In a sense if that is the major complaint then it makes sense why they are getting relected - developers are taking land and building things people want. There has always been a background level of corruption in construction afaik. Everyone wants it to be a squeaky clean process, but everyone also wants infrastructure; we have high immigration and we need the groundwork laid in Sydney to support population growth.

We can argue about whether they are making great long term decisions. They probably aren't. But there is a lot of activity in the right general space; they took political risks with their light rail build up for example. And the recent Federal Labor party has a questionable record at infrastructure projects and it seems unlikely that the NSW branch has a better handle on the situation.
