As of 15 September 2014, the laboratory diagnostic results from the National Animal Health Laboratory (NAHL) have revealed that a poultry farm where were introduced one-day-old chicken and ducks was positive for H5N6 as confirmed by real-time PCR. It is now planned to send the positive samples to the Australian Animal Health Laboratory for sequencing.
