O.D. Watson, a committed naturalist, became known as "the poet of the Yundurup Delta" while he lived on Culeenup Island from 1961 until January 1973 when he moved to Albany, Western Australia. A collection of letters written to Watson by his friend
Ian Mudie (q.v.) between 1968 and 1974 is held by the National Library of Australia (MS6944).
