A former Wisbech Grammar School pupil has produced a prime-time BBC2 documentary series about one of the most beautiful marine waters on the planet.

Will Millard, 31, of Upwell, investigates the Coral Triangle in the Western Pacific in a three-part series which has been branded the documentary of the week in the latest edition of the Radio Times.

In the first of the programmes, he meets the Bajau spear fishermen of Indonesia, who are famous for their fishing and swimming skills.

It was during a classics tour of Italy that he decided to be an explorer. He fell in love with West Papua, Indonesia, where he spent the next decade leading jungle expeditions.

Mr Millard, who returned to the school as the guest of honour at a speech day ceremony in 2013, said: “The response has been phenomenal since the broadcast, the first of three, on the Bajau spear fishermen of Indonesia.

“I have had upwards of two thousand messages from people interested in the issues raised in the programme and we’ve been featured in most of the national newspapers.

“It was deeply humbling to spend my time with such unique communities, who show such incredible resilience as their environment changes all around them.”
