There appears to be a small amount of wet stress in northern Australia under current climatic conditions
(Figure 3.18, a). There is little impact of climate change on the distribution of this stress. The
combination of slight increases in wet stress, and a coincident reduction in the moisture index are
enough to reduce the climatic suitability of small patches of northern Australia under each of the
scenarios that include a 10% precipitation increase (Figure 3.18,e-g), and the highest water use
efficiency scenario with a reduction in precipitation (Figure 3.18, d).
