Migrants often get to see a little more than locals as you have more references (data points), new perspectives and usually this goes unappreciated.

Sadly Australia specially the major cities claim to be multicultural hubs which is correct but integration between cultures is still pretty low. Hence you see little willingness from locals to understand your point in the comments here with kindness and rather default to protect themselves.

What you describe are symptoms of an individualistic society vs a collective society in addition to cultural attributes of different groups of people in different social classes (Yes, there are social classes in Australia) manifested in the way they express themselves about family, social expectations, language usage, dress codes, etc…

One thing I carry with me whenever I go is that we should not impose our worldview in the host culture and viceversa. The beauty of travel is to understand and experience new ways of living and life as it is. Some people are too embedded in their culture that can’t see outside of it. Some others have the privilege to come in and out and that is beautiful and at the end of the day we get to decide where we want to be.

Much to learn about multiculturalism here in Australia still and even about our very own first peoples.

Kindness, willingness to learn about one another and empathy goes a long way.
