English: Some birdlife of the Casuarina Reserve. Casuarina Coastal Reserve has kilometres of unspoilt beaches with endless views of the beautiful coastline. Fringed by dramatic cliffs and sweeping casuarina trees, it's an ideal spot for a picnic, a game of beach cricket or to watch the Territory sun slip over the horizon at dusk. Depending on the time of year, you might see wading and migratory birds or nesting turtles on the beach. Heritage listed ruins from World War II are scattered through the reserve.
