Tonga has been listed among the world's best sites for responsible whale watching by the Whale Heritage Sites initiative.
Allan Bowe, Tonga's first licensed whale watching operator and who pioneered the industry in Tonga in 1993, says he's delighted at the announcement.
Mr Bowe says most whale-watching operators provide employment in the villages by hiring Tongan skippers and crews.
He says the industry not only helps support whale conservation in Tonga but it has also become a big contributor to the local economy.
