If the aircraft landed and blocked the runway I would definitely say LM is isolated. It's at least a 2 hour drive from Carnarvon which has a small runway really. It's about 2.5hours from OLW which is probably the closest larger runway, or 5 hours from KA. KA has the only ARFF in the area unless the military happen to be there (they aren't at the moment). Otherwise Exmouth would be volunteer Firefighters. The town is much smaller than KA so at best they have 2 trucks would be my guess. The hospital is tiny so other than the physical dimensions of the place it doesn't tick many other boxes.
Admittedly PC12's and the like could get into EXM strip but still.
The only thing they have in bucket loads is accommodation, but that may be difficult this time of the year.
