If the hiker determines that the injury is neither life threatening and unlikely to result in any permanent damage, is it unreasonable to activate the PLB?
So in a nutshell: do there exist circumstances where there is an injury that is not life threatening and unlikely to result in any permanent damage, which it would be "reasonable" to pop a PLB? yes of course.
the 8 hours in the example is a bit sketchy - to a car that you can use to drive home? or to a ridge that has reception (that's still XX km from firetrail/transport?)
if your 'walk out speed' is so dramatically reduced due to the injury (and you have been smart and told someone where you are going and when to expect you back) and thus you know there are going to be SAR teams out and about before you get back, then pop it and save everyone the hassle. a few fit guys in their 20/30s might get 24 or more hours 'grace' period before SAR teams start to take the case seriously but if you have kiddies or elderly folks in the group you bet they will take overdue groups very seriously very quickly

gut response: immoblization is a very serious matter and I would never leave someone who is immobilized alone in the bush (if i had a PLB) - i take it we are talking about serious bush here, not 30mins walk to the car/reception. pop the PLB.
if anything is unreasonable in this situation it would be any expectation from emergency services/the public/the media that you should have left your immobilized friend alone in the bush for you to run off and seek help !!
thought response: your immobilized friend has to be extracted from the bush somehow. unless you have 50 buddies around and very pleasant terrain in front of you, your friend's coming out by chopper - may aswell make it sooner rather than later!
I see the confusion here is because of the "Distress beacons should only be used when there is a threat of grave and imminent danger" phrase on the AMSA website (
http://beacons.amsa.gov.au/usage.html) as we all know the bush is a completely different beast to a marine vessel (shelter/resources/equipment/number of personel, etc.) and it's conditions of use should certainly be adjusted accordingly.
I hope whatever response you get from AMSA takes this into account but regardless of what they say, slow down and THINK using common sense first
