Yes, there are historical records of cannibalism involving murdered children among the Aborigines of Australia. According to anthropologist Carl Lumholtz, infanticide was ‘especially common… when there is a scarcity of food,’ and he reported that under these dire circumstances, the child might be consumed.
Lumholtz’s account from Western Queensland illustrates a horrific scene in which a three-week-old half-caste child was choked to death, then roasted and eaten by the community—despite their long contact with white settlers.
Furthermore, William Buckley witnessed the brutal killing of a deformed child; afterward, an older boy was forced to eat the remains to ward off evil, a practice linked to the mother’s mental state and the moon’s influence. Bennett also recorded a case where a ‘weak and sickly’ child was killed and eaten simply because the hungry parents found it too troublesome.
