Two-thirds of media vendors in Australia are pirates
I don't know if they looked at what media companies - producers of books, music, movies, video games etc have been getting away with in Australia for years.
Even with the AUD at parity with the USD, iTunes charges up to 65% more than it does its US customers, paperback books are the cost of hardback in the UK and US, a visit to any suburban cinema costs more than going to a central London theatre. Many alternate online purchase vendors (Amazon etc) do not sell to that part of the world, and I wouldn't say that the ones who do are well-stocked. That includes iTunes - plenty of UK and US material is not available there at all.
The commercial TV networks have been making it impossible to watch or follow most overseas series because of the way they play with the timetables or in fact just discard a series altogether. Finally because Australia and NZ are region 4 for DVDs all sorts of pricing and release-date atrocities are inflicted on the local market, so everyone has a regionfree player and imports what they can afford postage-wise. When you see region-4 NTSC DVDs dumped in Australia you can see that the video vendors are hardly taking the market seriously.
As a result I think most Aussies have leapt at the only consistent avenue of supply available given the contempt and greed of suppliers.
I'm sure that if BBC iPlayer were made available for subscription in Oz that it would be popular. BBC may do that but they're only going after the US iPad-owner market now.
