Substantial Interest

Australia-wide

Plain-English definition

An ownership or beneficial-interest threshold used to determine whether a corporation or trust is a foreign person under federal law.

Why this matters to a foreign buyer

A person generally holds a substantial interest at 20% or more, including interests held with associates; multiple foreign persons can meet an aggregate test at 40%. Indirect interests can also count.
