Make sure you don’t miss Australia’s largest and most exciting kite-flying festival this year, which promises to be a great day out for the whole family. The skies will come alive with hundreds of kites of all shapes and sizes from local and international kite makers and fliers.

It’s not just the experts who can fly their kites — come down and fly your own. If you don’t have a kite, you can buy one from one of the stalls in the park, or better still, make one at one of our kite-making workshops.

Then there’s the multicultural entertainment program in the Pavilion Courtyard Amphitheatre of great music, dance and performance. The headline act this year is Rastawookie. Their music is a fusion (结合) of many different styles from South America, the Caribbean and western countries. There will also be free music and dance workshops, so why not try your hand at one of these? For the children there will be additional rides, face painting, jugglers (变戏法者), stilt walkers, and clowns. After all these activities, you probably can’t wait to eat. Choose from one of our fabulous multicultural food stalls offering food and drinks from all over the world or for something simpler — nothing could be better than a good old-fashioned sausage!

There’s so much to do and so much to see, so if you’re up for a great day, then the only place to be on Sunday, September 9th is down at Bondi Beach for Sydney’s most exciting, fun and family-friendly festival.
