Growing up in a country known more for its canals and dykes than its corals hasn’t stopped UQ’s Dr Chris Roelfsema from developing a mission to protect the Great Barrier Reef. It’s more than 15,000 kilometres from the Netherlands to Heron Island, but Chris’s dedication to diving led him from chilly European climes to the coral cay, where he works to map the Great Barrier Reef so it can be better managed.
