Although once a year it will appear in the back of the annual report, if the percentage is still in the top 20 shareholders. But not "live" data as such.

True @rh8178 except that data is current only as at June 30th for the FY that the AR covers, so far from "live" as the AR is usually produced 2 to 3 months later. I use those lists for keeping track of management interests, but even that is challenging because they usually use holding companies and family trusts - or super funds with weird names that often don't have any obvious link to the names of the people who control them - so I have to keep my own set of records regarding who owns what - and then try to track whether their exposure is being maintained or increased over time. In the case of founders, I do give them some latitude to reduce their exposure over time, as that seems entirely reasonable to me, especially founders who have almost all of their net worth tied up in the one company, but for shorter term managers, I do like to see them increasing their exposure or at least maintaining it, particularly for the first 5 to 10 years that they are working for a company. That sort of alignment is a good indicator that they are more likely to make decisions or approach decision making from an "owners" perspective rather than just as a manager.
