If you live in an area impacted by natural disaster or you drive frequently near bushland or in regional / rural areas you can be part of wildlife rescue by carrying your own rescue kit. If the diagram makes you feel a bit overwhelmed, please ask what some of the items are for. For example, the line marking paint is to mark a dead female marsupial to show that her pouch has been checked for a joey.
Very young joeys with no fur, called pinkies, attached to teats should NOT be pulled off as it can do their mouths great damage. Most everyday people don’t feel confident with rescuing pinkies so it’s best if you call a trained, registered wildlife carer. Sometimes that’s not possible and I’m happy to provide more details if you are interested. For older joeys and all other animals it’s best to keep them warm, in a darkened container lined with towels, blankets, etc, and get them to a vet or a wildlife carer asap.
