In 2026, Mount Martha Beach on the Mornington Peninsula has officially secured top honors as Victoria's cleanest and best beach. This 2-kilometer stretch of pristine white sand is celebrated for its crystal-clear, calm, and shallow waters, which are consistently monitored for high water quality. The beach is split into North and South sections by Balcombe Creek and is famous for its iconic, colorful bathing boxes that line the foreshore against a backdrop of lush wetlands and bluffs. Beyond its cleanliness, Mount Martha is a champion of accessibility, featuring beach matting to assist wheelchairs and prams. For visitors seeking a safe and immaculate swimming spot, the sheltered conditions created by a 200-meter outer bar keep the waves gentle, making it a favorite for families, stand-up paddleboarders, and coastal hikers exploring the nearby rock pools at The Pillars.
