Australian National Airlines Ltd

 Australian National Airways, Ltd. (ANA) was a short-lived Australian airline, founded on 3 January 1929 by Charles Kingsford Smith and Charles Ulm.
ANA began scheduled services on 1 January 1930. It owned five Avro 618 Tens, that were British license-built versions of Kingsford Smith and Ulm's famous Fokker VII/3m Southern Cross, which also flew as an ANA aircraft although was not owned by it.
 

 Late in 1931 ANA attempted to open an Australia-England airmail service with a special Christmas airmail flight that was interrupted by the crash of VH-UNA Southern Sun in Malaya. After lengthy efforts to interest the Australian Government in subsidising a regular Australia-UK airmail service failed, ANA went into voluntary liquidation in April 1933, and its remaining assets were sold off.
