I'll answer your question seriousily. Australia is all about multiculturalism and that's what makes this place one of the best countries in the world to live in. We should be able to keep our cultural practices and elements no matter what , but i agree we have to also engage in certain elements in Australia. It's not like i totally ignore the whole idea that im in Australia and an Austalian person. Im 100% proud to be Australian and also enjoy the lifestyle.
Secondly, My korean cultural aspects are influenced from families/friends. This is how i grew up in my household and community. This is why i enjoy speaking Korean and etc.
I hope this answered your Q.
