Greg and Helen Wragg have been coming to Fiji's Northern Yasawa Islands for more than 20 years.
It's not the perfect sunbathing beaches or the spectacular snorkelling that's luring them back, for the Wraggs - it's the Fijian people and their unique culture.
"A lot of tourists come to Fiji and they stay in the Sheraton or the Hilton and they never ever get to see the real Fiji, particularly the Fijian culture that exists in the Yasawas," says Greg.
For the past five years Greg and Helen have been bringing school groups of around 30 teenagers to live in a village - either Nabukeru, which is visited by Captain Cook Cruises, or Matacawalevu - for just under a week.
"They're changed people at the end of those five days," he said.
