The law and order is still good. Before I came to Perth, I was also worried about the bad law and order. When I came, I found it was actually good, especially after 5 o'clock in this city, all the shops are closed, and you have nowhere to go at night. One of my classmates works until 11 o'clock every day, and it's okay to come back by train alone. But if you are worried, just try not to go out alone in the middle of the night.
