Member of the Committee for Brisbane Aaron Tham pitched the idea and described it as an innovative way to transport people between the three regions.

The tourism and business lecturer at the University of the Sunshine Coast claims that, with road traffic increasing, a focus needs to be on waterways and battery-powered, carbon-neutral ferries can be a green solution.

"This is obviously triggered by observing what's happening on the highways, the cars, and the amount of time people sit behind traffic," he said, as reported by ABC.

"Obviously it needs multiple layers of Government support and private-public intervention to look at possible routes, timings and the fleet that we have."

Tham states it is a way to move people "in a safe, convenient and enjoyable way". 

Judy Benson, spokesperson for Tasmanian shipbuilder Incat, has called on Brisbane 2032 organisers to make a decision as soon as possible for vessels.

The company is already developing a 47-metre aluminium catamaran capable of carrying 600 people including crew.

"It doesn't have to be just built, it has to be designed," she said, as reported by ABC.

"They really need to decide early if they want to do something."

Some are sceptical over how modern electric ferries would handle rough conditions as Queensland's south-east is known for its dangerous coastal bars.

"The only obstacle I can see between Sunshine Coast and Brisbane is your actual traffic up the channel where you get large tankers - that may impede the speed of the ferry," said Coast Guard Mooloolaba deputy commander Lee Campbell.

"Plus the predictable weather and the unpredictable weather - sometimes we can get swells that come up."
