so I wonder what's the limiting factor that constrains plant capacity to 1.3mtpa of urea - is it the capital required for an expansion to say 2 or 2.5mtpa or the volume of gas feedstock that's available, or was it their estimation of the market size? What if we establish the plant at 1.3mtpa to begin with, and then as we find more gas in the Perth basin we expand it over the next 5 to 10 years or so to meet market demand. As the Haber plant starts to generate substantial cash flows that could be reinvested in adding another processing train to fully satisfy at least the Australian demand.
