Paying to own content is a big part of Netflix strategy. It takes time to build that up thought. Australia seems like a good example of the challenges trying to pay the owner a fee to show it for some time in some countries.
10 years from now Netflix will have a huge amount of content they own everywhere. It is kind of funny they don't even own the rights to show some of the content they are seen to own in some countries (because they allowed rights to be sold to others in various countries where Netflix didn't operate yet).
It seems like Netflix is either showing restraint about paying to license content in every country or those selling it are not willing to sell it.
And beyond that I do think Uncle Rupert has created extra problems for content in Australia (it seems Australia is the worst Netflix catalogue based on what people say - I haven't actually examined it).
