THE beach at Inskip Point will continue to disappear into the ocean, an expert says.
Associate lecturer and soil geoscientist from the University of the Sunshine Coast Peter Davies said underwater landslides similar to the one that occurred on Tuesday at Inskip Point would happen again.
He said the landslides occur because of the way ocean currents flowed in and out of the narrow channel between Inskip and Fraser Island.
The scientist explained that the fast-moving water caused erosion under the beach.
"It's just because you've got quite a small channel; it's only a kilometre or two to Fraser (Island), and there's lots of water going in and out there, so the currents are quite strong and the water's moving really quickly," Mr Davies said.
"That's a lot of erosive force..."
He said because the beach is "very young", about 10,000 years old, it was still very unstable.
"I'd suggest camping on the southern side, to avoid that massive northern current," he said.
"The sand position is constantly changing; where the massive landslide was before Christmas is now all but gone, you would hardly know it was there because it does repair itself."
A national parks and wild-life spokeswoman said the sand was re-filling the hole left by the latest landslide.
No campsites or the barge to Fraser Island have been affected.
