Griffo,
The new airport is 'Pudong' (PVG/ZSPG).
The Maglev is a fun ride, but it's only 8 mins and then you still have to get into town by the subway.
Imagine building an airport at Richmond and having the Maglev take you in as far as Strathfield.
Hence it's probably a taste of the future, but to be honest, a bit of a hassle given the need to change transport modes at the station in the 'burbs; so I reckon it's more of a novelty than useful RPT at the moment. But, do it so you can say you've done it and it is cheap is A$ terms.
But
Knox I agree with
Griffo that you should enjoy your trip, it is an amazing place. Especially some of the
signs translated into English...
