Just for clarification:
EPIRBs are generally used for maritime incidents. They float, can be activated manually but automatically activate when they enter the water.
PLBs are Personal Locator Beacons. Similar to an EPIRB except they are usually smaller, less expensive, and most do not float.
ELTs are used for aircraft related incidents.
They all perform the same function which is to alert rescuers to the location of the beacon. For terrestrial use it is generally recommended (required?) that you use a PLB.
The system is expensive to maintain since (unless you are abusing the system) the search and rescue usually comes at no cost to the beacon owner. Because of this, you should really only use these devices in situations that may involve the loss of life or limb. Running out of gas on a remote Australian road is not necessarily an emergency. There may be help nearby or other vehicles that may come along within a relatively short time frame. The beacon should only be used if you think that there is a good chance you will end up dead or permanently disabled as a result of your situation.
Of course, one would hope that if you have the presence of mind to carry a locator beacon that you would also make sure to fill up your gas tank before a long trip into an unfamiliar, remote area.
