Well, that "somebody" either hasn’t done their homework, doesn't know what they are talking about, are feeding you a furfy, or using you for a wind up:
Name:
TRANS AUSTRALIA AIRLINES PTY LTD
ACN: 092 564 040
Type: Australian Proprietary Company Limited by shares
Status: Registered
Office: Mount Macedon VIC 3441
Name:
AUSTRALIAN NATIONAL AIRWAYS PTY LTD
ACN: 081 197 944
Type: Australian Proprietary Company Limited by shares
Status: Registered
Office: Darling Point NSW 2027
Cause those names aren’t available and I doubt they would ever be available.
Nice try at a wind up, but!
