Tried to add, but mucked it up, that AUSSAR were very good. They notified NOK and arranged the police to come.
Seem to be at end of the paper chase; ESIR generated by Air Services via CASA and RAA, plus CASA and RAA Incident&Accident Reports.
Cannot express strongly enough value of registered 406, plus the other requirements like water and shelter (I carry space blankets) layed down. Sat phone also very welcome. Also a large amount of luck on having suitable land under you.
Most important however...when in doubt FIRSTLY FLY THE AIRCRAFT!!!
