In 2011 and 2012, he led a team of Aussie divers to record depths of 194 and 221 metres in what’s believed to be one of the world’s deepest cold water caves, searching for the source of the Pearse River in New Zealand. It required the team to set up a series of survival pods at intervals to allow divers to decompress, rest and eat in the near-freezing waters along the length of an underwater river – an experience that could prove invaluable in the current rescue mission.
He filmed the dangerous and complex mission for National Geographic.
