Earthsharing Australia, in collaboration with Prosper Australia and the Land Value Research Group (LVRG), has put together the Speculative Vacancies in Melbourne: 2012 Report, authored by Philip Soos. The report is formulated from water usage data provided by City West Water and Yarra Valley Water to estimate property vacancies in the Melbourne area.
Earthsharing Australia has been producing the Speculative Vacancies report annually since 2008. The report classifies a vacant property as real estate showing water consumption less 50 litres per day (50L/d) averaged over the six months period, July-December 2011.
