Are there any resources to track Aurora sightings or predicted sightings?

Worth noting that Kp, which many talk about in discussions online, is more or less useless for anyone in Australia or the southern hemisphere. Lots of beginner Aurora chasers here get tripped up by that.

What is useful is KAus and the G index, KAus is shown on this page, so thats what i'll be tracking.

Is that tonight or last night?
