Certain actions are only significant actions or notifiable actions if the threshold test is met. This Part prescribes values for that test.

There is a single threshold value for action taken in relation to agribusinesses.

For entities (being corporations or unit trusts) and Australian businesses other than agribusinesses, the threshold value depends on who takes the action and whether the action is taken in relation to a sensitive business.

The threshold value for land depends on who takes the action, the kind of land in relation to which the action is taken and other circumstances. Some land has no threshold value.

Most of the threshold values prescribed under this Part are indexed each year.
