Signal Hill Battery

The various Australian colonial governments bought nine such guns and an extra barrel before Federation.

The Signal Hill gun bore Serial Number 7318 and its barrel survives and is on public display at North Fort, North Head, at the Northern end of Australia's Memorial Walk.

The fortifications built in the 1890s around Sydney's eastern suburbs were the culmination of some twenty years of construction of harbour defence installations that reflected the changing policy of the time to meet new technologies, threats and styles of warfare.

The fortification also has an underground complex that runs beneath Old South Head Road.

A memorial was placed there in November 1992 by the Royal Australian Signal Corps Association on behalf of its members.
