Country around the board

You have completed the scaled journey. The AAT dome stands for our life-giving star. Here modern astronomy and ancient Kamilaroi sky knowledge meet. The Emu in the Sky stretches across the Milky Way above you.

Where to look

Search Google Maps for the planet plus the road or town. Boards are large, dark blue, and sit on the five approach roads — then Timor Road and Observatory Road for the inner worlds.
