A much-touted 2032 Olympic review is set to solve a multi-billion-dollar transport problem to ensure the Brisbane Games are not derailed.
Concerns have been raised after it emerged major rail projects on the Gold Coast and Sunshine Coast might not be finished in time to meet 2032 Olympic demand.
But Olympics Minister Tim Mander assured the 100-day infrastructure review would come up with a solution for appropriate transport options.
"(The review) is not only looking at facilities - they're looking at all the infrastructure that's required to run the Games, and they will be taking all that information into account when they come with their final recommendations," he told reporters on Thursday.
"We'll ensure the Games are successful and there is good mobility for people to get around the southeast and beyond."
Doubts over the rail project's future followed a submission to the review that claimed the cost of the Sunshine Coast rail extension to Maroochydore could almost double from $12 billion to more than $20 billion.
The project to connect Brisbane, Moreton Bay and the Sunshine Coast was recently taken off the federal government's infrastructure priority list - a move Deputy Premier Jarrod Bleijie said sounded alarm bells for funding cuts.
The state and federal governments have committed $5.5 billion to complete stage one.
Mr Bleijie said the submission's figures that Sunshine Coast rail could cost $500,000 a metre were "alarming" but the federal government's move to deprioritise the project was of greater concern.
He has written to federal Infrastructure Minister Catherine King to demand the rail project's return to the priority list so it can be completed.
Mr Bleijie also revealed stage four of the Gold Coast light rail - Burleigh Heads to Coolangatta - was in doubt with the state government to conduct a second review of the project before continuing with the build.
It will look at the modes, types of transport and routes.
Stage four of the project has long been debated after the former Labor government revealed costs could rise to $7.6 billion.
He said the goal remained to complete the rail project by the 2032 Olympics but further consultation with the community was needed.
The state's independent 100-day review of infrastructure, including stadiums and transport options, is expected to deliver a 2032 blueprint by March.
It was commissioned by the Liberal National government after the state's former Labor leaders dismissed a previous review's recommendation to build a $3.4 billion stadium in Brisbane's Victoria Park as the Olympics centrepiece.
Meanwhile, golf great Greg Norman has joined the 24-strong 2032 Olympics organising board.
The former world No.1 and two-time major winner was one of Australia's greatest sportsmen and a successful businessperson, Mr Mander said, and would be a valuable addition.
"It's good to have people that know sport at the highest level," he said.
"And we've got some former Olympians on the board but Greg has an incredible business brain as well, and we want to make sure that we run the Games in a way that's most cost-effective."
