Founders: Alfred and Kathleen Neumann.
Family Members: Robert, Margaret, John, Peter and Bruce.

Alfred Neumann moved to the Gold Coast from Laidley in South East Queensland in 1922.  As a cabinet maker and builder, he eked out meagre living building homes for locals before his entrepreneurial aptitude became apparent.  In 1948 Alfred and his eldest son Robert established their first company, Pacific Minerals, a sand mining and mineral processing company that produced rutile and zircon.  This Company continues to operate today under the name of Currumbin Minerals.

Neumann Contractors - The Beginnings...

In the early fifties, Robert, Margaret, John, Peter and Bruce continued to follow in their parent’s footsteps by building primitive dredging equipment which supplied sand to the concrete industry and, in particular, the Little Nerang Dam Project.  This initiative founded Currumbin Sand and Gravel and Neumann Dredging Company (now known as Neumann Contractors).

Neumann Contractors has the following business units:

Growing Demands - Growing Businesses

Complementing the original companies, Nucon Concrete and Nucrush Quarries commenced operations to service the growing demands from the construction industry.  In conjunction with the ever-increasing demand for concrete, the family zealously researched construction products and market opportunities, which led them to explore the reinforced steel industry in Europe.

Returning to Australia, the family built their own reinforced steel plant in its current location at Currumbin.  To this day, construction projects all around Australia utilise Neumann Steel products such as Ribmesh and Ribwire.

Market Opportunities

River Sands and Neumann Developments continued to identify market opportunities and commenced operations.  River Sands manufactures filter sands, coloured oxides, and pre-bagged concrete and distribute these products worldwide. Neumann Developments provides quality land sub-divisions throughout Queensland.

The Neumann companies have helped shape the Gold Coast.  Over many years they have constructed hundreds of kilometres of canal developments, established quarries and provided concrete and rock products to varied industry groups.  This foresight and vertical integration ensure the successful expansion and ongoing success of the Neumann Group of Companies.
