認識澳洲的網路安全衛士，他正在與社群媒體上的混亂作鬥爭，保護孩子們的安全。

Julie Inman Grant is the head of Australia's eSafety Commission, a group that works to keep people safe on the internet. Her job is especially important now because Australia has started a new rule that bans anyone under 16 from using social media. This means that teenagers younger than 16 are not allowed to have accounts on popular platforms like Facebook, Instagram, Snapchat, or YouTube. Julie's job is to make sure these rules are followed and to help protect kids from dangers online.

Julie has a lot of experience in the tech world. She grew up in Seattle, where big companies like Microsoft and Amazon are based. She worked for Microsoft and Twitter before moving to Australia. She noticed that while technology was growing fast, not enough was being done to keep people safe online. That's why she decided to work for the government and help make the internet a safer place. Now, as the eSafety Commissioner, she has to deal with a lot of challenges. She gets many mean messages and threats because some people do not like the rules she helps create. She has even had arguments with famous people like Elon Musk and has been criticized by politicians in other countries.

The new social media ban has made Julie's job even harder. Many parents in Australia support the rule because they worry about their children being bullied or seeing bad things online. However, some experts and child advocates think banning kids from social media is not the best solution. They believe children should be taught how to use the internet safely instead of being kept away from it. Some also worry that the ban could hurt kids who live in rural areas, have disabilities, or are part of minority groups, because these kids often find support and friends online.

Julie compares learning to use the internet safely to learning how to swim. She says that just like kids need to learn about water safety, they also need to learn about online safety. There are dangers online, like people who want to trick or hurt others, and kids need to know how to protect themselves. Julie has three children, including twins who are 13, so she understands how hard it can be for families to follow these rules. She says her own home is like a laboratory for testing how the rules work.

Even though the new law is controversial, Julie believes it is important to try new ways to keep kids safe. She works with the government and big tech companies to make sure the rules are followed. Some companies do not agree with the ban, but they have promised to obey the law. Julie also has to deal with legal challenges from companies like Reddit and from teenagers who do not want to be banned from social media.

Australia is one of the first countries to try such a strict rule about social media and kids. Some people in other countries think Australia is going too far, and Julie has been asked to explain the rules to politicians in the United States. She says her job is not to defend the law, but to make sure it is carried out fairly. Julie is also preparing for new challenges, like making sure artificial intelligence is used safely. She has been the eSafety Commissioner for almost ten years and says it might be time for someone else to take over soon. However, she still wants to help make the internet safer for everyone, in Australia and around the world.
