Coastal interventions are applied for modifying the equilibrium state of coastal processes in order to address coastal community's needs. In several cases, the issues caused by the introduction of one structure are solved by other engineering solutions, but also creates new side effects. Letitia Spit (Tweed Heads, NSW) is a typical example of long-term coastal management actions that led to new shoreline equilibrium. This paper aimed to outline the shoreline response of Letitia Spit to these interventions and identify the extent of the updrift impact through a long-term remote sensing analysis.Coastal interventions are applied for modifying the equilibrium state of coastal processes in order to address coastal community's needs.
