The third point effects the second point. Our TV networks are absolutely crap. They only ever develop reality TV shows, the bottom of the barrel being "Celebrity Splash" (z-grade celebrities dived into a pool); they never show series in order, they interrupt series with something irrelevant, and they show a LOT of ads. Their news is even more atrocious.

Its a badly kept secret that their overall audiences have been shrinking, which is why they only ever give ratings in terms of percentages. A large percentage of a shrinking market is ok, until of course the market gets below a certain size.

Note this does not include the ABC, which is government funded. That network takes risks, always shows series in order, and even has a great streaming service.

I think another major one is the cost and quality of our broadband networks. It's expensive here to download movies, or even to have a connection that's good enough to stream.
