Bluey is a fantastic show, and the fact that it's unapologetically Australian is part of what's so fun about it. I think it's just the choice of nervous higher-ups to localize things like this, and not actually what people want. Like Douglas Adams says, people can survive hearing references they don't understand. And they might even learn something about another culture.
My kids (ages 6 and 3) LOVE Bluey. We are American and (sadly) English-only speakers. The fact that the show is full of Australian accents has not impacted their ability to understand or enjoy the show in any way at all. The exposure to places that are not-America is good for them!
