ABOUT US

About Us

Austone Pty Ltd was established in 1971 with the objective of locating pebble deposits where the pebbles exhibited particular characteristics such as hardness, shape, competency and colour. Successful exploration, extraction rights and plants construction enabled production to start in 1974 - and have continued uninterrupted ever since.


Services We Offer

The Nambucca pebbles steadily change in overall makeup from the smallest to the largest grading. The sands and fine pebbles (1.6mm and 3mm) are composed almost entirely of quartz. As the size of the pebbles increase the quantity of other rock types also increases, particularly the percentage of greywacke (dark grey, highly indurated fine sandstone and siltstone.)


As a result the appearance of the material changes from a dominant single colour of yellow in the finer sizes through an increasingly speckled appearance in the middle ranges to predominantly grey above 50mm.
