The Independent and self-proclaimed "climate activist" launched his Group "L" ticket for the NSW Upper House on the South Coast, with the promise to push for more renewable energy, and fight against government corruption. 

Mr Buckingham resigned from the Greens last year, ripping up the party's logo as he made the announcement. His resignation followed former colleague Jenny Leong's calls for him to quit over sexual harassment allegations made by a former party staffer.

Ahead of the March 23 election, Mr Buckingham told the South Coast community he'd put them, and the environment first. 

"My group and I are focusing unashamedly on the environment and putting a community voice into parliament, free from politics and free from vested interests," he said. 

"I've been a successful campaigner across NSW in my time, stopping coal seam gas, fighting to protect the drinking water catchments and as an independent i'm putting the community before party politics." 

Mr Buckingham complimented the South Coast for its pristine beaches and waterways and said he was passionate about climate change and the banning of single use plastics. 

"Kiama is clearly a magnificent and beautiful spot with one of the most incredible coastlines that we can't take for granted," he said.

"People of Kiama and the South Coast should be congratulated for their efforts, and we should move to phase out single use plastics, move to ban the sale of plastic shopping bags." 

A video of Mr Buckingham visiting the Darling River went viral earlier this year, after he threw up at the site of mass fish deaths. Mr Buckingham travelled to Menindee, near Broken Hill to continue to campaign for the health of the state's river system.

He said while the Darling River was a fair distance from the South Coast, it was something people in the region should still be concerned about. 

"I would urge the people of Kiama and the South Coast to think about climate change when they vote, and to consider what is happening to our inland river systems," he said. 

"Even though Kiama is far away, fish kills mean a dead ecosystem. I've championed the cause of protecting our river systems and I believe that should be at the forefront of government decision making." 

Ahead of the election, Mr Buckingham and his ticket of 15 community advocates and environmental campaigners, have refused to make preference deals and will trust voters to allocate their own choices for the NSW Upper House vote.

"Me and my party will not be directing preferences, because we don't believe in dodgy political backroom tactics," he said. 

"If you vote for us, that is where the vote stays. People are sick of the corruption,the last thing they want is their vote shifted to other parties."
