Helium balloons are a staple at Sydney parties - and for good reason.

They add instant colour, height and energy to any setup, whether you’re decorating a backyard, venue or restaurant table. But if you’ve never ordered them before, it’s worth knowing how they work, how long they last, and what to expect with delivery.

In this guide, we’ll break down the key things to know before you hit “add to cart”, and show you why Party Splendour’s helium balloon range is one of the most trusted in Sydney

How Do Helium Balloons Work?

Helium is a lighter-than-air gas that makes balloons float. Unlike regular air, helium creates lift, allowing latex and foil balloons to rise and hover. It’s safe, non-toxic and commonly used in events of all sizes. The float time depends on the balloon type and size — which we’ll cover below.

How Long Do Helium Balloons Last?

One of the most common questions we hear is: how long will my balloons float? Here’s a quick guide:
  • Standard Latex Balloons: 8 to 12 hours
  • Helium Latex with Hi-Float Treatment: Up to 24 hours or more
  • Foil Balloons: 2 to 5 days
  • Jumbo Balloons: Often float for several days (with Hi-Float)
For best results, keep balloons indoors away from heat, wind or direct sunlight — Sydney’s weather can shorten float time if not stored correctly.
