Cost of works is the applicant's own estimate as lodged, so this reports the median rather than a total: the feed contains keying errors large enough to make sums meaningless — the biggest is $1,111,111,111,111 against alterations to a house, and 22 applications state a cost above $1,000,000,000 and are excluded here. Types with fewer than 20 applications are left out, because a median of a handful is noise. Source: NSW Planning Portal — Online DA open API, Creative Commons Attribution 4.0.
