Is it time to nationalize Australia, page-29

I forgot to mention that the company tax code is complex, it's not black and white, a company can announce a 1 bn profit but because it lost a billion the year before the taxable income is near zero, they might even be able to carry/claim losses and maybe investment over more than a year, i don't understand all the tax code very well at all but it goes something like that so one can't just say if a company announces a 10bn profit that it has to pay 3 bn or 30% of it in tax because of previous years financial performances. Like IGO recently wrote off over a billion so that should go against it's profits on a taxation basis.
