According to the national environment department, there was more than 500,000km squared of tussock grasslands across Australia, including vegetation like Mitchell and tall bunch grasses in 2017.
Dr Mason said these act as regenerating ecosystems, producing grain and tubers.
"There's a huge opportunity there for us to really look at our current agricultural systems and see where we can learn from traditional knowledge and harness the power of those landscapes," he said.
Black Duck Foods supplies native grain flour from kangaroo grass and dancing grass to fine dining restaurants like Ben Shewry's Attica in Melbourne, as well as several bakers and restaurants around Australia.
"We can't supply enough flour at the moment to get into these types of systems," Dr Mason said.
Dr Mason said native grain flours, with a unique, "hard to describe" taste and full-bodied, whole grain profiles, are more flavoursome than standard wheat flour.
Mainstreaming native flour
Chef Ben Shewry told ACM processed and heavily refined wheat flours were flavourless.
"[Native grain flours] are delicious, they have heaps of character and bucket loads of flavour," Mr Shewry said.
The award-winning chef described the distinctive flavour profile of ganalay, or Mitchell grass, grain flour as sweet and nutty.
His restaurant, Attica, only serves native animal proteins and is working towards replacing wheat with native grains.
It will soon serve a native grain flour bread, with dishes like pikelets and pasta also being experimented with.
"My long term hope for native grain flours is that they can become mainstream," Mr Shewry said.
"Everything native grains need exists here already in this landscape - that's why they're endemic to this country."
Indigenous knowledge not 'myth and legend'
Kamilaroi man Bradley Moggridge said a lack of trust and respect for Indigenous knowledge was holding back some research and policy, especially around water management.
"One day we'll have Indigenous knowledge treated as an equal rather than myth and legend," the Canberra University Associate Professor of Indigenous water science said.
Associate Professor Moggridge is exploring ways traditional knowledge can work with Western science to map water flows in Australia.
