Public Finance and Audit Act 1987

If by reason of the award, order or determination of a court, tribunal or other body empowered to fix salaries, wages or allowances, additional money is required to meet increases in salaries, wages, allowances, pay-roll tax or superannuation contributions payable to, or in respect of, employees whose salaries, wages or allowances are paid wholly or in part out of public money, the Treasurer may appropriate an amount sufficient to cover those increases from the Consolidated Account.
