Answer 1

This ought to give you a quick start:

It's a review of a book called The Rise of Colonial Nationalism: Australia, New Zealand, Canada and South Africa First Assert Their Nationalities, 1880-1914

Edited by John Eddy and Deryck Schreuder. Sydney, Australia: Allen and Unwin 1988.

That should give you an idea of other places to look.
