Econometric models of export demand for Australian dairy food (milk dry and butter) are developed and estimated in this paper using unrestricted error correction modelling procedure and data for the period 19752000. The findings indicate that, in the short run As well as in the long run, export demand for Australian milk dry and butter in Thailand decreases when Australia's export price relative to that of competing countries increases. The estimated long run relative price elasticity of export demand for Australian milk dry and butter in Thailand are, -2.75 and -1.13, respectively. Export demand for Australian butter in Thailand declines when the Thai baht depreciates against the Australian dollar, and the estimated long run exchange rate elasticity of demand is -6.34
