The siblings were children when their family left Sri Lanka for a new life in Sydney.
Calvin was a constant in his sister's life.
"It was the four of us here," she said.
"Whenever I'd turn a corner I'd see him sitting at the dining table because he would study on the table," she said.
"I would see him in the kitchen grabbing something to eat."
Calvin was with two other boys at the time he died.
