When American entrepreneur Allen Chase was looking for a suitable site to grow the world's largest rice crop - as close as possible to the largest market, Asia - he chose an area of three-quarters of a million acres near Humpty Doo as the most suitable place. Everything looked highly favourable for a bumper crop as aerial sowing began, until an unexpected difficulty was encountered in the form of thousands of hungry magpie geese. Despite deterrent efforts ranging from clumsy scarecrows to the Army firing Bren guns, the geese repeatedly won the day, eventually forcing the rice growers to concede defeat.
