A normal afternoon swim off the coast of Cape Kidnappers dramatically changed for Doug Cushing.
He had been swimming offshore with his two sons, father and uncle.
The group was heading back in on the boat, when a massive slip of rock and dirt came crashing down the cliff face.
"Initially it was just shock," he said when asked about seeing the cliff come down.
He said they sped up to get to a tour group who had been out visiting the gannets.
