Ann: Becoming a substantial holder, page-10

"Naked shorts are illegal in Aust"

Apparently so is in South Korea but that didn't stop major international funds doing it. But over there at least the regulators caught them.
In Aust I doubt they are even looking for naked shorting.
And then there is the matter of Form 603 meant to be issued to ASX in a timely manner whenever there is a change in substantial holdings, apparently as long as that's done during the current financial year or close enough to that then our regulators are satisfied with it and patting themselves on the back for a job well done.
