Thats 28 million shares in two large transactions @ 19.5 (over 5% of ordinary shares on issue and around 4.4% if you include the preference shares).
Originally when the 12 million went through I thought it might have been Ptolemy taking the opportunity to pick up some more, but looking at ASIC's disclosure rules I think they are meant to disclose within 2 business days of a change of more than 1% (however I am pretty sure I have seen other entities take longer than this).
Guess we might find out in the next couple of days. Surely someone will have to lodge a notice.
