The Australian land development sector faces increasing pressure to deliver sustainable and resilient stormwater management solutions that comply with stringent regulatory requirements. Current industry practices often involve complex, time-consuming, and fragmented workflows, relying on a combination of qualitative and quantitative modelling approaches and disparate software tools and sources of data. This can lead to significant challenges for consultants, land developers, and councils, including extended project timelines, the need for specialized training, frequent inaccuracies in results, and difficulties in construction and challenging long-term documentation and maintenance. These inefficiencies can ultimately contribute to heightened risks of water pollution and flooding. This paper presents an overview of the existing stormwater design process in Australian land development, highlighting the key challenges encountered by stakeholders. Furthermore, it explores the potential of innovative software interfaces and integrated platforms to optimize qualitative Water Sensitive Urban Design (WSUD) and streamline it with quantitative hydrological modelling processes. By unifying these traditionally separate workflows, leveraging advancements in modelling techniques, and enhancing user accessibility, the proposed innovations aim to significantly improve efficiency, accuracy, and long-term sustainability in stormwater management for land development projects across Australia. This streamlined approach promises to reduce project costs and timelines, enhance the reliability of design outcomes, simplify documentation and maintenance, and ultimately contribute to better environmental protection and reduced flooding risks in urban and developing areas.
