Summarize this content to 2000 words in 6 paragraphs The construction of Brisbane Arena – a proposed inner-city venue earmarked to host Olympic swimming – has been cast into doubt, with concerns over its $2.5 billion price tag.Fresh scrutiny of the arena comes as state cabinet looks to sign off on a new 60,000-seat stadium at Victoria Park on Monday, a day before the public release of the 100-day review into Olympic venue infrastructure and the government’s response.Under a previous funding agreement negotiated by former Labor premier Annastacia Palaszczuk, the state government would have paid for the Gabba to be rebuilt as Brisbane’s major Olympic stadium – a plan that has now been abandoned – while the federal government would have paid for the arena.Concept designs for Brisbane Live, the precursor to Brisbane Arena, at the Roma Street station site.Credit: Queensland governmentThe anticipated multibillion-dollar cost of constructing the main stadium at Victoria Park will force David Crisafulli’s LNP government to renegotiate these deals on the eve of a federal election, potentially putting Brisbane Arena at risk.The 17,000-seat covered arena was originally set to be built over the tracks at Roma Street station, and would host swimming and aquatic events with a drop-in pool.LoadingAfter former lord mayor Graham Quirk’s review of venues in 2024, the plan moved to a corner of the Roma Street Parklands near the Normanby five-ways.On Friday, Nine News reported the state government was reconsidering the venue altogether, potentially to redistribute funds across other projects for the Games.Brisbane Times understands the 100-day review, prepared by a panel of experts to deliver on a key LNP election promise, would argue for Brisbane Arena to be constructed on the old GoPrint site, near the under-construction Woolloongabba Cross River Rail station.
