I think that where you say ($A 000) it should be ($A 000,000) EXAMPLE='Jun 2019 quarter Cashflow($A 000)based on 9Mtpa throughput' ?
So if it is in millions then would it be right to add the EBITDA for the 4 quarters [-15.75+6.80+25.60+38.60]=55.25m then divide then by share issue of 637.28 million to get 0.086 per share EBITDA for the full year 2020?
