It's not quite that simple. The needs and responses of a local market can be completely different from one to the next.
Because of differing cultures, we respond very differently to color palettes, design aesthetics, safety concerns, cool factors, etc. And since the entire point of marketing is to sell, then the the brand's visuals, branding strategy, responses to concerns, etc, all have to be completely customized for the local market in order to engage customers.
For example one common difficulty tech companies often encounter while trying to enter Japan was how difficult it was to acquire and retain users compared to anywhere else. Some gave up, some would keep trying, and surprise—it would magically work out when you hire a local ad team, local designers, art directors, etc. Western companies' sleek, advanced designs are easy to use and navigate, but the locals understand that culturally, the Japanese society resists change. They are used to early day yahoo/geocities level of banner ads and flashing gifs on a page so that they can feel certain that what they are using can be authentically catered to the Japanese people and supported. Overly simple designs like a Bootstrap framework was simply too frightening, new and confusing.
Same can be applied to pretty much anything from fashion, beauty, food, retail of any kind, to things like Uber, which specifically has its own complexities to solve while trying to enter a taxi-efficient market like that; a completely different marketing problem to solve than say Australia's safety concern as you mentioned.
TL;DR: Can't easily centralize marketing because local cultures and needs are always different; and you need locals to know what locals will want/engage with.
In darker moments I always think that eventually, this is an inevitable outcome for someone like me. But as somebody who's also experienced help that worked, even if for only a time, I wish that you (we) can hold on to some hope and trudge on. Maybe life will surprise us and we'll go at it till the end. Good luck.
