I want to follow up on Senator Cormann's comment with respect to the assumptions underpinning the government's calculation in this regard. Senator Cormann said a moment ago that the revenue loss was expected to be in the vicinity of $1.8 billion forgone. Can the minister explain what are the assumptions underpinning the calculation of $1.8 billion as the cost to Treasury.
