Data from the states public planning registers and licence rolls
1573 suburbs had at least 5 residential building applications in the last 12 months, 57502 applications in all. After each suburb name is the postcode and the count for those 12 months.
Source: the public planning registers of the NSW government. A suburb with fewer than 5 applications does not get its own page, because one or two applications cannot carry the sentence about what gets lodged here.
