HONESTY. QUALITY. INNOVATION.
Gosford Quarries is a large company with a proper family approach. As Australia’s premier supplier, we operate professionally and efficiently in corporate capacities, and our staff treat each client with caring, friendly and reliable service.
Gosford Quarries was founded in 1922, and its first processing plant was in Gosford. At that time, the company was known as ‘The Hawkesbury Sandstone Co.’ The signature sandstone colour range of this era was ‘Gosford Grey.’

Many historical landmarks feature this predominant colour, particularly the Australian War Memorial, hewn and built in the Wondabyne sandstone colour range. This building is of such significance that we have chosen it to present our 100-year Centenary in our Centenary Logo for 2022.

In January 2013, Gosford Quarries merged with Sarkis Bros. Sandstone, bringing together two of Australia’s most revered and experienced sandstone suppliers.
The Sarkis family has a rich heritage in stone, and their father, Antonios, founded a limestone quarry in his homeland of Lebanon in the early 1970s. Stone processing has been an integral part of their life ever since.
Gosford Quarries is now the primary supplier for the largest scale of civil and commercial works in Australia, consulting at the highest end of their market to Civil, commercial, and restoration partners.
Gosford Quarries is known as ‘The Sandstone People’. Generations of employees now treat GQ like their family; they love, work, live, and breathe sandstone.
Gosford Quarries is proud to continue its traditions of quality and commitment to the Australian community, which were established over the 99 preceding years of our Centenary.
“For over 100 years, Gosford Quarries Sandstone has known no equivalent in sandstone supply, in-house masonry & artistry, sandstone processing technologies, in-house draftsman and expert sandstone advice to residential, commercial, and civil & heritage customers and their sandstone projects.”
“In a way, Gosford’s sandstone can be seen as an emblem of Australia’s natural beauty and strength”, writes Aleisha Parr, an Australian journalist.
From the Sydney ‘Yellow Block’ sandstone (quarried on-site in the CBD) to the vast array of architectural sandstone featuring the immortal ‘Hawkesbury’ brown sandstone, made famous by some of the most significant historic architectural landmarks in our major cities, Sydney & Melbourne among them, Gosford Quarries sandstone is immortalised in the skin and bone of both our historic and contemporary buildings.
100 YEARS OF LOCALLY SOURCED & QUARRIED SANDSTONE
100-year-old Gosford Quarries continues to supply sandstone from 8 Quarries throughout NSW & QLD with distinct and individual characters; no two are the same.
Browns, greys, pinks, whites, golds, hues, patterns, and bands make our company the largest and most capable supplier in volume, colour range, finishes, products, and applications. Sandstone is an architect’s dream material.
Australia has world-class sandstone reserves (NSW, QLD), and our great land sits upon a giant sandstone basin.

Our quarries predominantly supply ‘Hawkesbury’ sandstone (brown sandstone, the most commonly used and recognised sandstone, particularly in residential projects) and ‘oxidising sandstones’ (golden and cream), which are typical of the sandstone foundations, facades, and ornaments of Sydney’s historic buildings, such as St Mary’s Cathedral, Martin Place, Sydney Town Hall, The QVB, Pyrmont, GPO, and many more.
The fabric of our central city, Sydney, is symbiotic with the Gosford Quarries name and our immortal sandstone products.
100 YEARS OF 100% QUALITY AUSTRALIAN SANDSTONE & SUPPLY
One of the associations with our good name is QUALITY Australian Sandstone.
Gosford Quarries Australian Sandstone is subjected to extensive technical tests by Geotech Laboratories to ensure the integrity and quality of all Australian sandstone products and applications.
When customers order from us, they know that they are receiving the most stringently tested and quality-assured sandstone available in the Australian market.
Amongst councils, commercial civil & heritage partners, we are at the top of mind and the ‘go-to’ for quality & quantity of sandstone supply in Sydney, Melbourne & Brisbane.
100 YEARS OF AUSTRALIAN COMMUNITY INVOLVEMENT
Gosford Quarries prides itself on its position as a responsible corporate citizen. Ingrained in our culture is the need to support and give back to the community, whether local, national or international.

Gosford Quarries has survived world wars, pandemics and some of the most difficult economic challenges. We know the importance of continuing in and embracing the great Australian ANZAC spirit.
Gosford Quarries supports and values local community RSLs and Sub Branches, as demonstrated by our donations of iconic Aussie sandstone to local communities and schools.
100 YEARS OF RESIDENTIAL SANDSTONE SUPPLY
Despite our historic buildings evidencing our historical architectural use of sandstone, the Australian public continues to find revelation and discovery in unique sandstone products and the imagination of architects who love to use sandstone in both historical and contemporary contexts.
Sandstone’s visual beauty is making it an increasingly romantic and popular choice for building materials in Australian homes, both renovations and new builds.
As a building material of great versatility in thermal stability, recyclability, stability, environmental suitability, and visual aesthetic, Australian Sandstone is an exciting product Australian Architects use in juxtaposing and synthesising existing structures to realise unique and beautiful visual and textural designs.
From foundations to cladding, facades and veneer to landscaped rubble and ballast walls, landscaped steps and landscaping logs, interior feature walls and hero fireplaces to higher-end diamond-sawn pavers and tiles forming unique and gorgeous firepits and outdoor fire pits, the possibilities of residential architectural use of sandstone are endless and limited only to one’s imagination.
These designs are memorable, but they also reflect and reverberate the very skin of our land, the sandstone of Australian beaches, and the monolith sandstone boulders – part of the Australian bush landscape within our natural surroundings.
100 YEARS OF COMMERCIAL SANDSTONE SUPPLY
Gosford Quarries Sandstone has been trusted with countless commercial projects, such as Barangaroo Towers and Headland Park, the Australian War Memorial, Hyde Park, Park Hyatt (Sydney), the Westpac Building, the Queen Victoria Building, St Mary’s Cathedral, Wynyard Walk Station, the Parliament of Victoria, and GPO.
