We are thrilled to announce the successful completion of a monumental project at Hunter Quarries, where we played a pivotal role in supplying 170,000 tonnes to our major customer, Downer EDI Works Pty Ltd, for the Williamtown RAAF and Newcastle Airport runway upgrade!

Project Scope:

Our objective was to produce 200,000 tonnes of asphalt aggregates to meet the tightly specified GHD airport runway specifications. The materials supplied included Barmac Manufactured Sand (BMS) as well as premium asphalt in 7mm, 10mm, 14mm, and 20mm sizes to fulfill the project’s AC14 and AC20 mix design requirements.

Key Achievements:
  1. Swift Plant Mobilisation: Reacting to project demands, we successfully mobilised a mothballed plant within just one month, showcasing our agility in meeting tight timelines.
  2. Infrastructure Upgrades: Significant electrical and structural enhancements were made to increase plant capacity, ensuring efficiency in production and delivery.
  3. Efficient Workforce Mobilisation: Despite short lead times, our workforce was mobilised promptly to guarantee the on-time delivery of all products meeting project specifications.
  4. Zero Non-Conformance Reports (NCRs): A testament to our commitment to quality, there have been no significant non-conformance reports to date, underscoring our dedication to excellence.
  5. Collaborative Testing: Leveraging the synergies within the Hunter Construction Group, our materials underwent comprehensive testing by Hunter Civilab, contributing to the project’s success with minimal lead times.
Runway Upgrades:
  • The undertaking involved the reconstruction of Runway 12/30 pavement at Newcastle Airport. The previous runway measured 3,500m x 45m wide, and Downer’s team integrated 7.5m wide shoulders to enhance its capabilities. Notably, all extension and reconstruction activities were carried out diligently during nightly curfew hours, ensuring minimal disruption to Defence operations and local access to the Hunter region.
  • The airfield has now been upgraded to accommodate Code E aircraft, such as Boeing 777 and Airbus A350. This monumental upgrade opens up Newcastle Airport to direct international flights to Asia & the Pacific, marking a significant advancement in regional connectivity.

The successful completion of this project not only elevates the infrastructure at Newcastle Airport but also contributes to the region’s economic growth by fostering international connectivity. Hunter Quarries remains committed to playing a pivotal role in projects that enhance community well-being and regional development.


Special thanks to our valued customer, Downer EDI Works Pty Ltd, for entrusting us with this critical project. Kudos to the entire Hunter Quarries team for their dedication, as well as our collaborators, stakeholders, and the Williamtown RAAF and Newcastle Airport authorities.
