Observed every year on May 3rd, Wild Koala Day was established by concerned koala conservationists across Australia to celebrate this species and to protect their habitats. Anyone is welcome to join, and is encouraged to pin a gum leaf (or any other leaf if you don't have access to eucalyptus) to their shirt, change their profile photo to a koala, and/or share a koala photo on social media, tagged #wildkoaladay.
