My mistake, but I had the documents for my Visa but did not realise that I had to submit my sister's itinerary, and her accommodation details in Shanghai. We will be staying together, but she will go back to Adelaide and I will go on to Shaoxing. So it was back to the Visa processing office again, collecting mine and submitting her documents again.
As it turns out on this occasion I had two grand children with me - so as they were bored to bits by the long train journey, and waiting (albeit a short time) at the Visa office, I chose to take them to the Brisbane Town Hall Museum.
For anyone visiting Brisbane - this is a great museum with interactive and other items. Well worth the visit.
