Three decades ago, former Queensland MP Rob Pyne dived off a sailing boat unaware there was a sandbank lying just below the surface of the pristine blue water. Then 23-year-old suffered a broken spine - an injury that would confine him to a wheelchair and mean he could never walk again. It's a day most people would like to forget but this week he was handed a bittersweet reminder of that sunny afternoon. A waterproof wallet he had tucked between his speedos and footy shorts when he jumped off the boat was found buried in the mudbanks of Cairns beach, holding his 1991 driver's licence and bank cards.
