Clontarf Hill Quarry Bush
Around the time of photographing this site in December 2022, I tried to research Clontarf Hill and its role during WW2. There didn’t seem to be much information other than what was published in the Friends of Clontarf Hill documents.
Clontarf Hill in WW2
It’s clear there are remains on Clontarf Hill that appear to have been constructed by army engineers, judging from the looks, size and shape, which are very similar to infrastructure left behind on military sites like Point Peron and Rottnest Island. Of course, many areas in the bush and in old farms could have similar structures but from what I’ve seen so far, these stand out, however subtle that may be.
Between Fremantle and Rockingham, there certainly seemed to be far more army camps, gun emplacements and searchlights than anywhere else along the coast, metro area or in Western Australia.
This could be attributed to the extensive bushland environment that made it suitable for shooting ranges, diverse terrains for training, sparsely populated areas and most importantly, the capability of being able to defend the nearby coast and airspace against potential enemy invaders, whilst still being inside the jurisdiction of Western Command and the Fremantle Fortress.
Cockburn Cement Quarry
This quarry sits on Cockburn Road in Henderson, near Woodman Point, within the City of Cockburn.
It forms part of the industrial corridor that stretches along Cockburn Road between South Fremantle and Henderson, an area that has been tied to heavy industry for decades.
The quarry was historically associated with Cockburn Cement, one of Western Australia’s major cement and lime producers. Operations in the wider Cockburn industrial area date back to the mid-20th century, when large limestone deposits along the coast were developed to support cement manufacturing.
Limestone is a key ingredient in cement production. It is quarried, crushed and then heated in kilns at extremely high temperatures to produce clinker (a hardened material), which is later ground into cement powder. Western Australia’s coastal limestone formations made the region around Cockburn Sound an ideal location for this type of industry.
The Henderson quarry site itself is one of a number of extraction areas that supplied raw material for these operations. From there, the limestone could be transported to nearby processing facilities.
Today the surrounding area is dominated by heavy industry, shipbuilding and port-related activities, particularly around the Australian Marine Complex further south at Henderson. Like many industrial extraction sites near the coast, the landscape has been heavily modified over time. Quarrying removes large volumes of limestone, leaving stepped excavation faces and cleared ground where the original coastal terrain once sat.
