Buffett likely wouldn't mess with a small-cap Australian firm.
But that billionaire Australian investor who already owns shares is an entirely different story. He has stated his disgust publicly for short sellers in the past - might be worth his time to kill two birds with one stone by buying a company he believes in and killing short sellers.
On a serious note. This is too risky a situation to be short now. Volume is only ~5M so far with ~53M sold short.
