Giant sinkhole at a Queensland camping spot may have been a landslide

A giant sinkhole at a camping spot is now relatively
stable and may have actually been a landslide, a geotechnical engineer
says.
About 300 campers were evacuated from Inskip Point near
Rainbow Beach on Saturday night after the large cavity opened up and
swallowed a caravan, car, trailer and tents.

“Preliminary advice
is that the event may have been a ‘near shore landslide’ rather than a
true sinkhole,” the Department of National Parks said in a statement on
Monday.
The cavity is now about 200 metres long, 50 metres wide and up to nine metres deep.
A geotechnical engineer also advised the site is now relatively stable, with a flat beach edge forming.
Coastal
erosion is still occurring, so more trees may fall down, and the
exclusion zone has been expanded by 200 metres for safety reasons.

Camping grounds on either side of the site remain closed and
the public has been urged to avoid the area, observe traffic barriers
and warning signs.
All the school holiday campers escaped and no injuries were reported.
Geotechnical
engineer Allison Golsby said the area has a history of sinkholes and
should be closely monitored to warn of any further disasters.
She also said scientific reports indicate the entire peninsula could eventually fall away.
“People have said that at some stage they think Inskip Point may not be there,” she told ABC radio.
“Now that could be thousands of years; it could be hundreds of years.”
