A car and caravan were sucked into the football field-sized sinkhole when it opened up on Saturday night.

More than 300 visitors were evacuated from camping grounds at Inskip Point near Rainbow Beach after the sinkhole swallowed 200 metres of the beach.

No one was injured when the sinkhole appeared, but tents and a camping trailer were also lost with the car and caravan.

Geotechnical engineer Allison Golsby told ABC Radio sinkholes were a frequent occurrence in the area.

“The ideal answer is, it is great to monitor because then we keep everybody in the right place and they won’t be put in a position like that,” Ms Golsby said.

Senior ranger, Dan Clifton told news.com.au they were advising people to take note of barricades put in place by rangers and police.

“There is a real possibility the hole could expand with ocean currents, so people are urged to avoid the area,” he said.

This is similar to a sinkhole that opened up in 2011, where there were also no people injured.
