So you know how some people live in different parts of the world, right? Well, some of those people are from a really big country called Australia, and they've been living in a city called Hong Kong for a long time.
Hong Kong used to be a part of another big country called China, but now it's its own special place with its own government and way of doing things. The Australians who live there are just like the people who live in Australia, but they've made their homes and families and jobs in Hong Kong.
Sometimes, things happen in Hong Kong that make the Australians who live there worried or uncomfortable. They might hear about protests or other things going on in the city, and they might feel like things could become dangerous. When that happens, they might decide to leave Hong Kong and go back home to Australia until they feel like it's safe to come back.
It can be really tough for people to have to leave their homes and lives behind, but sometimes it's the best thing to do to stay safe. So the Australians in Hong Kong are just trying to find balance between living their lives and taking care of themselves, just like anyone else would do.
