Port Phillip Heads is the entrance to Port Phillip Bay, located in Victoria, Australia. It consists of two main channels, the North Channel and the South Channel, which allow ships to navigate into the bay. The heads are characterized by dramatic cliffs and rocky outcrops, providing a natural barrier between the open ocean and the sheltered waters of the bay. The area is also home to several important landmarks, including the Point Nepean National Park and the Cape Schanck Lighthouse. These sites offer stunning views and are popular for recreational activities such as hiking and birdwatching, making Port Phillip Heads a significant natural and historical location.
