Hi, We are a family of 4 travelling from Frankfurt to Shanghai arriving 07:15 on 10 October 2018

And leaving there for Brisbane at 21:15 on the 16 October 2018. Does this qualify for the 144hr visa (I calculate 135hrs but am concerned about flight delays)? We are all German and Australian citizens. Also, if we do a 4 day tour can we include a boat ride and then add an extra day for Disneyland? We have a 5 year old and 1 year old, so must appeal to kids also.
