- The document discusses 10-year plans that over 340 US cities and communities have implemented to end homelessness, which are supported by the US Interagency Council on Homelessness. - Key components of successful 10-year plans include political leadership, evidence-based initiatives like affordable housing and support services, and a focus on the most vulnerable populations. - Results from various cities show reductions in street and chronic homelessness ranging from 6.5-70% after implementation of a 10-year plan and increased housing and services. - While not all aspects have been successful, the overall concept and goal of ending homelessness through coordinated long-term planning is effective and could be adapted for use in Australia.
