The Boral Wollert Quarry was established in 1971 as a hard rock quarry. Together with its processing operations and concrete plant it occupies approximately 178 hectares of Boral’s land holdings.
West of the quarry pit, Boral operates a quarry processing plant and concrete batching plant.
These aggregates provide the base material to produce concrete, asphalt and other items commonly used in building and construction applications.
The quarry's relatively close location in relation to the Melbourne CBD has allowed it to make a substantial contribution to the city's skyline over time.
The processing of stone and delivery of rock products to and from the site may occur between the hours of 6am to 6pm Monday to Saturday.
Today's operations employ 14 full time staff and supply work for up to 40 transport drivers. Resource
The Boral Wollert Quarry lies within the Morang Hills, described in geological terms as a Palaeozoic Inlier (area of older rock enclosed by younger rock) surrounded by basalt flows.
The Inlier consists of a Devonian Granodiorite with an outer aureole of metamorphosed Silurian sediments (hornfels).
Differential weathering resulted in these more resistant rocks forming the Morang Hills, meaning flows from the subsequent period of volcanism failed to cover these areas.
The quarry is located on the south western slopes of the most southerly of the Morang Hills and it is the metamorphosed hornfels and weathered hornfels that are quarried.
The hornfels forms part of a sequence of fine grained Silurian sediments comprised principally of mudstones, shales, siltstones and sandstones.
These sediments have been subjected to thermal metamorphism due to the intrusion of a large granodiorite pluton.

Positive relationships with the community are an important part of conducting our business activities.

Boral Wollert Quarry Environmental Review Committee (ERC)
To help facilitate ongoing communication with neighbours and other local stakeholders, the Boral Wollert Quarry operates an Environmental Review Committee (ERC).
The ERC meets regularly to examine the quarry's environmental performance. It provides a forum for issues to be raised and discussed in connection with the operations.
You can request the notes from meetings by emailing Community feedback.
The Wollert Quarry satisfies its obligations under Work Authority 102 for environmental emissions. Quarries, by nature, generate dust, noise and heavy vehicle movements. Activities are monitored by Boral and mitigated to acceptable standards within prescribed approval limits.
Minimising resource use
There are a number of measures in place at the Boral Wollert Operations which are designed to ensure use of natural resources is kept to a minimum.
Water conservation - The quarry uses water from two on-site bores for production purposes. Mains water is only used for amenities. A Water Conservation Plan has been devised for the operation which has helped keep water usage very low - each tonne of aggregate produced requires only 0.04 litres of water use.
Dust emission management - active dust suppression measures concentrated on dust sources are in place at the quarry (as well as the other sites).
A water cart is in regular use on the site to keep dust emissions down on internal roads. Parts of the plant have sprays installed to also minimise dust escape.
General operating approvals
The Boral Wollert Quarry was established in May 1971. The quarry was followed by the Concrete plant (2004).
The quarry's main approval is Extractive Industry Work Authority 102 (WA102), issued under the Mineral Resources (Sustainable Development) Act 1990. This allows the operation of extractive activities at the site.
WA102 is supported by Planning Permit 704899, issued by City of Whittlesea, which provides planning permission to operate the quarry. This permit is itself a requirement of WA102.
The concrete plant, which sits adjacent to the quarry has been excised from the Quarry’s work authority (WA102) and operates under its own planning permit 707573 from the City of Whittlesea.
