This appendix provides historical data and forward estimates for budget sector underlying outlays, revenue and underlying balances; and for Commonwealth general government net debt.
Table D1 provides details of the budget aggregates for the period 1960-61 to 2001-02. The underlying budget balance is revenue minus headline outlays excluding net advances to other sectors. Net advances comprise net loans from the budget (new policy loans and advances less repayments) and net equity injections (injections/purchases of equity less equity sales). Classification differences and revisions, as well as changes to the structure of the budget, can impact on comparisons over such an extended period. In particular, there are some classification differences in the data relating to the period prior to 1976-77. This means that data for the earlier period may not be entirely consistent with that for 1976-77 and later years.
Table D2 provides details of tax, non-tax and total revenue for the period 1960-61 to 2001-02. These revenue data are compiled on a consistent basis from 1976-77.
Other factors which affect the comparability of budget aggregates between years are:
While approximate adjustments can be made to identify trends in budget aggregates on a generally consistent basis, the further back this analysis is taken, the less manageable that task becomes.
A detailed discussion of the comparability of budget aggregates since 1960-61 is provided in Statement 5 of 1992-93 Budget Paper No. 1.
Further details of the coverage of the budget sector and the changes in the classification of budget transactions are provided in Appendix E of this Statement.
Table D3 provides Commonwealth general government net debt data for the period 1974-75 to 2001-02.

(a) Data for 1987-88 to 1996-97 are from ABS Public Sector Financial Assets and Liabilities (Cat. No.5513.0). These data take into account the reclassification of universities from the general government sector to a separate multi-jurisdictional sector. Data for years prior to 1987-88 are Treasury estimates which do not exclude universities. The adjustment for universities has only a negligible effect on the estimates.
