Kangaroo Island residents opposed to oil drilling in the Great Australian Bight will participate in a protest at Vivonne Bay.
The protesters will meet at the beach at 12noon on Saturday, March 16 and mark out a message in the sand.
There will be simultaneous "Paddle Out" protests at Port Lincoln, Streaky Bay and Ceduna.
KI event organiser Linda Irwin-Oak said she hoped as many people as possible could attend Saturday's action, which followed on from other well-attended protests including a paddle out at Victor Harbor two weeks ago.
"Make sure to bring something to show the camera and the world, even if it’s a crab pot, all things ocean is what we are fighting to protect," she said.
Federal Member for Mayo, Rebekha Sharkie this week held a series of community forums on KI.
She said concern about oil drilling in the Bight was the number one environmental issue raised with her, along with proposed accommodation development in Flinders Chase National Park.
Ms Irwin-Oak also pointed to a recent poll on the Kangaroo Island Questions, Notices & Discussions posted by former KI councillor Graeme Ricketts.
The poll asked: "Should KI Council oppose oil exploration in the Great Australian Bight?"
The response on the closed page with 4100 members was 268 in the affirmative and 32 in the negative.
Page member Lisa Crago pointed out it was not the council's decision to make.
The Islander has a poll of its own below just asking more generally whether people supported oil exploration in the Bight.
