Practice Relating to Rule 54. Attacks against Objects Indispensable to the Survival of the Civilian Population
Section B. Attacks against objects used to sustain or support the adverse party
Australia’s Defence Force Manual (1994) states:
710. Foodstuffs and agricultural areas producing them, crops, livestock and supplies of drinking water intended for the sole use of the armed forces may be attacked and destroyed. Extreme care will need to be exercised when making some objectives a military target, eg drinking water installations, as such objects are hardly likely to be used solely for the benefit of armed forces.
711. When objects are used for a purpose other than sustenance of members of the armed forces and such use is in direct support of military action, attack on such objects is lawful unless that action can be expected to leave the civilian population with such inadequate food or water as to cause its starvation or force its movement.

Australia’s LOAC Manual (2006) states:
7.11 Foodstuffs and agricultural areas producing them, crops, livestock and supplies of drinking water intended for the sole use of the armed forces may be attacked and destroyed. Extreme care will need to be exercised when making some objectives a military target, eg drinking water installations, as such objects are likely not used solely for the benefit of armed forces.
7.12 When objects are used for a purpose other than sustenance of members of the armed forces but such use is in direct support of military action, attack on such objects is lawful unless that action can be expected to leave the civilian population with such inadequate food or water as to cause its starvation or force its movement.
