The top image shows what a bus in Sydney looks like and the bottom image shows the inside of a bus in Fukuoka, Japan. They look similar but they're quite different. In Fukuoka people go on the bus by the back door and get off by the front door where they pay their fares. This is the opposite in Sydney - people go on the bus through the front door and pay first. When you get off, you can get off from either doors.
The buses here don't stop at all stops and they only stop when someone presses the "stop" button. As well as that there aren't any announcements that tell you what the next stop is, so make sure you know where you need to get off or ask the driver if you are unsure.
When you are waiting at the bus stop and you see your bus approaching, make sure you wave at the bus for it to stop otherwise it may not stop for you!
One final difference is that Sydney buses aren't as reliable as buses in Japan...
