Very sad news. Seems he was visiting his other daughter, Antonia, in Singapore and somehow tragically fell to his death. I hadn't realized he was on staff at the University of Technology-Sydney for many years, including when Hugh attended.
Sad indeed, and rather odd, but nice that they had time to spend together just recently.
