Graeme Pearman and Carmen Lawrence will visit WA's state parliament in Perth on Tuesday morning to call for the ban on fracking, with an open letter that also includes support from 2003 Australian of the Year Fiona Stanley and Climate Council chief Tim Flannery.

The group penned the letter as they await the release of the final report by the WA Independent Scientific Panel Inquiry into fracking.

The WA Labor government called for the inquiry to decide on the future of the method after placing a moratorium on it throughout the state, as well as banning onshore gas fracking in the Perth, South West and Peel regions.
