Council workers found no holes in the netting, leaving the shark's entry point a mystery. Shark expert Dr Chris Pepin-Neff discusses the safety of netted enclosures, calls for standardised audits across Sydney harbour pools, and addresses concerns about funding and maintenance following a tragic summer of shark incidents.
