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.
