Australian troops are required to take fingerprints and eye scans of very insurgent they kill, if it is possible to do so. Troops are equipped to conduct these investigations in the field. The information is then compared to a growing national biometric data base of insurgent suspects in an effort to identify them.
ABC did not report why the hands were not fingerprinted at the scene of the battle.
The report said that an investigator from the Australian Defense Force Investigative Service a branch of the military told troops during a briefing that it didn't matter how the fingerprints were taken and that chopping off the hands of the dead and bringing them back to base was acceptable.
The mutilation or mistreatment of dead bodies can be a violation of the laws of war.
John Blaxland, a researcher at Australian National University's Strategic and Defense Studies Center, said if the allegations were true, the behavior was an aberration of the high standards the Australian military had maintained during more than a decade in Afghanistan. Blaxland said it was possible that a "temporary exception" from procedures had been allowed in the case of "a high value target."
Defense analyst Allan Behm said such a "direction would have to be cleared at the very highest levels." He said the allegations amounted to prima facie case of a breach of the rules of law.
Neil James, executive director of the Australian Defense Association, an influential security think-tank, said the alleged actions might have been justified by the circumstances and that it shouldn't be equated with the 2011 case of a group of U.S. Marines urinating on the bodies of dead Taliban fighters.
"If it occurred, it would be unusual. It would not necessarily be illegal," James told ABC.
Australia has 1,550 troops in Afghanistan and is the biggest contributing country outside NATO. Australia has contributed the largest number of elite special forces to the campaign after the United States and Britain.
Prime Minister Kevin Rudd said he had confidence in Defense Force Chief Lt. Gen. David Hurley to investigate the allegations.
