If you are interested in Flying Boats you may like to read a book by Alexander Frater called 'Beyond The Blue Horizon' - (On the Track of Imperial Airways).
Frater is an Australian who, as a child flew several times between Sydney and Fiji. In later years he replicated the flying boat journey from the UK to Australia, flying via modern aircraft but following as closely as possible the original route and going into some detail about how it used to be. I found it very hard to put down.
You will be able to find it by going to:

They are currently listing a bookshop called Klanhorn, in Queanbeyan, NSW as having a copy at A$25.50.
Hope this helps.
