Who Owns Improvements On Someone Else's Land? Why It Matters For Major Projects

Billions of dollars are invested each year into assets constructed on land owned by someone else—whether for renewable energy projects, major infrastructure projects, logistic and transport projects (such as airports and ports) or residential and commercial developments on Australian government-owned land. These projects often involve complex leasing or licensing arrangements. But a critical question is often overlooked:who owns the improvements once they are built?
