A borrowing agreement entered into by a corporate Commonwealth entity, and that includes an overdraft advance and credit obtained by credit card or credit voucher, has no legal effect unless one of three authorities stands behind it: an Act that expressly authorises the entity to borrow, a written authorisation from the Finance Minister (a legislative instrument exempt from disallowance), or an authorisation in the rules. The Commonwealth itself can borrow only where an Act expressly authorises it, and the Finance Minister's borrowing agreements must provide for repayment within 90 days and meet any rule requirements.
