Most of tropical Australia is characterized by marked seasonal and annual differences in rainfall which result in seasonality of parasite burdens and large fluctuations in both the quantity and quality of feed available to the grazing animal. Low rainfall reliability results in low stocking densities which d ic ta te the amount o f environm ental m odification aimed at improving animal productivity which can be profitably achieved. The extensive nature o f the industry makes it unlikely that widespread amelioration of climate or plane of nutrition is feasible within the foreseeable future. It also mitigates again st the control of those disea ses which are of sporadic occurrence and for which vaccines are not available .
