Enjoy breakfast at your hotel, then meet your guide for today's nature and wildlife tour. Please wear walking shoes, and bring sunscreen, a hat, a water bottle that can be refilled during the day, plus a light rain jacket in case of inclement weather. *Although this tour is vehicle-based, most of the day is spent outside the vehicle on a number of easy, flat terrain bushwalks so that you can get close to nature. Passengers must be able to walk unassisted at least one mile on uneven dirt surfaces to ensure wildlife sightings. There may be up to five walks of this duration during the day. Travel just 45 minutes west of Melbourne, to the bushland of You Yangs Park. This area is of great significance to the local Aboriginal People of the Wathaurong Tribe; the granite rock formations of the You Yangs have served as a meeting place for Aboriginal People from all over southeastern Australia. The park is also home to a population of wild koalas that are researched and monitored to ensure the best possible sightings. Walk through the gum trees searching for koalas, wallabies, kangaroos, and birds in their natural setting. Your wildlife guide will introduce you to each koala as an individual, with a history, social life, and family. You will also learn about threats to koala habitats, how to approach koalas quietly, and how to watch them from a respectful distance without disturbing them. At one of five boneseed-removal sites, stop for a few minutes to improve the koala habitat by removing some of these noxious weeds. For lunch, enjoy a picnic served under the gum trees, including gourmet sandwiches, fruit and cakes, and Australian billy tea, the traditional tea of the swagmen. Leave the You Yangs and travel just 10 minutes to nearby Serendip Sanctuary. Drive, then walk through gum trees and across grasslands, seeking mobs of eastern grey kangaroos. They are wild and secretive, and with the help of your guide, you'll walk quietly along kangaroo tracks and use trees and bushes for shelter during your search. If you spot them before they see you, you'll be able to observe natural kangaroo social behavior. Or, they might see you first, and you'll witness the magnificent sight of a wild mob hopping-fast, powerful, and silent. Also look out for emus, and take a short walk to the billabong for a glimpse of the waterbirds that live there.
