"So I rushed to the top and said, 'There's a shark, there's a shark'. But it momentarily disappeared."
Mr Bade had tried waving to the friend in the boat for help. "At that moment the shark came back on Rob's side and sort of glided up to Rob. So he gave it a poke in the nose with his gun and it went away."
Both men had floated in the water back to back, spearguns at the ready when the shark returned. "It came back. It was probably 1.5m from us, trying to look at us. It was like that for about five or 10 seconds but it felt like a long time." After a few prods with the spearguns the shark left and the men got into the boat.
Back on dry land a few days later, Mr Bade thinks the shark was probably more curious about the speargun rather than hungry for lunch. He hadn't realised he was bitten until afterward.
"I think it must have been a bit inquisitive ... and my finger got in the way," Mr Bade said.
"It was the smallest bite from the biggest shark."
The Shark Research Institute says the bronze whaler shark is known for biting people, particularly spearfishers, and is a fast-moving shark that can leap out of the water. Bronze whalers were often found in warm temperate to subtropical waters and around offshore islands in deep water.
