Fatal shark attacks make news, but 'dozens' of bites are not reported
The call comes as a 16-year-old boy remains in a serious condition in the Gold Coast University Hospital after he was mauled by what was believed to be a two-metre-long bull shark at Cabarita, on the New South Wales far north coast on Sunday.
Gold Coast-based shark researcher Dr Daryl McPhee said attacks were more frequent than people realised, because minor incidents were often not reported.
Mauling survivor Dave Pearson encouraged more surfers to report minor run-ins, to create a more accurate understanding of shark behaviour.
Authorities conceded that without diligent reporting of shark encounters, there was no way of knowing how often attacks occurred.
Dr McPhee, who is an associate professor of environmental science and Bond University, said he knew of minor attacks that went unrecorded.
"You can never work out exactly how many, because by definition they are unreported, but it certainly does occur," he said.
"They have happened in the ocean from divers poking or prodding something they shouldn't have poked or prodded, and then getting nipped and being a bit embarrassed by it."
A surfer was bitten in the Gold Coast's Tallebudgera Creek in September last year and took himself to hospital with arm injuries.
According to Queensland Health, five people have been treated for shark bites at Gold Coast hospitals in the past five years, but only two of them arrived by ambulance.
In that time, only three incidents across the region — including the deadly 2020 attacks at Greenmount and Kingscliff, as well as the recent close call at Cabarita — made headlines.
The Australian Shark-Incident Database (ASID) is the most comprehensive source of shark-bite information, and includes more than 1,200 cases dating back to 1791.
The database is run by the Taronga Conservation Society with Flinders University and the New South Wales Department of Primary Industries.
For an incident to be included in ASID, there must be an attempt by the shark to bite a person either in the water or on a small non-motorised craft like a surfboard or kayak.
Analysis of the data found the number of bites in Australia each year more than doubled between 2000 and 2020.
Marine biologist and ASID project lead Madeline Thiele said the leading hypothesis was that the increase was driven by human population growth, along with the popularity of surfing and diving.
Others believed the growth in shark numbers was to blame.
Some shark-attack victims said the official statistics failed to capture incidents where surfers were knocked off their boards or chased out of the ocean.
While such cases did not involve bites, survivors said the terrifying encounters should be recorded so authorities have a better understanding of shark behaviour.
Dave Pearson almost lost his arm to a bull shark 14 years ago at Crowdy Head, about an hour south of Port Macquarie.
He said his attack was almost identical to the one at Cabarita on Sunday.
Then aged 48, Mr Pearson was knocked off his surfboard close to shore, pulled under by his arm, and then followed by the shark after the encounter.
The quick thinking of other surfers who came to his aid and applied a tourniquet saved his arm.
He never goes to the beach without a first aid kit and hands out tourniquets to other surfers at his local break.
To help process the trauma, he founded Bite Club, a support network of shark attack survivors that now has 500 members worldwide.
They share a close bond and keep in touch regularly.
Mr Pearson said surfers and ocean swimmers were "certainly reporting a lot more sharks than we used to see".
But, he said, there were many reasons why surfers chose not to report coming face-to-face with sharks, including a desire to not scare others, or harm tourism in their town.
For a lot of people, however, the only way they could get back in the ocean was to forget the experience and pretend it never happened, he said.
"But people need to be made aware of the amount of sharks out there so we can prepare for it."

Childcare provider cancels meeting amid confusion for parents caught up in alleged sex offences saga
Parents say they are angry after a childcare giant that employed alleged child sex offender Joshua Dale Brown claimed police asked that a meeting with families be cancelled, amid frustration from other parents who have been asked to get children tested for sexually transmitted diseases a second time. Warning: This story contains details of alleged child sex offences which may distress some audience members. But Victoria Police have denied advising childcare operator Affinity Education to cancel the Thursday night meeting at the Papilio Early Learning Centre in Essendon. In an email sent to parents on Thursday afternoon, and obtained by the ABC, Affinity said: "As the investigation is still open, we have been advised by the police that there is nothing further to share at this time and therefore the meeting has been postponed." "We understand how distressing this is and that you may still have unanswered questions." A parent at Papilio Essendon told the ABC they were desperately seeking more information from centre management. "It's chaotic for sure," they said. "At the moment we know as much as the general public and that's the source of frustration." A police spokesperson told the ABC: "Victoria Police did not advise Papilio Essendon to not go ahead with the planned meeting." "Victoria Police has given no instruction to impacted childcare centre operators regarding their meetings with families. That is up to centre operators to determine and organise as they see fit," they said. Meanwhile, parents at other centres where Mr Brown worked are furious at what they say is a lack of clear communication from authorities, leaving them feeling they cannnot "trust the Health Department advice". The department said on Wednesday its highest priority was the health and wellbeing of the children, as reports emerged that families had received conflicting screening advice, meaning their children might need to be tested twice. Two families at Williamstown's Only About Children received texts recommending their children be tested for gonorrhoea and chlamydia on Tuesday, only to receive another message also recommending syphilis screening two days later, according to media reports. "We acknowledge this is an extremely distressing time for everyone involved, and regret that this family faced additional stress and anxiety," the department said in response. Another parent at the Williamstown centre told the ABC they proactively had their child tested for all three illnesses. They said their child had been recommended for gonorrhoea and chlamydia screening, while others enrolled at the same centre at the same time were being told to also test for syphilis. "A number of other families took matters into their own hands and did the same, and also tested for HIV and other diseases, because they realised they couldn't trust the health department advice," the parent said. The parent criticised what they characterised as a "bungle" by the health department. "They have had weeks and weeks of working with the police to get things right and yet they still stuffed it," they said. "They clearly learned nothing from COVID." Mr Brown, 26, of Point Cook, faces more than 70 charges including sexual penetration of a child under 12 and producing child abuse material relating to eight alleged victims at Creative Gardens Early Learning Centre in Point Cook between April 2022 and January 2023. He also worked at several Affinity centres including Papilio in Essendon, which was his last-known employer before he was arrested in May. Affinity did not comment when asked about the cancelled meeting. According to information released by the Victorian government on Tuesday, Mr Brown worked at Papilio Early Learning in Essendon between February 17 and May 9 this year. The government said he had also worked at the Only About Children in Williamstown between October 28, 2020, and March 30, 2021. This week, Affinity said it was re-examining its records to see if Mr Brown worked for it on additional dates to those so far publicly disclosed, after the ABC approached the company with evidence he was at a different centre on a date not included on the government's list.

CSIRO develops landmark framework to protect deep sea ecosystems
In the face of calls from around the Pacific for a moratorium or a complete ban, there's a new twist in the ongoing debate over deep sea mining. Australia's peak scientific body the CSIRO has developed the first environmental management and monitoring frameworks designed to protect deep sea ecosystems should the International Seabed Authority allow mining to go ahead. The project was commissioned by the Canadian exploration corporation, The Metals Company... and the research findings are based on its test mining activities in international waters known as the Clarion-Clipperton zone.
