More than a 100 people, including students from Prince of Songkla University’s Phuket campus, volunteer divers, local vendors and operators, and company workers participated in the morning initiative.

The move involved collecting trash both on the beach and underwater. Among the items collected were fishing nets, glass bottles and rubber tyres.

“We are doing business on Hei island, so this effort is our way of saying ‘thank you’. Cleaning up the island will not only help preserve marine life, but also play a big part in improving tourism,” said Suriya Thamchu, chairman of Nonthasak Marine Co Ltd, which organised the clean-up.

“We received positive feedback so we plan to do this again in the near future,” he said.
