The year 12 student said she had her application to paint her artwork on the wall approved in June this year.
“It has been a dream of mine for the past three years and after applying for a spot in March of this year, my application and artwork was approved,” Cassidy Dillon said.
“I went to Sydney in the school holidays and completed the work over four days.”
Her work comprised of a dolphin with a mandala design in black and white, featured on a stunning blue background and signed off as ‘@cassidydesigns’.
The Bondi Beach Sea Wall is a Sydney icon and has been in operation since the 1970’s.
Throughout this time it has featured artworks of some of the best-known street artists from Australia and around the world.
Trinity College, Beenleigh Student Well-Being Leader, Ms Jasmine Brown said: “It is always so inspirational to see our young people setting high expectations and goals for themselves and then watching them become a reality.”
“Cassidy’s dolphin artwork is amazing and such a great accomplishment.
“Your Trinity family is very proud of you.” Ms Brown said.
Cassidy’s artwork will remain on the sea wall for six months, and will then be painted over by another artist – reflecting the dynamic and ever-changing character of Bondi.
