Quarry material on land under State tidal water is generally owned by the Queensland Government. To remove this material, you must apply for an allocation of quarry material (an allocation notice) and pay a royalty for the material removed.
This applies to:
extractive industry (e.g. for sand and gravel for construction purposes)
capital dredging associated with some form of tidal works (e.g. excavation of a marina basin, dredging of a new navigation channel)
Removal can involve taking the material for sale, using the spoil for reclamation or fill above the high water mark, or removing the material for dewatering or another environmental purpose on land.
The purpose of regulating the removal of quarry material on Queensland's coast is to avoid potentially negative impacts on coastal resources such as degradation of water quality, changes to hydrodynamics of tidal waterways or loss of sediment that feeds coastal processes such as beach building.
