This excellent tome produced by Ivor de Krester has been loaned to me by Warwick and Peggy de Kretser of Adelaide — simple souls who espouse no airs and are friends with all and sundry. As a youngster from the 1950s Bridge on the River Kwai generation in Ceylon I knew of Warwick as a cricketer. Here in Adelaide I discovered that he had been a juvenile motor-cycle hotshot who had bagged several prizes in races at Katukurundu and upcountry. This sporting field was not part of my horizon then in the 1950s and 1960s.
For Sri Lankans who have migrated to Australia, of course, the name De Kretser is etched firmly in their minds because he was prominent enough in his career to be elevated to the position of Governor, Victoria (2006-11) ; while Michelle De Kretser has carved out a career as a novelist and participated in several literary festivals (note https://www.theguardian.com/books/2017/nov/11/we-are-not-very-caring-michelle-de-kretser-on-australian-society).
