GOLD Coast beach goers are being assured, there is no major risk to the public after a sinkhole appeared at the Spit.
The giant pit emerged under the jetty on Saturday.
The Gold Coast Waterways Authority (GCWA) issued a statement on Sunday, insisting it was just part of “normal operations of the Sand Bypass System”.

“A number of factors contributed to the creation of the escarpment and the Sand Bypass System jetty structure is designed to accommodate such events,” GCWA CEO Hal Morris said.
“A combination of events including a low tide created the perfect environment for the creation of the escarpment when the jet pumps commenced operations on Saturday,” he added.
“The Sand Bypass System has been operating for almost 30 years pumping sand from the south side of the seaway entrance and depositing it on the beach on South Stradbroke Island.
In doing so it has contributed to the safe navigation of the Gold Coast Seaway by ensuring deep water is provided for the safe passage of vessels through the seaway entrance.”
The Sand Bypass System was the first of its kind in the world when it was constructed in 1986 together with the development of the Gold Coast Seaway entrance.
