Plans are under way that could make Western Australia the flying fox capital of the world.

On Sunday Premier Mark McGowan confirmed the state was looking at putting a zip line from the top of the Matagarup bridge to the stadium precinct.

On Monday a private operator confirmed it wanted to build the world's longest zip line in Tom Price and one of the world's fastest from the top of Brookfield Place to Elizabeth Quay.

Mr McGowan told 6PR's Simon Beaumont the Matagarup Bridge will feature a bridge climb and flying fox, which would boost tourism in the precinct.
