Abstract: The Northern Grazing Systems project aims to increase adoption of innovative best-practice grazing management by beef producers throughout northern Australia. Four key areas requiring research, development and extension have been identified: stocking rate management; pasture resting; use of fire; and infrastructure development. The three main project components are: synthesis of literature; bio-economic modelling at whole beef enterprise scale; and regional guideline development. Simulations with the GRASP model were used to identify the safe stocking rate for various land types and locations. Safe stocking rate was defined as the fixed stocking rate that produced a mean percentage of perennials in the pasture of 70%. The utilisation rate corresponding to these stocking rates for a fertile land type was 18% at Longreach to 35% at Calliope in simulations using the same parameters other than climate station. For an infertile land type, the differences in safe utilisation rate and the differences in mean pasture production led to a five-fold difference in the safe stocking rate from Longreach to Calliope.
