 Pollen grains are microscopic particles that can be blown around in the atmosphere and their role is really for reproduction of plant species. The wind-borne pollen that contributes most to hay fever in the ACT tends to be the grasses and particularly rye grass. Pamper is a real hotspot for pollen-related allergies. We think this year is going to be particularly severe. We've seen counts as high as 2 to 300 grains in a cubic metre and that's a very significant number. We have a pollen monitoring counter that measures the pollen in the atmosphere. That information will be made available on the app, on our Facebook and Twitter page as well. And I encourage everybody to download that because it will be used for surveys. It will be able to give you daily updates on the pollen in the atmosphere as well as enable you to actually input your health data in terms of how you're feeling that day with respect to hay fever.
