In 'Hospitality, Service, Proclamation', Tom Wilson seeks to demystify the interfaith project. Written for ordinands and those preparing to minister in neighbourhoods where interfaith and intercultural dialogue are essential, Wilson argues that rather than a threat to churches, interfaith dialogue is an important tool for discipleship.

Background: Population projections for Australia are produced by many organisations. They differ in projected population numbers, methods used, level of output detail, temporal extent, frequency of revision, quality and purpose, and they are not always easy to find. ; Aims: This paper provides a brief guide to many of the population projections prepared for Australia in recent years. It gives an overview of projection methods and selected results, a brief commentary on key aspects of the projections, and shows readers where to find more data and information. ; Data and methods: Projections data were obtained from the various organisations producing projections. They are presented in order of spatial detail: national scale, States and Territories; large sub-state regions; and then local and small areas. ; Results: The ABS and State and Territory Governments are the main producers of population projections and forecasts in Australia, and generally these projections are good quality. They cover a wide variety of spatial scales from the national level to local areas, such as SA2s. A great deal of projections data and information is now freely available online. Conclusions: Population projections and forecasts can be very useful data for a wide variety of planning, policy and research purposes. But it is important to be aware of their limitations.

Errors from past rounds of population projections can provide both diagnostic information to improve future projections as well as information for users on the likely uncertainty of current projections. This paper assesses the forecast accuracy of official Australian Bureau of Statistics (ABS) population projections for the states and territories of Australia and is the first major study to do so. For the states and territories, it is found that, after 10-year projection durations, absolute percentage errors lie between about 1% and 3% for the states and around 6% for the territories. Age-specific population projections are also assessed. It is shown that net interstate migration and net overseas migration are the demographic components of change which contributed most to forecast error. The paper also compares ABS projections of total population against simple linear extrapolation, finding that, overall, ABS projections just outperformed extrapolation. No identifiable trend in accuracy over time is detected. Under the assumption of temporal stability in the magnitude of error, empirical prediction intervals are created from past errors and applied to the current set of ABS projections. The paper concludes with a few ideas for future projection rounds.
