The Mount Martha Annual Diamond Swim (MMAD Swim) is one of the safest open water swims on the calendar with our 100 water safety personnel supporting swimmers.
Held at Mt Martha Beach in Mt Martha, Victoria, the event offers three swim distances including a 400m, 1.2km and 5km in an around the buoys course.
There is also a 200m Nipper swim for the kids, so why not make it a family fun day of ocean swimming.
