  The traditional cultures of Aboriginal Australians include a significant
astronomical component, perpetuated through oral tradition, ceremony, and art.
This astronomical component includes a deep understanding of the motion of
objects in the sky, and this knowledge was used for practical purposes, such as
constructing calendars. There is also evidence that traditional Aboriginal
Australians made careful records and measurements of cyclical phenomena, paid
careful attention to unexpected phenomena such as eclipses and meteorite
impacts, and could determine the cardinal points to an accuracy of a few
degrees.
