- Piara Waters, which accounts for about 8% of Armadale SA3, had 64% of the total number of new house approvals. In this case study, the ASGS has provided more detailed regional data than the ASGC. In contrast to Case Study #1, this example from Queensland shows the converse. Here, the region has changed from five sparsely 'populated' SLAs (ASGC) to one SA2 (ASGS). As per Case study #1, there is a perfect outer boundary match - which we must remind users - is not always the case. Map 2A: Number of New House Building Approvals by SLA, July-December 2011, ASGC Under the ASGC there were three SLAs based on Barcaldine and two based around Blackall. With the new ASGS, however, a single SA2 combines the two main centres - renamed as Barcaldine - Blackall. Map 2B: Number of New House Building Approvals by SA2, July-December 2011, ASGS For the five SLAs under the ASGC (Map 2A), Blackall Tambo (R) - Tambo had zero approvals, while Barcaldine (R) - Aramac and Barcaldine (R) - Barcaldine had one approval each, and Barcaldine (R) - Jericho and Blackall Tambo (R) - Blackall recorded three approvals each (eight new house approvals in total). The new Barcaldine - Blackall SA2 (ASGS) also recorded eight approvals. In this case study, the new ASGS provides a more consolidated SA2 region than the sparsely 'populated' SLAs. This case study is an example of where a Statistical Subdivision (SSD) under the ASGC covers an apparently similar geographic area
