Senator WONG (South Australia—Leader of the Opposition in the Senate) (14:08): Yesterday, the Prime Minister refused to say whether the total cost of his corporate tax cuts over the 10 years from 1 July 2018 is more or less than $100 billion. So I ask this minister: is the total cost of the government's corporate tax cuts over the 10 years from July 2018, both legislated and proposed to be legislated, more or less than $100 billion?
