A group of South East Queensland mayors have backed Brisbane's bid for an Olympic Games in 2028.

Backing from the 11 other councils in the region is the first step of many that will be needed to get an official Brisbane bid off the ground.

"This is not something that's going to be occurring overnight. There is a long, long way to go in terms of this journey," Lord Mayor Graham Quirk said on Friday afternoon.

"As a region we have a great offering and we believe that collectively we ought to now commence discussions at other levels. We'll be advising the Australian Olympic Committee...the Queensland Government and Australian Government of our interest in having further discussions around this."
