"... we released a policy that's costed at delivering $1.9 billion in revenue over the forward estimates. And that was about a series of measures in respect of multinational tax evasion. The primary one, I think you mentioned before, was actually about thin capitalisation - which is, in other words, about how much debt a company can load up to their Australian businesses versus how much debt they have globally. And as you probably know, you can get some tax breaks on up to 60% of your Australian debt, so if you look at the world-wide gearing ratio, then that's going to be a much more accurate way of working out how much tax people should be paying here in Australia."
