Start Cup Day in the bay.

Williamstown Beach, near the Crystals Steps off The Esplanade. Check-in is on the sand from 7:30am — look for the club tent and the yellow caps. Street parking around The Esplanade fills quickly on a public holiday, so give yourself extra time.

You need to register with the club, but you don't have to join. Everyone who enters sets up a Hello Club account and signs the waiver — that's free, takes a couple of minutes, and it's how we know who's in the water. Paid membership is a separate step, and it's optional.

Until Monday 12 October entries are open to members only. From that date anyone can enter.

If you do want to join, membership is $80 per calendar year and charged pro-rata — so signing up now costs less than $25 for the rest of 2026, before it resets to the full $80 in January. That takes $10 off your Cup entry and $10 off every Saturday swim group, so the entry discount alone claws back more than a third of it on Cup Day. Register or join here.

Only over-18s can register themselves. Anyone under 18 is entered by a parent or guardian, who registers, signs the waiver and books through a linked child profile on their own account. What's involved depends on their age.

• 18+ Register and book yourself. Nothing extra needed — straight through online.
• 16–17 A parent or guardian does the whole thing. Register and sign the waiver, add your child as a linked profile, then book on their behalf. When you add the profile, use the club registration link while already logged in to your own account — don't start a second account, or you'll end up with a duplicate.
• Under 16 Same setup, plus a recommendation from their coach. Ask your child's swimming coach for a short written recommendation that they're ready for an open water swim over the distance you're entering, then email it to admin@melbourneopenwaterswimmingclub.org with their name and email address. Please get the recommendation from the coach yourself — we don't chase coaches, and we can't add your child to the event without it. Once we have it we'll add them by hand, so don't leave this to the week of the swim.

Distance minimums apply whoever does the booking: 12 and over for the 800m and 1600m, 15 and over for the 2400m and 3200m.

Parents and guardians are expected to actively supervise their children at this event and at every club swim group — on the beach and while they're in the water. Entering your child isn't the same as handing them over to us, and our water safety crew are watching the whole field rather than any one swimmer.

The 800m would be best suited for your first swim. That said, open water should not be treated lightly, even in calm and warm conditions.

We encourage you to attend a few practice swims first — the club's 8am Saturday class at Williamstown covers sighting, breathing and getting comfortable in chop.

Alternatively, please call us on 0487 678 787 for more information if you are not sure.

Yes. Wetsuits are welcome at every distance, and plenty of swimmers wear one. The only thing that would change that is the water being too warm — and in early November the bay is still coming up from winter, so it's very unlikely to come up.

The call is made on the morning from the measured water temperature and announced at the 8:50am briefing:

• 24°C+ Wetsuits not permitted. Too warm to shed heat while you're working. Wearing one brings a real risk of overheating, dehydration and dizziness, and dizziness in open water is dangerous.
• 22–23°C Allowed, but think about it. You don't need one for warmth. If you wear it for buoyancy, keep your effort down and get out if you start feeling hot or light-headed.
• Under 22°C Wear one if you'd like. The usual November range, and entirely your call either way.

If you're unsure how you handle cold, the club's open water temperature guide is worth a read before you decide.

Conditions and EPA water quality advice are checked in the days before the swim. If either makes the swim unsafe we postpone to a fallback date rather than cancel outright — that's what happened in 2025. Entered swimmers are notified by email and through the club's channels.

The winner of the Superfish wave. Superfish is the championship field — 3200m, seeded, off the beach first, and the only wave with the Cup on the line. Every other distance, including the standard 3200m, has its own first, second and third, but not the trophy. So if you can hold under 1:40 per 100m and you want a shot at it, enter Superfish rather than the standard 3200m.

No. There are no age categories and no gender categories at any distance. Each distance is one field, and we award first, second and third overall — decided on finish order, first three across the line. If you're 14 or 74, you're in the same result as everyone else who swam your distance. The one split is at 3200m: the standard 3200m and the 3200m Superfish are scored as separate fields, each with its own 1-2-3, even though both cover the same four laps. The Cup goes to the Superfish winner.

Not officially. Placings are taken from the finish order rather than the clock, so bring your own watch if you want a time and we can verify it at the finish.

Yes, and we need the help. Marshals, kayakers, check-in and beach crew all make the morning work. Email admin@melbourneopenwaterswimmingclub.org and tell us what you'd like to do.
