Australian Federal Election - Results Thread

[Novelty]

The ALP:



The Coalition:



Just the Liberals in WA, actually.

I've been reading this thread with interest although I'm not Australian.  One thing that jumps out from the maps of Sydney above is the North-South divide of the city between the Coalition and the ALP.  I'm wondering why this is so.  Does it have anything to do with settlement patterns and river drainage geology?

As a Sydney-sider that's easy - the North Shore of Sydney is blue-ribbon Liberal heartland, considerably richer, higher education levels, old-money.

And why should that be?  What's favourable about the North Shore of Sydney that draws the "old money" there?
