Across the combined capital cities, there is currently 5.3 months of housing supply available for sale.
If no more properties were advertised for sale it would take 5.3 months for current advertised supply to be purchased. 
For this time of year, this is the highest months of supply figure any time since 2012.
To put the figure into context, at the same time last year there was a much lower 3.9 months of supply.
The lift in months of supply is a function of a lift in the amount of stock available for sale and the ongoing fall in transaction volumes.
Note: The months of supply metric measures the volume of stock advertised for sale against the run rate of settled sales. The result, expressed in months, provides an indication about how long it would take the market to absorb all the residential properties that are advertised for sale.
