Looks like Peterc005 and CB Hunter may win the ribbon for this one, just having a look at the ATSB website and the Investigation is now titled "Fuel starvation and forced landing involving PA31, VH-OFF near Aldinga ALA, South Australia on 29 January 2014".
Might be a timely reminder for all those flying Chieftains and Navajos and the many other aircraft that susceptible to this kind of simple error around the country to be extra diligent, be safe out there boys and girls!!
