rules need to be changed ASAP

Australia needs to change its rules as to when companies announce announcements so to protect investors from investing in the wrong companies.
The most common example is an announcement when a company says it has done a placement of so much $$$$$ to sophisticated investors and not disclosing WHO THOSE SOPHISTICATED INVESTORS ARE, if you do not have anything to hide, you should disclose who the party is that purchased those shares, a company could make up that made a placement to sophisticated investors and the real thing that could be doing is just issue more shares and spend that money on itself [directors] without any existent sophisticated investors.
I have seen this announced several times and as a shareholder you are still in limbo as to what the company is doing.
I welcome any [good or bad] replies and hope that most of you have dialed that number that I posted earlier on today.
