AN OLYMPICS feasability study promised last year is yet to begin as councils including the Sunshine Coast react to their Games dreams being crushed.

Sunshine Coast Mayor Mark Jamieson backed a South East Queensland Council of Mayors proposal in July last year for a detailed investigation into bringing the 2028 Olympics to the region.

Sunshine Coast councillors made their support official two months later, committing up to $214,000 to find out whether or not making a bid was in the region's interests.

They joined Brisbane, Ipswich, Lockyer Valley, Redland, Scenic Rim, Somerset and Toowoomba in jointly funding the study.

Gold Coast, Logan and Moreton Bay councils opted out of contributing.

However, the International Olympic Committee's decision last month to award the 2024 and 2028 Games at the same time dashed south-east Queensland's hopes.

The 2028 Games will be played out in Los Angeles, with the 2024 Games likely to be held in Paris.

Council of Mayors chair and Lord Mayor of Brisbane, Graham Quirk, said the Olympic committee's decision had not come as a surprise.

"The Council of Mayors were given a heads-up by the International Olympic Committee they were considering awarding both the 2024 and 2028 Olympic Games later this year,” Cr Quirk said.

"The feasibility works associated with the potential bid are identifying and prioritising the future infrastructure needs of south-east Queensland and that is very important for the future of our region whether or not we have an Olympic Games.”

As a result, the project plan has been revised and negotiations refocused with potential tenderers.

A decision on which company will do the study is yet to be made.

A Sunshine Coast Council spokesman said the study was about cataloguing and defining the core infrastructure needs for south-east Queensland.

"As a result of this work, participating councils will receive highly valuable information and insights that will underpin future planning and decision making on improving the liveability, functionality and connectedness of south-east Queensland in the future - irrespective of whether any future Olympic bid proceeds,” the spokesman said.

He reaffirmed the council's commitment of up to $214,000.

"The participating mayors of south-east Queensland have always seen the feasibility study and associated investigations as an opportunity to identify significant improvements in connecting infrastructure which will better link south-east Queensland and to have that considered in a robust, planned and considered manner.

"Sunshine Coast Council has always recognised the longer term benefit this exercise would provide, not only for the residents of this region, but to the broader south-east Queensland in how we position ourselves both domestically and globally.”

The response had a different focus to the pitch Cr Jamieson made in an opinion piece published in the Daily on July 28 last year.

"The feasibility study will be conducted over the next 12 months and will help us determine whether we proceed to make a bid for 2028,” Cr Jamieson wrote.

"While no figures have been determined so far, in all likelihood if we secured the hosting of the 2028 Olympics, the economic benefit that the Sunshine Coast would derive from this single event alone would far exceed that of any other major event that council currently sponsors.

"Indeed, the potential economic benefit would likely exceed the total of the entire major events portfolio currently sponsored by council.

"That is why this bid is definitely worth exploring.”
