It was less common in Australia thaj other Oceania but Australian aboriginal tribes also had their share in this, especially eating young children.

Here's an excerpt from wiki:

"In 1904 a parish priest in Broome, Western Australia, stated that infanticide was very common, including one case where a four-year-old was "killed and eaten by its mother", who later became a Christian."

I like children very much, but I couldn't eat a whole one. 😉
