A section of beach that fell into the sea on North Stradbroke Island is starting to reappear.

Sand is already returning with the tide to the site next to Jumpinpin channel, according to the Queensland Parks and Wildlife Service (QPWS).

However, swimmers are still being advised to keep away from the area, which was initially described as a sinkhole the size of a football field.

QPWS southeast regional director Mick Cubis said rangers had inspected the site of the “sand slump” on Thursday.

“It’s an area where the sand is constantly shifting, and sand is already returning with the tide, Mr Cubis said.

“Queensland’s coastal sand masses are dynamic environments and change all the time due to wind, tides and waves.”

In September a hole swallowed a caravan, car trailer and tents further north at Inskip Point, near Rainbow Beach.

However that event was described as a “near shore landslide event” rather than a true sinkhole.
