No single law in Australia protects an individual’s right to light. Instead, each state and territory has its own set of laws and regulations that deal with this issue.
In general, the right to light is a common law right that allows landowners to enjoy the natural light that falls on their property. This right is not absolute, and other landowners have the right to build on their property, even if it means that some of the light that previously fell on a neighbouring property is blocked.
However, there are some circumstances in which a landowner may be able to take legal action to protect their right to light. For example, if a new development blocks so much light that it makes the neighbouring property uninhabitable, the landowner may be able to sue for damages.
