Hornsby Quarry

Hornsby Shire Council owns Hornsby Quarry, which has an important place in local history and has the potential to play a great role in Hornsby’s future.

April 2019 - Hornsby Quarry Development Application and EIS

NorthConnex finished delivery of fill material to Hornsby Quarry in January 2019 and are now demobilising from the site. Over the last year, Council with consultants prepared and lodged a Development Application (DA) with an  Environmental Impact Statement (EIS) for the next stage of works, to re-shape and stabilise the site, with the aim to deliver a safe landform that can be used for many different parkland activities.

The Development Application and supporting Environmental Impact Statement for the transformation of Hornsby Quarry are now on Public Exhibition until 17 May 2019.

The DA will be determined by the Sydney North Regional Planning Panel before Council can begin the earthworks.

The EIS also includes some important recommendations about how to best protect the natural environment of the site, including the Ecologically Endangered Communities, preserve Aboriginal and non-Aboriginal heritage and manage potential impacts on nearby residents, businesses and the community.

Want to find out more?

The Hornsby Quarry site is set to become the region's premier new parkland. Visit hornsbypark.com.au to find out more about the great ideas that are being proposed and follow the transformation of the site into a wonderful parkland for the community.

What is Hornsby Quarry?

The quarry is located on the western side of Hornsby, very close to the town centre. It is more than 100 metres deep with steep, exposed sides. The site is currently closed because of serious safety concerns and Council is exploring ways to open the site to the public.

Why does Council own it?

The quarry was operated by private businesses from the early 1900s until 2002, when it became unprofitable and Hornsby Shire Council was legally obliged to buy it from CSR Limited. A decision by the Valuer-General meant Council was forced to pay more than $25 million for the site, though Council was able to recover $9 million during later legal proceedings.

Why is Hornsby Quarry special?

The quarry is historically valuable, ecologically important and visually spectacular – all within walking distance of Hornsby’s CBD. It is well-known as the largest volcanic diatreme in the Sydney area. Especially significant is the east face that provides a cross-section of the diatreme, which is seen at only a few sites in the region.The bushland on the site is also significant and includes blue gum high forest, which is listed as an endangered ecological community.

The Higgins family cemetery is also located on the site and is listed as a heritage item of state significance, with burials ranging from 1875 to 1925.

What are Council’s plans for the quarry?

The quarry is being partially filled in to make it safe, using excavated material from the NorthConnex tunnel that is currently being built by the NSW Government to link the M1 and M2 motorways.

Once this is completed Council will begin rehabilitating the site, turning it into a spectacular new open space for recreation and entertainment. These plans are in the early stages and will involve significant community consultation before they are finalised.
