Mathematics can become stalled in one particular culture. If we don't continue to look afar, and and embrace other traditions, then mathematics will stall. Two simple examples is the concept of zero, which the Pythagorians detested, and Indian mathematians embraced, and this is all attributed to cultural differences. The other example of Roman numerals, vs Arabic numerals. Again, cultural values around the the role of interest on loans played a large role here.
So very happy to disagree with your take. All countries have issues, and for Australia, this is not one of them.
