At the ring pier in Sydney Harbour, one of Sydney's important public transport. Sydney's bus system includes buses, rail transit and ferry. The pier is divided into six gates and can be swiped with an Australian treasure card. Each gate is like a platform, corresponding to a ferry. Go to different places, take a good look and then sit, don't take the wrong seat. If you take City Rail, get off at Circular Quay. There are many seaports in Sydney's urban area. It is more convenient to take a ferry between the ports in the city and you can also watch the scenery by the way.
