While studying for a degree in biology at Northern Caribbean University, Nunes became involved with the university radio station as a presenter. He went on to work as a newsreader and reporter for radio networks in the Dutch Caribbean, while at the same time serving as a correspondent for the BBC Caribbean Service.[1] He studied as a postgraduate at the London School of Journalism.[2]
He began working as a freelance announcer on BBC Radio 4 in 2006. Initially he suffered criticism for his strong Caribbean accent,[3][4] but was robustly defended by listeners on the programme Feedback. He is now a well-established announcer, and since November 2017 also reads the news.
Nunes joined the BBC World Service as a producer and presenter of current affairs programmes. He also reads world news bulletins on the World Service in addition to his Radio 4 continuity work. He also features as "Narrator" on Twirlywoos. His style of delivery is parodied by Jon Culshaw on Dead Ringers.
