The owl can be found along the East Coast of Australia where they are associated with the forests of the Great Dividing Range. They are listed as vulnerable in Victoria and New South Wales.
They usually breed in the winter months and require a large hollow (up to 2 m in depth) and in trees which have a diameter of 80 cm or more. Dr Rob Clemens from Birdlife reckons it can take 100 to 300 years for a tree to reach the appropriate size with hollows!
If you have the fortune to see or hear one you could report it to the Urban Birdlife Program - Powerful Owl Project. You can contact them via their website at Powerful Owl Project | BirdLife.
Its a sight you won't forget and its just another reason why we need to conserve our remaining forest areas.
