SHARK nets erected at three New Territories beaches are no guarantee of safety, a Regional Council shark prevention officer warned yesterday.
Chairman of the Regional Council's Ad-hoc Committee on Shark Prevention, Wan Yuet-kau, said the multi-million-dollar nets were still being tested, with results to be determined later this year.
The council bought shark nets for Silverstrand Beach and Clear Water Bay Beach at Sai Kung, and Kadoorie Beach at Tuen Mun, in May last year.
The effectiveness of the $8.9 million shark prevention nets will be gauged after two 'shark seasons', a period which ends in October.
Mr Wan said the council would not consider installing more shark nets until the revision was complete.
'We believe the nets are dependable - but we cannot say for sure whether they are 100 per cent safe, because the test season has not ended yet,' he said.
'Since no accidents have occurred in the beaches where the shark prevention nets have been installed, it could be said that the nets are effective.' A handful of swimmers ignored shark warning flags raised on Friday, immediately after the second fatal shark attack in the Silverstrand Beach and Sheung Sz Wan area.
