"Since the loss of Azaria I have had an abiding fear and paranoia about safety around dingoes," he said, Australian Associated Press reported.
"They send a shudder up my spine. It is a hell I have to endure."
Coroner Elizabeth Morris will hand down her findings at a later date but the court was told that authorities regarded dingoes as responsible for many attacks in the years since Azaria's disappearance.
Anna Lade, a former police officer who has investigated the case for the court, said that dingoes had been responsible for many attacks causing injuries, including three deaths.
Asked whether the figure of 239 attacks causing injury to people between 1990 and 2011 was correct, Lade replied: "I am prepared to accept that."
Stuart Tipple, a lawyer who has long represented the Chamberlains, said the case still held "so many unanswered questions".
"You are never going to have a body, you are never going to be able to have a post-mortem but looking back now I have to agree that it was a dingo," he told ABC radio."I think the evidence now is such that it compels one to make that finding."
