Dozens of beaches along Australia's east coast, including in Sydney, closed on Tuesday after four shark attacks in two days, as heavy rains left waters murky and more likely to attract the animals.
Beaches around Port Macquarie, around 400 km (250 miles) north of Sydney, were shut after a man was bitten while surfing earlier in the day. He remains in hospital in a stable
condition, health authorities said.
"If you're thinking about going for a swim, think of going to a local pool because at this stage, we're advising that beaches are unsafe," Steven Pearce, the chief executive of Surf Life Saving New South Wales (NSW) told reporters on Tuesday.
"We have such poor water quality that's really conducive to some bull shark activity."
