Volunteers are expected to be out in numbers this morning, looking for five-year-old Jack Dixon.

It's four days since he was swept out to sea by a rogue wave, but volunteers aren't giving up hope of finding his body.

Teams of lifesavers are rostered to help look for him, while the official police search has been scaled back.

Officers say they'll reassess the situation daily, and they're urging people planning to get involved this weekend to take extreme care around the water.
