Clovers and lucerne were the first crops, later supplemented with grasses. Pastures were either cut for hay or grazed by livestock.

By 1949 the experiment had proved so successful that several hundred acres of pasture were being irrigated by contour layout for grazing.

In 1954 a small orchard was developed. Some of these original grapefruit and orange trees planted then still exist in the now greatly expanded IMPI orchard.

In the 1960's, a proposal was made for a large dam (Chowilla) to be built just down stream from Lindsay Point. The dam would inundate a large area and Goverments proceeded to compulsorily acquire that land, including Kempe's home, half the orchard and much of the irrigated pasture. The project was abandoned in 1968. The Cant family purchased the remaining orchard and adjacent highland in 1969 and all the compulsorily aquired farm land in 1995.
