A couple has been escorted from the Royal National Park near Otford by rescue crews after they became lost while bush walking. A 27-year-old man and his 21-year-old female partner were walking through the Royal National Park about 5:30pm yesterday to visit the Figure 8 rock pools when they became lost. Police were contacted shortly before their phone went flat and a rescue operation initiated. “Luckily, they had a phone with them and reported it to us around 8:20pm before it went flat,” says Wollongong Duty Officer Darren Kelley. “They saw the flashing lights of the rescue team at around 11:30pm and both persons were located unharmed.”The man and woman are from South America but living in Australia on student visas.Officer Kelly says the incident is a reminder for people to use common sense when starting bush walking late in the evening and to fully prepare for their trip.
