A lady dubbed the 'green nomad' is on the final leg of her Australia-wide trip to raise awareness about Equinor's proposal to drill for oil in the Great Australian Bight.
Kay Moncrieff said she felt "shattered" after the 2019 national election result and wondered what she could do for the next three years.
"I couldn't sleep that night," she said.
She said she then packed up her van and started a journey which has taken her around the entire country, visiting coastal towns and speaking to whoever would listen about the proposal and her concerns should it end in an oil spill.
"People in the north, east and west (of Australia) were ignorant about (drilling in the Bight) and few people knew about it," she said.
"It's a huge wake-up call when I tell people this area here is likely to be devastated.
"People hug me in the street, wave to me in the van but it's not about me, I'm doing it for the children...all it takes is a bit of courage."
She said the conversations she had with people across the country had shown a "silent majority" had concerns about the proposal.
After nearly six months on the road she recently reached the Eyre Peninsula, travelling down the West Coast to Port Lincoln, then back up through Port Neill, Cleve and Cowell last week.
She said it had been interesting to finally reach the epicentre of the discussion and see what the locals thought.
"The threat is more real to them, they're worried abou their livelihood, they're worried about their children and they're worried about their future."
Ms Moncrieff said Equinor's proposal could have a dire effect on local tourism and the whales and marine life.
She said should an oil spill occur, the impacts on the seafood and tourism industries would have a major effect on Eastern Eyre Peninsula towns as well as towns directly on the Bight, with the state's "pristine" image wiped away.
She said current tourism and export business would simply flow on to another country with an intact reputation.
"It's about making people aware and to stand up because if we don't we could get devastated - we'll be seen as a polluted country."
She said she would advocate for the Great Australian Bight to be World Heritage listed by the United Nations and asked people to sign the petition at bight2020.com.
