Career
He is a product of Saint Anthony"s College, Kandy, where he captained the college rugby team Bistamin played at Number 8 third-row-forward. Bisthamin represented the country at the Asian Rugby tournament in 2007.
On November 22, 2008, Bisthamin faced career-threatening injuries to the head and spinal cord when he fell from an upper floor of a restaurant at the George R de Silva Shopping Complex in Kandy.
He was unconscious and rushed to the Kandy General Hospital and treated in the intensive-care unit for Brain haemorrhage. He regained consciousness after three weeks.
On 2008, the exclusion of Bistamin from the Sri Lanka National Rugby Team ahead of Asian Five Nation Rugby Championship in Taiwan created a controversy with the second set of selectors led by Rohan Abeykoon protesting against the nepotistic move by Minister of Sports at that time, Gamini Lokuge.
