A small group of 11 took to the highway in front of Potoroo Palace to participate in statewide Koala Action Day.
Assistant manager of Potoroo Palace Maree Bishop organised the event in collaboration with the local Far South Coast Koala Action group.
Ms Bishop said she had heard about the statewide rally through a volunteer who had rung up telling her about the large event that was to be held at Hyde Park in Sydney.
The Sydney Save Our Koalas website had encouraged citizens to get involved and take a stand in halting the deforestation in areas such as Figtree Hill and Mt Gilead where developments threaten to destroy koala habitat.
Ms Bishop said it had been so easy to get involved and all they had to prepare were some of their own placards and signage to take to the street on Sunday, March 21.
"I thought it was a fantastic idea to get involved since we're right on the highway," Ms Bishop said.
The goal was to attract attention of oncoming traffic as well as gain traction on social media by posting photos tagging #SaveOurKoalas.
"We received a really positive response, people encouraged us with beeps. We also had some negative responses with people yelling out offensive comments, but that's to be expected," Ms Bishop said.
Ms Bishop said the campaign was close to home for her having lived most of her life in Queensland and having witnessed the gradual demise of koalas over the past 40 years.
"I haven't seen a koala in over 20 years and I remember places where they had been abundant.
"I'd like my grandchildren to be able to see a koala in the wild," she said.
World Wildlife Fund have stated koalas are a vulnerable species in QLD, NSW and ACT, and said the main threats they face are tree clearing and global warming.
