The Big 4 Adventure Whitsunday Reef Festival celebrates the amazing natural wonders of the Great Barrier Reef.

The packed programme caters for all ages and includes street parades, fireworks, a family fun day, markets, helicopter rides, a bareboat open day, and a sand sculpting competition.

When the sun goes down there are fashion shows, a comedy gala, and cocktail parties.

Each night "Beats on the Beach" on the Esplanade will feature top musicians, or you can catch an outdoor movie beside the lagoon.

There's also an educational component that promotes reef preservation. Many events are free.
