England and Australia have their own separate media.
Which shows tons of American programming.
Also scads of English content, some New Zealand content, a significant proportion of Canadian content and, oddly, even some German content with hyper paced translations to try and keep up with the natural verbosity. Every now and then we might get some Australian content but that is mostly just 'reality' shows where they scrape the best examples the lowest common denom's and put them in front of a camera and wait for the tears. You pick the homonym, both work.
For years, the older generation have complained about this cultural colonisation, and it occurs in part because of the percieved 'Terra nullus' status of Australian culture, percieved that is, by a select set of what most of the rest of the country like to call 'those Sydney wankers' or 'those Melbourne tossers'. sometimes even with affection.
For the rest of us Australians have what we call a 'cultural cringe' which could be seen on any australians face whenever that mad dead bastard Steve Irwin would shove his thumb up some reptiles bottom and exclaim 'crikey!' or 'Strewth' .Luckily these horrific anachronisms have dropped rapidly out of popular use in the last thirty years, I suspect not becuase of cultural colonisation, but because we got tired of being percieved as dickheads.
Although, pretty much all of the content provided by Australians on YouTube would indicate, that, we are, sadly, a nation of dickheads. but bonza dickheads mate.
