Sand is among the most used materials in construction, with its usage often determining the strength and durability of the resulting structure.
Our Queensland Sand and Stone supply business supports the regional Housing Industry, for the building and development of quality housing for an increasing State population.
Coonambula Resources Group Pty Ltd concentrates on the construction industry which is one of the largest industries in the world, and sand is a major contributor in everything to do with construction materials. More than 50 billion tonnes of sand is used in construction globally, annually.
We are aware that Sand can be easily compressed and, in some cases, can be very malleable. This is the perfect ingredient for creating building components and foundations.
- Plaster sand
- Building sand
- Crushed stone
- River sand
- Bedding sand
Our Permit provides for our lawful extraction of millions of tonnes of Coonambula Building Sand and Decorative Stone for landscaping and other uses.
Washed Pit Sand is used for concrete batching and Brickies Loam is used for brick and blocklaying, etc. We hold a current Permit No. 175-09 issued in 2011 by the North Burnett Shire Council to extract Sand and Stone from the Quarry called “Coonambula” residing on a Cattle Station of that name.
Sand is essentially made from rocks that have been broken up and eroded over time and ground down to form much smaller particles. One of the primary ingredients of sand is silica. This is a naturally occurring material that is found in nearly a quarter of the Earth’s crust.
We have spent considerable time and millions of dollars researching and developing an environmental plan which includes our reclamation of quarry land and Carbon (CO2) Sequestration.
Our Sand Testing
We have established the importance of high-quality Sand to the Construction Industry. There are a number of type of Sand for Builders to choose from for project requirements and we have and continue to conduct testing of our Quarry Sand for the domestic and international markets we have identified: –
To detect impurities in the Sand, we have conducted testing with caustic soda or sodium hydroxide.
To detect Clay, which will affect the Sands binding properties, we place the sand in transparent testing jars and the container is shaken and allowed to settle. A distinct layer will form atop the sand if clay is present.
To detect Salt, we use the age old “human taste test”. A high salt content may have long-term building issues.
“We have taken every precaution through our sampling and testing to ensure the highest possible quality of the extracted material we quarry from our permitted land at Coonambula.”

How Do We Quarry Sand
We have spent some years in preparation of utilizing our heavy equipment to extract thousands of tonnes of sand to the domestic and international markets. We are permitted to quarry by local government.
What Are Our Markets
The Australian domestic construction and landscaping industries are by far our biggest markets. We have received strong demand from countries such as Singapore that have had to resort to manufactured sand.
Building & Construction
Without Sand, the construction Industry would have severe shortcomings in the ability to build homes and commercial structures. Sand forms a base for many building products, primarily, sand fill, mortar and concrete.
