I'll start!
3RF are holding a "Post-Eclipse Star Safari" at Coonabarabran. Obviously Coona is not near Cairns so you'll still need to get yourself down to Coona after the eclipse (allow a few days travelling time unless you fly).
3RF are well known for hosting US and overseas visitors for their star parties in Coona.
