About Us

Western Quarries has been turning dirt to create a long term sustainable quarrying operation since 2015. Our inaugural blast was conducted on the 30th of September 2015, with crushing activities following immediately after. 


As Australian road networks continue to grow, develop and require maintenance, Western Quarries noticed a gap in the market for high-quality aggregate in regional Victoria. Therefore, we seek to be a part of the solution – forecasting and fulfilling supply shortages by sourcing geological products to suit economic needs.


We’re the only quarry that has a certified NATA laboratory on-site, which not only enhances quality control but also enables product production at the point of manufacture. Not only that, but our on-site laboratory gives us the ability to get a quick turnaround of test results and, therefore, be agile in our extraction process.


Western Quarries has delivered 100,000 tonnes of railway ballast, participated in delivering the largest wind farms in Victoria and has supplied products to support major road infrastructure projects from Mildura, Mt. Gambier to Melbourne.
