Every September, thousands of people from over a hundred tribes come together in Goroka, Papua New Guinea, to celebrate their unique culture. In this traditional festival, called a sing-sing – the biggest of its kind in the world – there's a mêlée of dancing, singing and a rainbow of colourful outfits on show.
Photographer Fabien Astre visited the festival last year and took these stunning pictures.
Speaking about his trip, he said: "Seeing all the different cultures from just one country is amazing. The people are friendly and happy to see foreigners being interested in their culture."
