Australia’s Defence Force Manual (1994) states:
All reasonable precautions must be taken to avoid injury, loss or damage to civilians and civilian objects and locations. It is therefore important to obtain accurate intelligence before mounting an attack.

The same principles apply to the risk of damage or injury to any other protected persons, places and objects.
