Australia is intensifying its efforts to enforce a ban on social media use for children under 16 years old by doubling the maximum fines for violations to $99 million. The government has granted regulators greater authority to pursue major tech companies like Facebook and Instagram, which are accused of failing to adequately enforce the ban. Recent studies indicate that a significant majority of Australian children, about 80%, continue to access social media despite the restrictions, raising concerns about the effectiveness of the current measures. Experts emphasize the need for stricter enforcement and innovative strategies to combat tech giants and ensure compliance with age regulations.
