Tourist visa L for visit to Beijing for 4 days between Australia and Europe, and return later?

Then you may just apply for the China tourist visa from the China Embassy in Australia if you live in Canberra District, South Australia or North Territory. If you live in other places of Australia, please go to the right consulate general to apply for the visa.
You have to submit these documents for the visa application, including your valid passport, a fully flled visa application form, round-way air tickets, copies of other ID, e.g. previous passport, driver license if you have not been to China, copies of recent Chinese visa with entry record if you have been to China before.
