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.
She said it prompted her to leave her sports car at home, hop in a van and take every day as it came.
"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 has travelled across the country, including recently through Eyre Peninsula which included stops at Ceduna, Streaky Bay, Coffin Bay and Port Lincoln.
Ms Moncrieff said she never intended to become an activist but on her travels had collected stickers and posters displayed in her van.
"I never intended to get into a van and look like a hippie," she joked.
"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.
"I'm doing it for the children of this nation, the next generation."
She said Equinor's proposal could have a dire effect on local tourism and the whales and marine life.
"The government doesn't consider us, doesn't consider the community or climate and I don't know why," she said.
"There's not enough people standing up and speaking out, especially in small country towns."
She said she would advocate for the Great Australian Bight to be world heritage listed by the UN and asked people to sign the petition at bight2020.com.
Ms Moncrieff said she had spoken to councils on her travels and believed they should be representing the best interest of their townships.
She said a lot of people in Ceduna and Streaky Bay had been "guarded in putting forth concerns", while only one person in Port Lincoln told her they were for drilling in the Bight for the employment opportunities.
She said on her return to Adelaide she was considering a march on parliament as the November 14 date for the NOPSEMA decision approaches.
