Imagine you and your friends are playing with toys in the playground. You've built a fort and claimed it as your own spot to play with your toys. But what if someone else came along and said, "Actually, this spot belongs to me and my friends. You have to leave." How would you feel?
This is kind of like what happened here in Australia when Europeans first arrived. They claimed the land as their own, even though lots of Aboriginal and Torres Strait Islander people had already been living here for thousands of years. This wasn't fair, because the original people had already established relationships with the land and had their own systems of ownership and control.
Fast-forward to today, and the Australian government recognizes that the land does not belong exclusively to non-Indigenous people. Instead, some land belongs to the Indigenous groups who have lived there for generations, and this is called 'native title.'
Here's a simple example: Imagine you and your family have been living on a piece of land next to a river for as long as anyone can remember. You swim and fish in the river, and you gather food from the land. This is part of your culture and heritage. But then, a big company comes along and starts digging up the land to build a factory. They don't ask your permission, and they don't offer to share any of the profits that they make. How would you feel?
Native title laws are in place to try and prevent this kind of thing from happening. Essentially, it gives Indigenous groups the right to claim ownership of land that they have a strong connection to. This doesn't mean that they can own all of Australia (because that would mean there would be nowhere for anyone else to live!), but it does mean that they can have a say in how the land is used and they can protect it from damage.
So, to summarize: native title is a legal concept in Australia that acknowledges the rights of Indigenous groups to claim ownership of land that they have a strong connection to. It is designed to give them a say in how that land is used and to protect it from damage caused by others who don't share the same cultural heritage.
