1A,
Interesting little note at the bottom of that site, given the "Virgin Australia" trademark appears to be owned by an entity sharing a UK address with a plethora of other "Virgin" entities:
Public Notice: VIRGIN AUSTRALIA PTY. LTD. ACN; 051117401 is an Australian owned company, founded in March 1991 in accordance with all Australian Government and Corporate Laws. Virgin Australia wishes to make it clear, that it does not want to be confused or associated with Sir Richard Branson’s - Virgin group of companies.
