Queensland Consolidated Acts(1) All land below high-water mark, including the beds and banks of tidal navigable rivers--
(a) is the property of the State, unless the land is inundated land or a registered interest in the land is held by someone else; and
(b) may be dealt with as unallocated State land.
(2) To remove any doubt, it is declared that if a tidal navigable river forms the boundary of a parcel of land or a person owns land on both sides of a tidal navigable river--
(a) the land below high-water mark is and always has been the property of the State; and
(b) if the line of the high-water mark shifts over time by gradual and imperceptible degrees--the boundaries of the parcel shift with the high-water mark.
(3) No act to occupy, use, build works or remove material or product, with or without lawful authority, divests the State of its ownership of land below high-water mark.
