In 2013, 6400 Iranian asylum-seekers arrived in Australia on Indonesian fishing boats, many of them had lost their families or were injured seriously in horrible boat tragedies. A father and his 7-year-old son were struck by lightening on the boat and the son was burned severely. After a while they were released from an Australian detention centre and started a new life in Australia but with many mental disorders and physical ailments. Psychologists said to the father that his son's brain had suffered drastic changes, and that it would be very difficult to get his courage and hope back.
