The ATSB reports that: "Based upon radio communications, Air Traffic Control (ATC) grew concerned that the pilot may be suffering the effects of hypoxia. ATC advised the pilot to go onto oxygen and cleared the aircraft to descend. The aircraft subsequently landed safely."
As part of the investigation, the ATSB will gather information from the aircraft operator and the pilot. A report will be released within several months.
