The tight-knit Port Lincoln community is paying emotional tributes to the businessman and his two sons who died when their car drove at speed off a jetty.
Damien Little, described as a businessman in his 30s, drove the family's Ford station wagon into Boston Bay with children Koda, 4, and toddler Hunter on board.
Today the jetty is lined with flowers and teddy bears while Police confirmed the incident was not being treated as an accident.
The children had been described as "vivacious, sensational and beautiful” children by neighbors and Koda, who was due to start kindergarten this year, was often seen helping his father gardening with toy tools and wheelbarrow.
Port Lincoln Mayor Bruce Green said the community was in shock.
“First there is a sense of disbelief and then it moves to grief,” he said.
“The community will still be digesting the event and coming to terms with the tragedy."
On Twitter, meanwhile, the tragic story has struck a nerve.
