Mt Coot-tha Quarry

The Mt Coot-tha Quarry has served the residents of Brisbane for over 100 years. In the mid-1890s, Mt Coot-tha Quarry was established by Toowong Shire Council, as one of Brisbane’s first major quarries, providing stone (including aggregates) to build some of our city’s earliest infrastructure.

The quarry has been operated by Brisbane City Council since Council’s formation in 1926.

The materials quarried at Mt Coot-tha are metamorphic rock, formed when fused by molten heat. This process has created strong hornfels deposits which require blasting to fracture. The strength of this material adds to its value in the manufacture of durable, long-lasting asphalt products – well suited for Council’s 5800-kilometre road network.

Mt Coot-tha Quarry’s use

The quarry is an important strategic asset for Brisbane city, supplying localised, cost-effective, high-quality asphalt aggregate to build the roads and infrastructure our growing city needs. It is for this reason, Mt Coot-tha Quarry has been designated a Key Resource Area and is protected by the State Government as a significant state resource.

Currently, over 96% of roads in Brisbane are built with asphalt aggregates from Mt Coot-tha Quarry. The quarry itself sits on approximately 26 hectares and produces approximately 400,000 tonnes of asphalt aggregate each year.

Council’s quarry operations

Mt Coot-tha Quarry supplies asphalt aggregates to support Council's asphalt production and road surfacing programs, while Council’s Bracalba Quarry is dedicated to civil construction materials and aggregates.

Regulation and oversight

Mt Coot-tha Quarry has a long history of environmental compliance and all environmental compliance monitoring is conducted by independent auditors.
