Modular construction is increasingly recognized worldwide as an efficient and sustainable alternative to conventional building methods. In Australia, modular building systems have been successfully implemented to address housing shortages, rapid urbanization, and disaster relief efforts. The integration of deployable modular systems further enhances these benefits by enabling efficient transportation and rapid on-site assembly, thereby improving flexibility and resilience in urban construction. Conversely, Indonesia faces significant challenges in adopting modular construction due to regulatory constraints, economic limitations, and a shortage of skilled labor. This study conducts a comprehensive review of current modular construction practices in both Australia and Indonesia, accompanied by a comparative analysis of the regulatory frameworks, available resources, and construction methodologies in each country. The objective is to identify key challenges and opportunities for advancing resiliency in urban and post-disaster housing solutions. Furthermore, this study proposes a conceptual design recommendation tailored to post-disaster housing reconstruction in Indonesia. By incorporating deployable module systems, the proposed approach aims to address the demand for adaptable housing solutions that transition from temporary to permanent use, minimizing the need for extensive reconstruction resources.
