Why Are Aussies Such Pussies When It Come to Tom Cruise?

Andrew Morton's unauthorized Tom Cruise biography, in which the aging idol's creepiness is given full voice, has been made unavailable in one of the Planet Earth's seven continents. The book's importers in Australia, reports the Sydney Morning Herald have decided not to import the book after all.
US-based Ingram International, described on its website as "the world's largest wholesale distributor of book product", sent an email to its Australian customers this morning citing unspecified legal reasons for not being able to distribute the book outside the US and Canada.
"Although I recently e-mailed stating Ingram's ability to offer the book to international customers, the position has now changed that we will not sell it outside of the US and Canada," Asia, Australia and New Zealand sales representative Jonathan Tuseth wrote in the email.
Unspecified legal reasons? Isn't that the whole reason Australia was settled in the first place?
