The push for south-east Queensland to host the 2032 Olympics has received a boost with Scott Morrison throwing his "very clear" support behind the bid.

The prime minister has told International Olympics Committee president Thomas Bach "Queenslanders will always want to outdo NSW" by putting on an even better Games than Sydney in 2000.

Mr Morrison met with an "impressed" Mr Bach in Japan at the weekend, saying the government had committed to the Games bid financially.

The push is being made by a group of south-east Queensland mayors, including Brisbane's, which believes hosting the event is feasible given much of the required infrastructure already exists from last year's Gold Coast Commonwealth Games.
