Mt Cotton Quarry


What’s happening at the quarry

Owner and operator of Mt Cotton Quarry, Barro Group, is conducting the first stage of an approved quarry extension.

Extending the quarry over time will help our local economy and community continue to grow. Stage 1 involves replacing the previous extraction area with a 15-hectare quarry zone.

Barro Group received development approval for the extension of Mt Cotton Quarry, with conditions, in 2013. Following several approved changes to the development timeframe, works to enable the first stage of the extension began in 2023.

Mt Cotton Quarry has been part of the Mt Cotton community since the 1960s.

Our hard rock quarry produces up to one million tonnes of products per year depending on customer demand. Quarry products include aggregates, road base, rail ballast, drainage media, gravels, sand, fill and Pronto Concrete brand premixed concrete.

These products are the raw materials for constructing roads, land subdivisions, buildings and other infrastructure projects around south east Queensland and northern New South Wales. Local projects like Mt Cotton State School, Redland Bay Fire Station and Cleveland Showgrounds were built using products from the quarry.

Mt Cotton Quarry is owned and operated by family-owned Australian company Barro Group. The company has been a supplier of construction materials and services to the development industry since 1946. Barro Group purchased Mt Cotton Quarry in 1992.
