a๐ This is just my personal experience since I moved from the Indonesian to the Australian Curriculum in G4, I originally moved to Hurstville PS and I have to say that the culture and vibes from people here is wayyyy different from a typical school in indonesia. Usually kids in AU are more loud and extroverted so if you are a social person its much easier to find new friends ๐. I'm not sure if this applies to you too but the materials were much much easier in AU since I had learnt the same material from a year before so don't worry about not being able to catch up.
