I today took some more pictures, here is North Sydney, essentially Sydney's second downtown, on the northern side of the Harbour just over the Harbour Bridge. It is a centre of high tech industry, with offices for Cisco, IBM and others.
Here's the Warringah Freeway, takes you over the Bridge into the city, North Sydney is besides it:
North Sydney Streets:
The North Sydney war memorial, it reads 'Greater love hath no man than this that he give life for the life of his country. Lest we forget.'
