A massive sinkhole discovered near a beach in Australia's Queensland state has swallowed vehicles overnight, the media reported on Sunday.
The sinkhole, bigger than a football field and several metres deep, developed at Inskip point near Rainbow beach around midnight, ABC reported.
A car, a caravan, a camper trailer and tents were swallowed almost immediately.
Queensland Parks and Wildlife Services (QPWS) said the 150-metre sinkhole is three metres deep and takes up a large part of the MV Beagle campsite.
Holiday-maker Casey Hughes said the sinkhole "sounded like a thunder noise" as it opened up.
Fellow camper Sylvia Murray said "it was amazing to see".
Senior ranger Dan Clifton said there is a possibility the sinkhole could get bigger.
"There is a real possibility the hole could expand with ocean currents, so people are urged to avoid the area," Clifton said.
