I found the following description of Australian aborigine hunting preferences relevant to the kangaroo discussion: The great challenge for the Aborigine was to obtain enough dietary fat. They were close observers of nature and knew just when certain animals were at their fattest. For example, kangaroos were fat when the fern leaf wattle was in flower; possums when the apple tree was in bloom. Other signs indicated when the carpet snake, kangaroo rat, mussels, oysters, turtles and eels were fat and at their best. Except in times of drought or famine, the Aborigine rejected kangaroos that were too lean they were not worth carrying back to camp.1 During periods of abundance animals were slaughtered ruthlessly, and only the best and fattest parts of the killed game were eaten. Favorite foods were fat from the intestines of marsupials and from emus. Highly saturated kidney fat from the possum was often eaten raw. The dugong, a large seagoing mammal, was another source of fat available to natives on the coasts. Other sources of fat included eggs from both birds and reptiles and a great variety of insects. Chief among them was the witchety grub, or moth larva, found in rotting trunks of trees. These succulent treats often over six inches long were eaten both raw and cooked. Fat content of the dried grub is as high as 67%. The green tree ant was another source of valuable fat, with a fat-to-protein ration of about 12 to one. Another important seasonal food in some parts of the country was the begong moth. The moths were knocked off rock walls on which they gathered in large numbers, or smoked out of caves or crevices. They were roasted on the spot or ground up for future use. Moth abdomens are the size of a small peanut and are rich in fat.
