long sinkhole at Inskip Point swallowed on Saturday a car,
caravan, camping trailer and tents. The erosion of the sand banks
started that night, said fishermen and campers who also saw trees
collapse into the water.
accident happens at a busy time for the popular camping ground in
Queensland with students on school holiday, reports Brisbane Times.
Ranger Dan Clifton estimated the time it happened between 10:30 pm
and midnight when sandbanks collapsed. Clifton describes the sound as
like “when you are on the beach and the tide is coming up into a
creek and the banks of the sand just drop down into water.”

and go to safer grounds. The accident resulted in closure of at least
half of the MV Beagle Campground. Camp operators evacuated about 140
campers and have cordoned off the sink hole areas, while they asked

said that the Queensland Parks and Wildlife Service would hire a
geomorphologist to investigate how the sink hole evolved.
Besides swallowing the caravan, trailer, vehicle and tent, the
sinkhole also claimed 200 metres of beachfront and 50 metres of

radar to assess the surrounding area.
are many reasons that this could occur, but there appears to be
elements of a slip or slump failure here, rather than just a
sinkhole-type behaviour,” says Geotechnical engineer Allison
