We supply premium Australian sandstone direct from our quarries in Kincumber and Winmalee. One call, expert advice, and reliable delivery across NSW and the ACT.
Our Kincumber quarry has been supplying premium sandstone to the Central Coast and beyond for over 70 years. In the Blue Mountains, our Winmalee quarry has been producing white and yellow banded sandstone for over 50 years.
In 2025, both quarries came under new ownership and Rockman Quarries was born: one brand, two great quarries, and a combined century of sandstone heritage.
Today we supply builders, landscapers, architects, stonemasons, councils and homeowners across NSW and the ACT.
No middlemen. Your stone is quarried, cut and loaded by our own crew, so you get a better price and straight answers.
Graded logs, diamond-sawn steps and slabs cut to size on our own saws at Winmalee.
