The purpose of the 2017-18 Portfolio Supplementary Additional Estimates Statements (PSAES) is to inform Senators, Members of Parliament and the public of the proposed allocation of additional resources to government outcomes by entities within the portfolio.
The PSAES facilitate understanding of the proposed appropriations in Appropriation Bill (No. 5) 2017-18 and Appropriation Bill (No. 6) 2017-18. In this sense the PSAES is declared by the Appropriation Acts to be a 'relevant document' to the interpretation of the Acts according to section 15AB of the Acts Interpretation Act 1901.
