Hi Ryan - you've probably already cottoned on to implementation of residential zone reforms in Victoria, particularly Melbourne's established middle-ring suburbs where application of the Neighbourhood Residential Zone has prevented increased density.  I imagine this dynamic between policies aimed at preserving heritage (however successfully) might come into conflict with urban consolidation agenda might be replicated elsewhere, too.  

There are also articles like the following by Glen Searle that look at how the consolidation agenda has divided communities and encountered an array of political obstacles: http://www.griffith.edu.au/__data/assets/pdf_file/0018/48600/urp-rp12-searle-2007.pdf  The interesting question that comes to mind is in what circumstances urban consolidation is desirable.

Best of luck with it!
