When Balloons Fly, Seabirds Die

Balloons are the #1 deadliest form of litter when ingested by seabirds*.

We love balloons, but when they’re used outdoors they can escape into the environment and end up in oceans or waterways, harming and even killing precious wildlife.

*CSIRO 2019

The CSIRO 2019 found that seabirds are up to 32 times more likely to die when they swallow balloons than any form of hard plastic. 

Balloons can look like food floating on the water’s surface and animals can ingest them or even feed them to their young. This has led scientists to name balloons as one of the disproportionately deadliest litter items to marine wildlife such as seabirds and turtles (CSIRO 2020). It doesn’t have to be this way! 

230,000 people and hundreds of schools and organisations have promised to blow bubbles, not balloons at outdoor events.

You can too!

Releasing balloons is littering 

Releasing balloons into the environment, whether it’s a single balloon or a whole group of balloons, is littering and therefore illegal in Victoria. You can find out about the penalties associated with releasing balloons on the Environmental Protection Agency’s website www.epa.vic.gov.au/balloons 

This includes latex balloons which can be inaccurately and misleadingly labelled as ‘biodegradable’ (Gilmour & Lavers 2021).

Measuring the impact of this campaign

Our partners at Phillip Island Nature Parks have measured a steady reduction in the number of balloons and balloon clips and strings being found on Phillip Island beaches. 
Compared to 2017/2018, the total number of these items observed on the island’s beaches was 57% less in 2018/2019. This is great news!

Meet the seabirds most affected by balloons

Flesh-footed Shearwaters - near threatened

These migratory birds breed in colonies, with one of their main colonies found on Lord Howe Island. Here their numbers are in decline due to mistakenly ingesting rubbish and even feeding it to their chicks.

Short-tailed Shearwaters - population decreasing

Short-tailed Shearwaters are one of the few migratory birds that come to Australia to breed on Phillip Island. Both parents feed their chicks when they return from foraging at sea, and the shearwaters remain on the island until April, when the fledglings are strong enough to start the 15,000 km flight back to Alaska. On the long journey, many birds mistake plastics floating on the ocean’s surface as food.
