosa)This election resulted in a number of historical milestones being achieved for the representation in the Queensland Parliament.

These include: Prior to the election, the Shooting Industry Foundation of Australia used $550,000 to launch an advertising campaign, named Flick'em, in an effort to urge voters to put both major parties last in ballot paper preferences.

[21][43] The Electoral Act requires the Governor to issue writs for a general election no more than four days after the Legislative Assembly is dissolved or expires.

Following Agriculture Minister Bill Byrne's resignation on health grounds and the disendorsement of Pumicestone MP Rick Williams,[45] on Sunday 29 October 2017, she announced the election would be held on 25 November 2017.

[46] Pauline Hanson described this as a "cowardly" move, given that she was overseas on a federal parliamentary trip and would be delayed in starting her One Nation party's campaign.

[47] 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,[48] and the record strength of the Greens in several urban seats bolstered by Brisbane's first Green councillor Jonathan Sriranganathan (then known as Sri) being elected in 2016.

[49] In January 2017, One Nation disendorsed its Bundamba candidate Shan Ju Lin after her anti-gay social media post.

[50] In December 2016, Andy Semple withdrew as a candidate for Currumbin, after the party told him to delete an LGBT joke on Twitter.

One Nation also made an agreement with Katter's Australia Party, not to challenge the two sitting KAP MPs in their respective seats.
