On Apr 11th 2014 the JACC reported that analysis of the signals received by the RAAF AP-3C Orion Aircraft on Apr 10th 2014 identified the signals as being unrelated to the flight or cockpit voice recorders.

"A decision as to when to deploy the Autonomous Underwater Vehicle will be made on advice from experts on board the Ocean Shield and could be some days away."
Seems that's yesterdays ping was another red herring.
