IT'S not too late to enter the Rotary Street Parade - one of the highlights of the Whitsunday Reef Festival, on Saturday, August 6.

With some serious cash prizes on offer - not to mention the community pride involved - it's a great excuse to dress up, have some fun with friends and colleagues and promote your business, school or community group at the same time.

It is also a fantastic spectacle, and hundreds of people are expected to line the Airlie Main Street from 4pm to cheer and wave the many floats as they go by.

This year's street parade theme is Finding the Reef and entries can be a walking entry or a float or a combination of the two, with prizes for Best Business, Best Not-for-Profit, Best Finding the Reef theme and Most Unusual & Wacky.

"The world really is your oyster when it comes to dressing up your float," organiser Merewyn Wright, from the Rotary Club of Airlie Beach, said.

"Entrants are encouraged to get as creative as they like - we're looking for lots of fun and smiling faces to bring our main street to life, so think colourful coral, tropical fish, marine life and the Great Barrier Reef."

The closing date for entries is Monday, August 1, 2016, and entrants are notified before the parade of their position and start time.

There is a charge of $20 per business (except festival sponsors, not-for-profit groups and schools, which are free).
