Busselton is a city on the southwest tip of Western Australia. It’s known for its sheltered beach and seasonal humpback whale populations. The beachfront features the 19th-century Busselton Jetty. This wood pier stretches nearly 2km to the Underwater Observatory, where life in a coral reef is on view. To the city’s northeast, the towering tuart trees of Tuart Forest National Park are home to 2 species of possum.
