Thunderstorm asthma campaign toolkit

Encourage Victorians to be prepared for thunderstorm asthma this grass pollen season.

Thunderstorm asthma events are triggered by a unique combination of weather and high grass pollen levels.

While they are uncommon, they can become life-threatening very quickly for those who experience seasonal hay fever and asthma.

It’s essential that the public is aware of who will most likely be affected, the preventative measures they can put in place and the actions they should take in an emergency.

The below materials are designed to share key information in a clear and concise manner. By displaying and sharing it amongst your community well in advance, you can do your part to ensure everyone stays safe this season.

What you can do to help

You can help by:

  • Sharing the materials in this kit with your community via social media and digital platforms.
  • Directing people to the Thunderstorm asthma page for current information and updates.
