Here you go, these are the 2 main plugs you will need, get them from Travel/Department stores brands are Korjo or Go Travel.
I travel to China lots (going again tomorrow night) and you will see "Australian" type plugs main up north Shanghai and above but will find your plugs do not quite fit. so take these adapters.
Thanks Guys, you've confirmed what I read elsewhere...our Austalian plugs may work...but not necessarily...I'll scoop an adaptors if I see any just in case...
