I carefully check the label and try to only buy Australian made 100% food.
I never buy any food ever from China.
In Australia, tea and spices are imported predominantly from Asian countries.
Does that meaningfully restrict which foods / ingredients you can get?
It's one of the richest food cultures in the world. If you've never tried sichuan peppercorn on mapo tofu, or pickled mustard greens on noodle dishes, I think you're in for a real treat.
These do involve foods from China though..
