The study examines the energy consumption, energy input-output relationship and benefit/cost ratio of wheat, rice and barley crop production system in Coleambally Irrigation Areas (CIA) and Murrumbidgee Irrigation Area (MIA) of New South, Wales, Australia. The values of all energy inputs and output were converted to energy farm. Economic analysis was performed for each crop. Results revealed that chemical fertilizer consumed 47, 43 and 29 % of the total energy inputs on wheat, rice and barley growing farms, respectively. Wheat consumed 3028, rice 6699 and barley consumed 2175 kWh per ha. Similarly, wheat utilized 2852, rice 17754 and barley 856 m3 per ha. Average energy output of wheat was 27874, rice 44885, and barley obtained 17865 kWh per ha. Wheat was most energy efficient crop compared to rice and barley, whereas barley achieved the highest water productivity. Cost of production on wheat crop was 323, rice 896 and barley was A$ 246 per ha.
