The Commonwealth has a number of discretionary mechanisms to address financial impacts of decisions of the Commonwealth that have an unintended, unfair, unreasonable or inappropriate impact.
The CDDA scheme allows Commonwealth agencies to consider and provide compensation for inappropriate actions (defective administration) by that agency that has caused you a loss (detriment).
Act of grace payments and waivers of debt are ‘last resort’ mechanisms, which will generally only be considered once alternate remedies have been sought.
