Mr President, I ask a supplementary question. Is it not a fact that Treasury specifically denies modelling the medium-term fiscal outlook beyond 2019-2020 and in fact stated in an answer to a question on notice in the last estimates:

Treasury did not model the medium-term fiscal outlook beyond 2019-2020.

Is it not a fact that all Labor claims of net debt being zero by 2022 are based on no more than extrapolation and guesswork?
