I have posted previously on the residential land development activity profiles from the Qld Government Statistician (OESR). These were initially presented at an OESR regional roadshow back in 2011 which I attended and subsequently posted. These profiles provide an interesting perspective on building approvals and activity.
They have been updated since but don't think I posted as I have just discovered a previously unposted draft from last year. This is the table for the most recent data to the September quarter 2012 which tracks the stock of approved residential building lots. While the outstanding approved stock is below the peak in 2007 it remains substantial, and is also above Townsville at September 30.
