Imagine that Australia is a giant puzzle, and cadastral divisions are like the pieces of that puzzle. These divisions are basically ways of dividing up the land in Australia into smaller, more manageable pieces.
Each piece is called a 'parcel', and it has its own unique boundaries that separate it from the other parcels around it. Sometimes these boundaries are marked by fences or natural features like rivers or mountains.
These parcels are really important because they help people identify what land belongs to whom. For example, if your family owns a parcel of land, you'll need to know exactly where it is, so that you can look after it properly and nobody else can claim it as their own.
The cadastral divisions in Australia are managed by different government agencies depending on the state or territory, but they all have the same basic purpose of making sure that land is used and managed in a fair and controlled way. In other words, cadastral divisions are like a map that helps everyone understand who owns what, and how we can all use the land responsibly.
