I was in Chemist Warehouse (Beaumont St, Newcastle) and saw they now sell quad-copters in their toy section. I'm assuming they are available nationally.
The LH-X1 doesn't have headless mode, but does have a quick swap battery and at 140 x 140 mm, it's much larger, and easier to fly than micro quads.

From a pharmacy? I guess drones and drugs do go together!
