You don't have to be brain dead in Australia anymore either.. only your heart has to stop.

"Identify cessation of circulation (absence of circulation for a period of not less than 2 minutes and not more than 5 minutes)"

While the plain English information sheet cherry picks some severe cases..

"Generally they are patients with very severe brain injury from which they cannot recover. Less often, they are patients with terminal heart or lung failure, or have suffered a very severe spinal injury where they cannot breathe unassisted"

The actual protocol says...

"resuscitative attempts are either contraindicated on medical grounds, given that it has been determined that meaningful recovery of the patient is unlikely, or the patient (or the person with legal authority to make his or her medical decisions) has decided that resuscitative measures would be unduly burdensome."

Which pretty much gives the green light no matter what.
