Intensive rotational grazing has been widely adopted by farmers across southern Australia, to improve financial, environmental and personal elements of farming businesses. Often the shift to an intensive rotational grazing system has been associated with changes to livestock enterprises, stocking rate and phosphorus fertiliser application, making it difficult to determine the specific role of grazing management. An experiment was run on native pasture at Panuara (33'27'S, 154'56'E) over a three year period (2008-2010) to investigate how increasing the intensity of grazing management from continuous grazing (one paddock, 1P) to flexible 4- and 20-paddock rotational systems (4P and 20P) influenced profitability and environmental outcomes. Lamb weaning weight decreased with increasing grazing intensity (average weaning weight 1P = 33.7, 4P = 30.6, 20P = 29.9), but higher stocking rates were possible with 20P (average stocking rate 1P = 6.4, 4P = 7.1, 20P = 7.9 DSE/ha), due to higher feed on offer. Grazing system had limited influence on pasture composition, although groundcover and herbage mass were periodically higher in 20P, particularly in drier autumns (2009 and 2010). Gross margin was higher in the 20P system in 2010 when stocking rates were higher and lambs retained after weaning, with little difference at other times. Using the experimental results from 2009 and 2010 there were strongly positive internal rates of return (IRR) in moving from 1P to 4P and 20P systems when infrastructure was in place (18.3% and 23.9% respectively), however, IRR decreased as the investment in infrastructure increased.
