Start your dolphin search by following the Kwinana Freeway south from Perth to Rockingham and the wildlife-rich waters of Shoalwater Islands Marine Park. From here, take a dolphin watch cruise to meet some of the 200 plus wild dolphins that frequently visit the area. Watch them playfully leap in the wake of the boat and listen to their clicks and whistles. You may also enjoy a bonus encounter with Australian sea lions, stingrays, pelicans and more. Grab some lunch at one of Rockingham's waterfront cafes before making the 20-minute journey to Mandurah .
