Also, note that an activated PLB/EPIRB sets off a major SAR response as "grave and imminent danger" is assumed - this is a bigger deal than calling 000. The satellite alert is passed from AMSA (Canberra) to local SAR authorities. They will check with who the device is registered to (emergency contact/owner) and proceed to a full search and rescue response immediately if they confirm its needed or they can't contact them.
Not quite true, all EPIRB activations are received at RCC/AMSA in Canberra, they assess the validity of the activation, it's location if available and collate that with the registration info (assuming it's registered).
That is combined assessed and in conjunction with state Police a
proportional response is then activated.
for example, an EPIRB activated within an urban area far from the ocean might only result in phone calls to the last registered owner, if determined to be a false, malicious or a stolen activation no assets are deployed.
if an activation is received and the location is out on the water 20 miles off shore, RCC might at the same time deploy air/water assets whilst calling the registered owner and next of kin, if the get confirmation the husband is out deep sea fishing and its 25 knots on a 2m swell the search assets are already on the way, if they get a second ping and triangulate a better location and they have activated the EPIRB accidentally while cleaning the boat at the ramp then no harm done, SAR assets can return to base no dramas.
If an EPIRB pings out bush and its registered to a prospector, air assets might not even be viable in the immediate time frame. A phone call to the local police station might get a vehicle out, alternatively the local coppers might know the station owner the prospector is on and they will go out and get them.
there are too many variables and what-ifs when it comes to search and rescue, none are the same, not even close. If you have an EPIRB register it with AMSA, if you have one and are in the poo, activate it if in doubt. If you abandon your kite or boat and swim in, call someone, Water Police direct is your best option, second option is Police via Triple Zero (But assume you will be talking to someone who doesn't know the difference between a kite and a windsurfing rig, so be nice while they pass the info to someone at Water Police who do know the difference
