A Queensland council has urged tourists and residents to tread with caution after a potential sinkhole was discovered underwater at a popular beach.

Gladstone Regional Council issued a warning on their Facebook page on Friday after being alerted by a tourist that the giant hole was developing at the low tide mark at Seventeen Seventy on the Central Queensland coastline.

"Council advises there’s a potential sink hole just below the low tide mark at Seventeen Seventy," they wrote.

"A tourist staying across the road has seen it developing over the past three days and alerted our staff."

The council has erected two signs on the beach, located in front of Endeavour Park located to the left of the peninsula, in a bid to warn beachgoers of the danger.

The council also confirmed they are monitoring the ongoing situation and will reveal any updates via social media.

Several users voiced their concerns over the development, worried it could cause significant damage to the idyllic holiday location.

"This sink hole better not swallow up our most favorite holiday destination!" one user wrote.

"That is frightening, hope it doesn't get as big as Inskip point sink hole," another commented.
