Stuart, Google Maps has a problem with a lot of locations. You'll notice that it puts the ANBG at Hackett and all the reserves along William Hovell Drive (Aranda, Mt Painter, and the Pinnacle) in Dunlop. Sometimes it will add the name of the reserve and sometimes simply place the location as Dunlop. Very frustrating.
Frustrating, misleading (as Stuart has demonstrated) and very confusing!! Not all Mt Painter sightings are in Dunlop - they can just as easily be in Cook or Belconnen.
