The use of water and its cost remain a key part of the production-profitability equation for many cane growers. Over half of the Australian sugarcane crop relies on either full or supplementary irrigation. Water availability varies by district, with the Burdekin region having the most reliable supply with a full irrigation allocation each year. Water allocations in the other irrigated districts, such as the Atherton Tableland and the Central and Southern Regions, are more variable.
Furrow, overhead low-pressure systems, including centre pivot or lateral move, and overhead high-pressure systems, including water winches and travelling booms, are the most common irrigation systems in use. However, emerging technologies such as drip irrigation are being seen as a new way to irrigate as they conserve water and lower energy inputs.
