Watt was warned about algal bloom weeks before seeking advice
South Australian Labor MPs were sounding the alarm about the state's toxic algal bloom weeks before Environment Minister Murray Watt inspected the affected areas and more than a month before he requested financial support options from his department. The toxic outbreak fuelled by above-average sea temperatures has killed tens of thousands of marine creatures since February, and, scientists say, 'led to mass mortalities of 278 marine species'.

CSIRO breakthrough could block sexualised AI deepfakes
CSIRO researchers say they've developed a new algorithm that can block images from being used to create deepfakes, as Australian state governments scramble to criminalise sexually explicit AI-generated content. The use of generative AI deepfakes to create non-consensual sexualised deepfake images has soared in popularity among high school students and the broader public. Victoria banned image-based sexual abuse in 2022, and the NSW and South Australian state governments are following suit.

The technique, developed by CSIRO in partnership with the Cyber Security Cooperative Research Centre and the University of Chicago, subtly alters content to make it unreadable to AI models while remaining unchanged to the human eye.

CSIRO breakthrough shields against sexualised AI deepfakes
CSIRO researchers say they've developed a new algorithm that can block images from being used to create deepfakes, as Australian state governments scramble to criminalise sexually explicit AI-generated content. The use of generative AI deepfakes to create non-consensual sexualised deepfake images has soared in popularity among high school students and the broader public. Victoria banned image-based sexual abuse in 2022, and the NSW and South Australian state governments are following suit. Now, a scientific breakthrough developed by Australian researchers could stop a user's photos from being used to create deepfakes altogether. The technique, developed by CSIRO in partnership with the Cyber Security Cooperative Research Centre and the University of Chicago, subtly alters content to make it unreadable to AI models while remaining unchanged to the human eye. The method could not only help block deepfakes but it could also help artists protect their work from being used to train AI, as debate rages locally about whether copyrighted material should be used to train large language models. Last week, the Productivity Commission announced it was investigating how AI models could be more easily trained on Australian copyrighted content, a move that prompted an outcry from the creative industry. CSIRO's algorithm could also help defence organisations shield their sensitive satellite imagery from being absorbed into AI models, for example. CSIRO research scientist Dr Derui (Derek) Wang said the technique changed an image's pixels so that it could not be used to train artificial intelligence models. He said it provided a mathematical guarantee that this protection held even against retraining attempts.
