A government report reveals critical flaws in selfie-based age-check technology ahead of Australia's social media ban for users under 16, set for December. Accuracy drops near the age cut-off, with 8.5% of users aged exactly 16 misclassified as underage. The report highlights increased error rates for non-Caucasian users and teenage girls. Communications Minister Anika Wells defends the trial's findings, emphasizing privacy but admits challenges remain for platforms facing potential AUD $49.5 million fines.
