We are Australian, arriving by cruise ship in Shanghai port for a two day stay in March.

We hope to take a shore excursion on each day. The next port of call is in South Korea, then back to China, to Xingang port for another two day stay. Once again we hope to go ashore both days. Does anyone have an indication of what we require in the way of visas? The online information is quite confusing. Do we require double or multiple entry one?
