Narrative:
Crew oxygen supply depleted while en route. Flight abc clt to aua. Situation discovered by captain when first officer elected to leave cockpit to use restroom prior to landing at aua. Before he exited cockpit, captain attempted to don oxygen mask. No oxygen available. Pressed 'doors' page on ECAM system and discovered oxygen supply zero. Obviously, very serious. First officer called for 2 portable oxygen bottles to be brought forward to the cockpit from cabin. Closest suitable airport in time was determined to be aua, so descent initiated and landing accomplished. Cause of depletion of oxygen supply undetermined by flight crew.
