What makes a Happy Balloons setup different

Our work combines balloon design, handmade details and practical on-site installation. The result is a coordinated setup shaped around the event, venue and brief, with every detail planned to work together.

Custom design

We shape the balloon plan around the theme, colour palette, venue and brief. The Eight combined draping, Chinese floral styling, handmade flowers and table details into one coordinated scene.

Explore The Eight first-birthday setup

Handmade balloon work

Handmade balloon flowers, figurines and themed details can turn a standard display into something personal. The Chatswood birthday project adapted balloon figurines into candy-cup party favours, while The Eight included handcrafted balloon flowers.

On-site setup and execution

We plan transport, access, fixing and installation around the real site. The Edmondson Park arch used an aluminium truss system across a wide outdoor opening, while the Mosman garland used suction cups on glass doors.

Customer Reviews for Happy Balloons Sydney

We’ve worked with Happy Balloon for many events, and they consistently do an amazing job. They handle even the most complicated balloon challenges and are always professional, dedicated, and easy to communicate with. I can’t recommend them more!

Coral Li

Happy Balloons Chatswood did an amazing job for my 21st. The installation was flawless and looked so elegant. I also really appreciated their 'end-to-end' service—having them come back to clean everything up was a lifesaver. Fantastic service and high-quality work! i would recommend to anyone!!

selena maree

Very good experience, balloons were wonderful and bigger than I expected, fit the prompt perfectly. Delivery was efficient, they were happy to deliver earlier in the day on short notice. The balloons lasted a long time. Would definitely buy again in future!

Stephen Borg

I hosted an big event for around 150 people on October 26th, and I’m so grateful to Mei from Happy Balloons Sydney! She was professional, attentive, and truly understood the style I envisioned. The balloon decor exceeded expectations and was a big hit with the kids, who loved the live balloon creations on-site. I’d give them a perfect score—100+ if I could! Absolutely five-star, professional service, and I’d recommend them to all my friends!"
