About Us

Tharwa Sands is a family owned company run by John and Anna Hyles. The company was first established in 1974 and has grown since then into Canberra’s leading supplier of sand and gravel. We produce a large number of landscaping and building products, and customers are able to buy direct from the quarry.

Tharwa Sands is a leading producer of Washed River Sand, Ginninderra Red Granite, Ginninderra Red Ornamental Stone, Washed River Pebble and Topsoil. These products are sold at competitive rates throughout the Canberra, Goulburn, Sydney and Southern Highlands regions.

The Business operates from two Canberra locations,

Tharwa Sands has a long standing commitment to the Canberra, Goulburn, Southern Highlands and Sydney regions with strong ties to over 100 customers including concrete companies, landscape yards, builders, and civil engineers. Our products are used by most of the major institutions such as Parliament House, the National Library, National Museum of Australia, National Zoo and Aquarium, the Canberra Airport and many more. Ginninderra Red Granite is a product exclusive to Tharwa Sands and is seen throughout the public spaces of Canberra providing a natural backdrop to much of the Bush Capital.


The Ginninderra Pit is unique in the fact that the open cut quarry is in the process of being completely reclaimed to its original natural profile due to the importation of VENM and clean fill from the Canberra region. Tharwa Sand uses the natural local grasses and trees to reclaim the site. Tharwa Sand has a strong commitment to the environment with all water testing carried out by Ecowise a NATA accredited company (see annual EPA water test results).

The Tharwa Sand washed sand dredge is located within the high water mark of the Burrinjuck dam on the Murrumbidgee river. The sand is self-replenishing, for every metre dredged the dam can hold another 1000 litres of water. The Tharwa Sand dredge acts as a silt trap for the dam. The deep holes dredged provide an excellent fish habitat at times of low dam levels. NSW Fisheries Programs fisheries research manager Crispin Ashby stated, after extensive examination of the dredge site, “Your dredging has created the best native fish habitat on the Murrumbidgee river”.
