Geotechnical investigations into 'sinkhole' begin
GEOTECHNICAL engineering consultants have begun further investigations at the site of the beach collapse near Inskip Point.
The Queensland Parks and Wildlife Service engaged EGD Consulting to study the underlying causes of the instability affecting the eastern section of the Sarawak campground to provide guidance on how to manage the area into the future.
The beach collapse made headlines around the world on September 26 when a landslide 200 metres wide occurred about 10.30pm.
About 300 campers were evacuated from the site, but a car, caravan, trailer and some tents were sucked into the ocean.
A QPWS spokesman said the studies would consider both onshore and offshore factors.
"Consultants are using laser, sonar and aerial surveys," the spokesman said.
"A geotechnical expert was engaged for the initial on-site inspection and assessment on Sunday, September 27, and supplied an interim report to QPWS on September 29, advising that as tidal actions deposit sand back into the hole caused by the landslide, the area would become more stable.
"Hydrographic and side sonar surveys from a vessel which maps the near-shore slopes were completed by Port of Brisbane Pty Ltd Hydrographic Solutions between 15 and 17 October."
The spokesman said the final report from EGD was expected on November 9.
Although Inskip Point is managed for a maximum of 2750 campers, the closures have temporarily reduced capacity to 2000.
"Depending on the outcome of the report, we may be able to do a staged reopening of some areas that are currently closed," the spokesman said.
"Safety is our first priority and the study will help us determine how to best manage the area to reduce the risk to visitors."
The MV Beagle campground and the eastern section of Sarawak campground remain closed and the public should avoid these areas.
The remainder of the recreation area is open.
