Show of Confidence in Qantas?

It looks like the chairman and a bunch of other directors of Qantas went out and bought shares on the market. It's nice to see a vote of confidence in the company from the board. But really 100,000 shares at $1.60 each is not going to be much of an investment for Leigh Clifford given that he was previously CEO of Rio Tinto. Anyway, the stock price is up a little this morning on this news (as I can't see any other reason apart from the positive performance on Wall Street on Friday).
