Edwin Verburg

His mother’s father, Dutch engineer and agriculturist Edwin Verburg  (1869-1965), was a pioneer horticulturist in the Northern Territory. He married Tom’s grandmother, Anmilil, a Traditional Owner of Adelaide River and the region 100 kilometres south of Darwin where he established a farm where the township of Adelaide River stands today. In the 1920s he had fields of rice and maize, vegetables and tropical fruit where he introduced irrigation and built the first dam with centrifugal pumps.

​With a few blacks to help him, Verburg constructed a grand little weir in the Adelaide River that cost him £3000. In the photo below, the concrete remnants in the river are from Edwin Verburg’s 1925 weir . During WWII the Army further damaged the remnants when they constructed the Low-level bridge that still exists. A second crossing, this time dedicated to road transport, the Edwin Verburg Bridge, now carries the highway across the river. It was opened on 27 March 1980.

Tom’s father was also interested in horticulture and his first job was growing tobacco in the Darwin Botanical Gardens.

His introduction to the Calmas was through Adrian Van Leest, of Campbell, a grower of family heritage tomatoes and a keen gardener. Heather Calma says that through Adrian, one year Tom grew a variety of potatoes called ‘Heather’ which had a purple skin.
