OK, I just looked it up. Here is the relevant clause:
"Persons who, together with their associates, have relevant interests in voting shares representing 5% or more of the votes in a listed company, body or listed registered managed investment scheme, must disclose details of their relevant interest. Disclosure must also be made when a person’s substantial holding changes by 1%, they cease to have a substantial holding or they make a takeover bid."
Thanks guys!
