Key Points

• The Australian Greens' (the Greens) 345 commitments would result in a decrease in the fiscal, underlying cash and headline cash balances over both the 2025 Budget forward estimates and medium-term periods (2025‑26 to 2035‑36), relative to the Pre-election Economic and Fiscal Outlook (PEFO) baseline.
• The Greens' platform would result in a decrease in the underlying cash balance of $5.2 billion over the forward estimates and $343.1 billion over the medium term, relative to PEFO.
• This would result in an underlying cash deficit of $49.6 billion at the end of the forward estimates and total underlying cash deficits of $156.8 billion and $670.1 billion over the forward estimates and medium term respectively.
• The impact reflects an increase in receipts from major tax changes and a reprioritisation of funding from defence, that only partially offsets increases in payments for social protection, education, health and general public services.
• The Greens' platform would result in higher government gross debt across the period, an increase of $703.0 billion by the end of the medium-term period relative to PEFO, reaching $2.2 trillion (46.9% of gross domestic product (GDP)). Public debt interest payments would be around $136.4 billion higher over the medium term.
• The Greens did not publish a consolidated list of the financial implications of their platform prior to the election.
