Your survey is really good. Campsie is cost-effective, with convenient shopping and transportation, and good public security. It is not the best or the area with concentrated shooting.

Hurstville and Burwood are areas where there are many Chinese. Chinese people don't make trouble, which is relatively safe, with convenient transportation and delicious food everywhere.

I don't think it's necessary for you to consider public security now. If you are thin, don't go out alone at night, and take the train in a crowded carriage. These are the most basic ways to protect yourself. If you are still afraid, you can buy small alarms and self-defense sticks in China and bring them here.

as to whether to live in a high-priced area or a low-priced area, it depends on your financial ability. don't force it. to tell the truth, it's neither better nor worse.
