The Parliamentary Budget Officer is required, within thirty days after the end of the caretaker period for a general election, to prepare a post-election report of election commitments. For each designated parliamentary party, the post-election report presents budget impacts of election commitments that would have a material impact on the Commonwealth budget estimates for the current and next three financial years, the total combined impact of those commitments and costing documentation associated with these commitments. A designated parliamentary party is a party with at least five members in the Parliament immediately before the commencement of the caretaker period.
