A water works licence stating its purpose as 'Irrigation Stockwatering' authorises the taking and use of water for those purposes, not merely the conservation of water. Where a licence renewal is void for breach of natural justice, the original licence continues in force under s 4.21 of the Water Resources Act 1989 (Qld), and subsequent purported renewals or reinstatements based on the void renewal do not affect the original licence's operation. The principle of non-derogation from grant may apply to statutory licences, such that a licence to take water impliedly authorises the use of reasonable means (such as a pump) to extract the water.
