Helium2Go Claimed 

Helium 2 Go is a Brisbane business, run and owned by Brisbane locals, we are not a corporate entity, however, we have an intimate connection with the industry with over 30 years experience in the balloon and party industry.
The primary reason we set up Helium 2 Go was to stop people buying and using disposable helium cylinders as they are incredibly bad for the environment.
Our Helium Cylinders are refillable, not disposable, they are industrial strength lightweight brand new aluminium cylinders that we fill, you use and then we refill over and over again. No landfill, environmentally friendly refillable helium cylinders.
We fill our cylinders ourselves and when we say they will inflate 50 or 100 balloons, we mean true 28cm helium grade quality balloons, not cheap 23cm balloons that you will find in most disposable helium kits.
