Majority unprepared for quantum computing's security risks
The ISACA Quantum Computing Pulse Poll, which surveyed more than 2,600 professionals in fields such as digital trust, cybersecurity, IT audit, governance and risk, found that while awareness of quantum computing's transformative potential is increasing, concrete planning and readiness measures are largely absent from organisational agendas.
According to the poll, 62% of technology and cybersecurity professionals are concerned that quantum computing could break today's internet encryption, raising the possibility of vulnerabilities in digital signatures, websites, utilities and medical records. However, just 5% of respondents said that their organisation considers quantum computing a high priority for near-term planning, and only 5% report having a defined strategy for it.
Jamie Norton, ISACA Board Director, highlighted the accelerating pace of quantum computing and the significant implications for sectors that handle large volumes of sensitive data. He said, "Too many Australian and New Zealand organisations remain in reactive mode and underestimate quantum computing's potential to break existing encryption. Now is the time to assess whether you have the expertise to implement post-quantum cryptography solutions and start building internal capability. This is essential to mitigate its impact and protect sensitive data, maintain customer trust and ensure long-term business resilience."
The research underscores that many see potential for quantum technology to drive major advancements. Sixty-three percent of respondents expect quantum computing to significantly speed up computational tasks or data analysis, and 46% anticipate that it will lead to revolutionary innovation. Nearly half (48%) are optimistic about the impact quantum computing could have within their sector.
At the same time, respondents are alert to new risks, with 63% saying quantum computing will increase or shift cybersecurity risks. More than half (57%) believe it will create new business risks, 52% expect that it will change the skill sets required by businesses, and 50% foresee challenges around regulation and compliance. Among participants from Oceania, concern was even higher across all these areas by at least 10 percentage points.
A total of 62% of respondents expressed concern that quantum computing could break current internet encryption before new, quantum-resistant algorithms have been fully implemented. More than half (56%) cited fears around the so-called "harvest now, decrypt later" threat, whereby data is stolen now with the intention of decrypting it using quantum computers in the future.
Despite a quarter of poll respondents believing that quantum computing will have an industry-wide impact within five years, and 39% saying they expect it in six to ten years, many organisations are taking a wait-and-see approach. Forty-one percent report no plans to address quantum computing at this time and 40% are not aware of their company's intentions regarding quantum issues.
When questioned on the role of quantum computing in their current technology strategies, only 15% indicated it was on a long-term roadmap, while 19% had discussed it in some form but made no formal plans, and 37% had not discussed it at all. Nearly a quarter (24%) were unsure of their organisation's view on the matter.
The poll findings also point to significant knowledge gaps. Only 7% of respondents claimed to have a strong understanding of the new post-quantum cryptography standards developed by the US National Institute of Standards and Technology (NIST), while 44% said they had never heard of them.
Many organisations have yet to take decisive action to prepare for quantum computing. More than half (55%) have not started any preparatory steps. Of those that have, actions cited include: assessing regulatory or compliance implications (46%); exploring quantum-safe cryptography (38%); collaborating with quantum hardware or software providers (28%); training staff (27%); and investing in research and proof-of-concept initiatives (27%).
The poll also found that 30% of global cyber and IT professionals do not feel they have a good understanding of quantum computing's capabilities, highlighting the need for training and skills development in this area.
Rob Clyde, chairman, Crypto Quantique, and past ISACA board chair, advised that organisations begin preparing now. He said, "Start by 1) identifying where encrypted data are stored and devices that use encryption, 2) developing a plan to transition to post-quantum cryptography prioritising critical data and systems, and 3) continuously monitoring for updated software and firmware with post-quantum cryptography. Waiting until quantum computing is here is too late, especially given today's harvest-now, decrypt-later threat."

YouTube threatens to sue Aus govt if roped into social media ban
Google has been warned its threats to sue won't sway the potential late inclusion of YouTube in Australia's world-first social media ban for children. The tech giant wrote to Communications Minister Anika Wells declaring it was considering its legal position if its video sharing platform was included in the ban for children 16 and under. The letter, first reported by the Daily Telegraph, flagged the ban could be challenged on the grounds it restricts the implied constitutional freedom of political communication. Signals the Australian government was contemplating an "abrupt policy reversal" prompted Google to seek further clarity. "YouTube is a video sharing platform, not a social media service, that offers benefit and value to younger Australians," a YouTube spokesperson said. ADVERTISEMENT "We have written directly to the government, urging them to uphold the integrity of the legislative process and protect the age-appropriate experiences and safeguards we provide for young Australians." The social media ban is due to come into effect in December. Facebook, Instagram, TikTok and Snapchat were among platforms covered when legislation passed parliament. YouTube was exempted, in a move TikTok described as a "sweetheart deal". "The government was firm in its decision that YouTube would be excluded because it is different and because of its value to younger Australians," a YouTube spokesperson told AAP. "This intention was repeatedly made clear in its public statements, including to the Australian parliament." But e-Safety Commissioner Julie Inman Grant has recommended a rethink, citing research showing children were exposed to harmful content on YouTube more than any other platform. ADVERTISEMENT "The new law will only restrict children under the age of 16 from having their own accounts — not accessing content on YouTube or any other service through links from the school or in a 'logged-out' state," she told the National Press Club in June. "There is nothing in the legislation that prevents educators with their own accounts from continuing to incorporate school-approved educational content on YouTube or any other service just as they do now." Prime Minister Anthony Albanese took a dim view of Google's attempt to muscle in on the decision-making process. "The minister will make these assessments... independent of any these threats that are made by the social media companies," he told ABC TV on Sunday. "I say to them that social media has a social responsibility. "There is no doubt that young people are being impacted adversely in their mental health by some of the engagement with social media and that is why the government has acted." The early findings of an age-verification trial found technologies could block young kids from social media platforms, but not without loopholes. ADVERTISEMENT Platforms will face penalties worth up to AUS$50 million (NZ$54.5 million) if caught not taking reasonable steps to prevent children 16 and under from creating accounts.

ANZ Premiership final: Live updates as the Northern Mystics host the Mainland Tactix at Trusts Arena
The Northern Mystics and Mainland Tactix will meet for a third time this season in front of a sold-out Trusts Arena crowd to determine the 2025 ANZ Premiership title. Netball NZ update eligibility laws, opens door for overseas-based Silver Ferns The Netball New Zealand (NNZ) board has voted to update the eligibility criteria for national selection, allowing players based overseas to be available for the Silver Ferns. After reviewing the criteria, NNZ has introduced a formal exemption process to adapt to the changing face of the sport. Players presently choose between higher-paying opportunities overseas, or remaining in Aotearoa – where they can be eligible for the Silver Ferns. The new criteria will come into effect before this year's international netball season, with what the national organisation has described as 'clear guidelines and assessment measures for any exemption applications'. 'We've listened to the game and believe this is a positive step forward,' said NNZ board chair Matt Whineray. 'This update strikes a balance between flexibility and fairness, acknowledging the increasingly global nature of netball while continuing to protect the integrity of our domestic competitions and the mana of the Silver Ferns.' Players wanting to remain eligible for national selection while based overseas will need to go through a formal process, although the updated criteria has not been made available. 'Ultimately, the purpose of this proposed process is to ensure that all exemption requests are evaluated fairly, consistently, and transparently,' said NNZ chief executive Jennie Wyllie. 'It safeguards the athlete through a structured and transparent approach, while upholding the broader interests of Netball New Zealand, the Silver Ferns, and the ANZ Premiership competition.' NNZ has said the updated criteria will not be made public, adding to what has been a murky saga regarding overseas players' availability. Earlier this year, Silver Ferns captain Ameliaranne Ekenasio told Newstalk ZB that players must have 100 test caps to be eligible for an exemption to play offshore and still play in international fixtures. Australian-based Grace Nweke confirmed the same to Fox Sports - saying it was Netball NZ's 'black and white' rule. However, a spokesperson for the national body has clarified no such 100-test rule exists, and each case was at the board's discretion. In the time since, multiple players have expressed to Newstalk ZB that they have been forced to choose between overseas offers – largely out of Australia – and remaining in NZ and the ANZ Premiership.

Heather du Plessis-Allan: We are being irrational about the price of butter
Unless you're into commercial scale baking, butter is not the thing putting the most pressure on household budgets. Try power. This winter power is costing the average household almost a block of butter every day. Or rates. That's costing the average Wellingtonian more than a block of butter every day. Those expenses have no alternatives. You have to pay them. With butter we at least have alternatives. If we don't like the price we can do a swap. I don't want to be Marie Antoinette but at least we have the option to switch to margarine. Not only have we abandoned logic, but also facts. Even the Finance Minister briefly took to complaining that butter is cheaper in Australia than in the very country that produces it. Except that's not true. At the time of writing, if you take Woolworths' salted butter, which is available both sides of the Tasman, adjust for currency and the fact the Australian Government does not charge their equivalent of GST on butter, we actually pay 30c less. Discounting butter domestically is impractical, as it would require subsidies, impacting farmers and shareholders. Actually, the price of butter is a good news story for New Zealand. Because if we're paying our farmers more, the world is paying our farmers more. And they're buying a lot more blocks of butter than we are. So that means they're paying a good chunk towards our tax take, our health, our roads, our schools. It's become slightly fashionable to suggest the solution is to discount butter domestically. That's a nutty idea. A discount is a subsidy. A subsidy has to be paid by someone. Who? Fonterra? The shareholders will probably object to that. Maybe, if this drama runs on long enough and there is enough reputational damage to Fonterra, it might be in the business' interest to cut the price to make the pain stop. That would not be a good day for farmers and shareholders. Miles Hurrell attributes the 46.5% rise in butter prices to global demand and supply issues. Photo / Alyse Wright The Government? Again, bonkers. If New Zealand is too broke to afford the full Dunedin hospital build, we're too broke to help commercial bakers afford their butter. The truth is there is no fix to the price of butter that isn't stupid or temporary. We simply have to pay the price that we pay. And the Finance Minister knows this. She knows this because she is a very clever woman. And because she worked for Fonterra for six years. Finance Minister Nicola Willis has turned butter into the cost-of-living symbol. Photo / Mark Mitchell So, she should never have turned butter into the cost-of-living symbol she has. This really started with her in April when she visited Costco and was taken by the fact it could sell butter for about half the price mainstream supermarkets were selling it for. It became her evidence that supermarkets were ripping us off. But then somehow, Fonterra got dragged into it and one of their regular ministerial briefings became a please-explain. And then the TV news was chasing the CEO Miles Hurrell around the forecourt of Parliament and going live to air while the meeting was under way. And there were expectations. And then nothing happened. And it has become yet another example of the Finance Minister, disappointingly, talking big but doing nothing. Just like with the retail banks. And just like with the supermarkets, so far. Spare a thought for Hurrell. The man is one of the most impressive Kiwi CEOs of his generation but had to spend his week cast as the villain of the butter story. There is no story. It's not even the biggest pressure on our weekly bills.
