I still have tried to figure out approximate profit per year, but been struggling, because I'm not so fully aware of Australian corporate taxation. I would gladly open new discussion. Could somebody confident enough can write out approximate figures from EBITDA to profit. Just pick reasonable interest rate for capital and show calculations. I'd be happy if somebody would start and then the rest, who feel confident, can comment these calculation or add more details. Let's see what we can come up to and in the end, somebody could do conclusion.
