In 1925, Brisbane was transformed. Twenty local councils—cities, towns, shires, and partial shires—merged into a single Greater Brisbane under the City of Brisbane Act 1924. This bold move aimed to unify a rapidly growing region in pursuit of coordinated infrastructure, planning, and civic services. The act created a new council led by a Lord Mayor and 20 aldermen; the first council convened on 18 March 1925, and the full amalgamation took effect on 1 October that year, with William Jolly as the inaugural Lord Mayor.

To mark 100 years since this pivotal moment, the “Greater Brisbane Centenary: 1925 – 2025” initiative brings history to life — a heartfelt homage spearheaded by a coalition of more than 50 history and heritage groups, with support from Brisbane City Council. Queensland Irish Association will be joining in the Greater Brisbane Centenary ‘Brisbane 100: One City Together’ celebrations on Wednesday, 1 October at Brisbane City Hall from 10am to 4pm. 

At the 1915 state election, both the Liberal Premier, Digby Denham, and the Labor Leader of the Opposition and prominent Queensland Irish Association member, Thomas Ryan, supported the Greater Brisbane concept. Thomas Ryan became Premier of Queensland in 1915. His government laid the groundwork for municipal reform, advocating for better coordination among local councils.

As October approaches, the centenary celebrations gather pace. On 1 October, Brisbane 100 – One City Together will fill City Hall with activities, displays, and a community focus on how far the city has come.

On 11 October, the Royal Historical Society of Queensland, together with the Centenary Committee, Brisbane City Council, and the Museum of Brisbane, will present a full-day history conference with leading scholars and speakers. On 12 October, Marchant Park will host the unveiling of a plaque and information board to commemorate the former Kedron Shire Council.
