Rogue wave believed to have swept person off rocks at Terrigal A ROGUE wave is believed to have swept a person off a headland north of Sydney this morning. A witness reported seeing a person walking on rocks near the Terrigal headland go in the water just before midday today. The Westpac Life Saver helicopter began an aerial search and also winched a recue crewman onto the rocks where the man was last seen. "Although conditions are calm there are some rogue waves out there," said Westpac Life-Saver spokesman. We have dropped a dye into the water as well so we can see what directions and where the currents are going which may help us locate the missing person. A life saver jet ski is also assisting the search.
