Although it has only been in the last 10 years or so that the internet has really penetrated my life, it's now hard to imagine how I survived before it. But when it comes to parenting, it's pretty much a new frontier. As my four children grow up with this technology, the best thing I can do is educate myself about the dangers they might face online.

To be honest, I'm not all that interested in technology. But my children are moving at a faster pace, and there's been a big increase in primary school-aged kids accessing new technologies.

Greg Gebhart is an educator from NetAlert, Australia's internet advisory body. He urges parents to be aware of what their children do online. The biggest growth is in social networking sites such as MySpace, Bebo, Facebook and YouTube. These are like an online diary. People create profiles with personal information and pictures, then form online networks of friends.

Younger teenagers tend to be vulnerable with these sites,
as they don't realise the extent or the permanence to which they are exposing themselves. 'Once personal information or photos are posted on the net, they're there forever. Young teenagers believe the world they've created will only be viewed by their friends, but many adults visit these sites,' Greg says.

When it comes to safety online the big concerns are stranger danger, exposure to illegal and inappropriate content and cyber-bullying. Content filters play a part in controlling what a child is exposed to online, and this year the Federal Government announced a scheme to provide families with access to a free filter. However, filters only do so much. The most responsible course of action is for parents to be informed and develop a relationship with their children so they understand the risks. It's never too early to put safe practices in place.

Net Alert's safety tips for parents

• Learn how the different social networking sites work, so when you talk to your kids you can speak from experience.

• Check out your child's profile on the sites and modify it if necessary. Keep their personal information private.

• Find out the networking sites your children are using and ensure they're appropriate.

• Know the friends in your child's social network.

• Let your child know that if they see upsetting content on a site they should tell you.
