Australia’s home for marathon and long distance swimming since 1973
Marathon Swimming Australia is the national home for marathon and long-distance open water swimming. We exist to recognise, support and celebrate every marathon swim of 10 kilometres and beyond, from first-time achievements to iconic crossings in oceans, rivers and lakes across Australia and around the world.
As the trusted custodian of Australia’s marathon swimming legacy, MSA independently ratifies swims, upholds safety and integrity standards, and preserves the stories and records that define our sport. By aligning with global best practice and reflecting the unique challenges of Australian waters, we ensure every swim stands proudly as part of a lasting national record.
Have your marathon swim officially recognised and recorded. MSA provides a clear, transparent ratification process that ensures your achievement becomes part of Australia’s permanent marathon swimming legacy.
