He purchased 1,000,000 shares at 5c last year through his super when it was trading around 5.5c. That's not including the other times he bought when it was trading well above 10c. I can't remember the exact amount but remember the announcement when it was trading around 15c. Look up UUVs previous announcements and his holdings and you'll work it out.
So why did he make the investment? I don't think he would've made the investment to save the company. Maybe he's privacy to more information and not speculation like the rest of us.
