5% is still a lot- about 300k shares. In any case the company seems to only report changes in ASX CDIs, not NASDAQ common stock: see the last announcement. It's a bit unclear what needs to be reported to the ASX now. I'd normally expect to see a change in directors holding too for those shares acquired by Paul Purcell, but maybe this was also waived for some reason.
This is from the last sub-holder notice: no mention of common stock
