I fly in remote areas too. Not as remote as PNG but it is pretty lonely out here.
There have been reports of ELTs not going off in case of a hard landing or worse.
Since I'd like to be found dead or alive in case off a mishap I have mounted a SPOT2 in my aircraft with tracking service activated.
The aircraft is being tracked by the office and selected friends over the internet.
Edit: What is a SPOT?
