A feasibility study commissioned by the South East Queensland Council of Mayors in 2019 suggested that the Games could be a catalyst for increased transport and infrastructure investment.

[16] This amount also did not include the suggested billions of dollars of greater investment in roads and public transport that would be required for the Games to be successful.

[19] A new 17–18,000-seat arena known as Brisbane Live is planned to be constructed at Roma Street Parkland; it was stated to host swimming and water polo finals events.

[19][20] The Gabba was originally slated to be demolished and rebuilt to host the ceremonies and athletics, expanding it to 50,000 seats and adding a new pedestrian plaza.

[27][28] On 13 December 2023, Premier of Queensland Steven Miles announced the establishment of a Brisbane 2032 infrastructure authority, and an independent review of the Games' venue plans.

[32] In January 2025, former Premier Annastacia Palaszczuk said that the review committee had allegedly already decided to go forth with the stadium at Victoria Park, and ABC News understands the revamped design will be a public-private partnership, and that there will be no net loss of green space.

Palaszczuk argued that this was "absolutely a ridiculous idea", and that "it's going to cost a lot more — more billions and billons of dollars that Queenslanders don't have at the moment because of the cost-of-living pressures".

The first stage of the project proposed a sports and entertainment district anchored by a new 60,000-seat stadium, as a replacement for the Gabba and a potential Olympic venue.

[34][36][37] In September 2024, former politician and Premier of Western Australia, Colin Barnett, suggested during a talk show on 4BC that the Queensland government should consider building a copy of Perth's Optus Stadium in Brisbane, which, if it were to go ahead, would save time and costs on building a new stadium from scratch, as well as giving Brisbane a modern replacement for The Gabba.

[38] In December 2024, the design firm Arcadis presented a proposal for the Victoria Park stadium, which proposes a 60,000 capacity stadium, the relocation of the Brisbane Live arena to Victoria Park, and the construction of an aquatic centre on the site of the Centenary Pool Complex, which would leave a high standard swimming facility post games.

The overall project was budgeted at A$5.4 billion, which the firm argues, in a like for like basis, is A$200 million cheaper than the combined costs of building Brisbane Live in its current state, and renovating The Gabba, Lang Park and Queensland Sport and Athletics Centre.

[39] In December 2024, the design firm HAL Architects presented their proposal for The Gabba, which proposes the demolition and rebuilding of the stadium, expanding it to 55,000 seats, the relocation of the Brisbane Live arena to opposite the stadium, and adding a new pedestrian plaza which would border with the Riverside Expressway and would also link a footpath to the Goodwill Bridge.

According to the firm, this option "is the most “logical” and cheapest", and that this, concerning the Victoria Park proposals, would not be "taking over a park that’s so incredible and pristine.”[40] In December 2024, the design firm Richard Kirk Architect, who are based in Woolloongabba, announced their proposal, to construct a new stadium across the road from The Gabba, above the Woolloongabba railway station.

According to the firm, this option would create minimal disruption to the suburb, and would not result in the relocation of tenants or the East Brisbane State School.
