It is a community deed that Ms Sutherland, a longtime resident of Anna Bay, takes very seriously in the hope it will set an example to others to be more environmentally conscious.

"We live in a beautiful part of the world and the beach is a place to be enjoyed by everyone," she said.

"I regularly walk, or jog, along the beach and from time to time I will take along my garbage bags, collect the rubbish and dump it in the bins in order to keep the beach clean."

Ms Sutherland says that over the years she has come across some rather unusual items, ranging from clothing, furniture, sheets, towels and shoes to food and, unfortunately, tonnes of plastic bags and bottles.

Some of her more interesting finds were horse bones, camping gear and car parts and about two weeks she came across a cap with an inscription 'Australian Sailing Team' and a yellow and green sail design with the Southern Cross featured on the front.

"I was sifting through clumps of seaweed that had been washed up onto Birubi Beach about half a kilometre from the surf club following a series of storms when I noticed the white cap," Ms Sutherland said.

"At first I didn't think much of it until I saw the insignia so I decided to take it home and soon realised it had the slightly faded hand-written name 'Blackers' on the inside.

"I Googled the name and realised that it most likely belonged to former Olympic bronze medalist Michael Blackburn, who was also the 2020 Australian sailing national lead coach.

"I'm guessing that Blackers is his nickname."

The cap mystery intrigued Ms Sutherland and asked if the Examiner could solve the mystery of how the cap got to surface on an Anna Bay beach. Investigations are ongoing.
