A “sinkhole” the size of a football field has opened up at Jumpinpin beach on North Stradbroke Island.
Surf Life Saving Queensland is warning swimmers to stay away from the hole which is reportedly around 100 metres wide.
The area is a popular fishing spot, but luckily no one was on the beach at the time the hole appeared.

Earlier this year, a near-shore landslide at Inskip in southern Queensland was originally thought to be a large sinkhole.
Sinkholes occur when water becomes trapped in rocks below the surface, causing a buildup of carbon dioxide gas that makes cavities in the rock.
The weakness of the rock puts stress on the underlayer, helping the cavities grow and creating a sinkhole.
