Worth a closer look
Grew past the open-tender threshold: first published at $125k. The Commonwealth Procurement Rules require an agency to estimate a procurement’s maximum value, including options and extensions, before choosing how to buy. Open tender is generally required at or above the threshold.
Common explanations: Extra work that could not have been foreseen at award. A nominal value published at award and updated once the actual amount was known. A construction contract outside AusTender category 72, which we cannot tell apart from other services.
