Canada has gone through a great deal of pain to ensure that the Canadian music scene and "Canadian Culture" survives vs the cultural onslaught that is living next to the US. There is a highly debated rule in Canada about what is called "Canadian Content" and that of everything broadcast - be it on the radio, television, etc - a certain percentage of it must be considered "Canadian." It's contentious. Sometimes leads to hilarious results, such as an extra 30 minute news cast every day which constituted "Canadian."
Does Australia have anything like that?
We have quotas on TV that have to be Australian content the same as Canada, but we have content from all over the world really, the UK and Canada, Europe, also the US of course. News services, current affairs and seeies also. I never watch free to air television though, I only watch PayTV and streaming services, (documentaries, movies and series.) The news is for schmucks.
Australia produces some reasonable content, but also some terrible stuff like "reality shows".
