If you have a look at the site I linked to (Emu dreaming) and click on some of the images on the right, you'll see information about awareness of the Sun, moon and eclipses, ceremonies related to Venus, the emu-in-the sky constellation, a 50 metre stone circle in Victoria which appears to be aligned on the equinox and solstice sunsets, and a possible lunar calendar etched into rock in South Australia.
