A young man gets lost in the bush, but he has a lifeline: a mobile phone

There's an opportunity here to come up with a system that works.

The report of the coroner's findings is at:

degeneracy in systems, processes and management.

 From my own experience in dealing with the public, people don't 
necessarily know what they need. Much of the skill in working the phones 
lies in extracting enough information from the caller to solve the 
problem, rather than just answer their question. Expecting someone who 
may be distressed and disoriented to make a decision about what they 
need is a recipe for disaster.

That's quite a comment on the information systems involved.

So: there was flexibility in the system to override its demand for a 
street address, but the operators either didn't know how to use it or 
were trained not to.

The system gives the address. To do that, it must identify the phone. 
They have a phone number to act as record identifier, but the Ambulance 
system demanded a street address. Recording the phone number would at 
least identify repeat calls, but the system wasn't set up to do that.

How could such an archaism persist into the 21st century?

Recommendation 1
That a working party (including the NSW Ambulance Service, NSW Police 
Service,
NSW Fire Brigade, NSW National Parks and Wildlife and Telstra Communications
Service Point) be established to review the structure, operation, 
management and
training for NSW triple 0 emergency call centres, with particular 
attention given to the
following issues identified in the course of this inquest:
...

Probably relates to

If my life was hanging in the balance, I don't think I'd be much 
comforted by the knowledge that the person who answered my call for help 
might have been on duty for a half-day. Nobody who's ever done a lick of 
work would think that a 12 hour shift is a good idea, yet they're 
favoured these days (even in environments as dangerous as mines). Once, 
when puzzling over management behaviour, I was told that it sometimes 
helps to to regard management as a form of mental illness. I find those 
times becoming increasingly frequent.

Whoever is charged to update the Triple-0 dinosaur needs all the help 
they can get.
