I've been a controller for over 23 years and I've never heard of such a
procedure.

Interesting how things are done differently in different countries. Here is
a reply from an Australian controller from this same thread I posted in
aus.aviation.

Crash,
Mostly right - advise ATC what you have seen. We will ask a few
questions to get as much info as we can. This will be passed to AUSSAR
in Canberra who organise search and rescue. It can be helpful if you can
remain in the area.
If we have an in flight emergency, we will ask suitable aircraft if they
are able to divert to provide assistance. The Operations Director in
Brisbane or Melbourne centre is authorised to requisition aircraft,
however, we prefer to ask than direct. Most pilots we ask are only too
happy to help, as it could be them one day needing assistance. Costs
incurred in either case will be paid by Airservices or AUSSAR.
