Typically, the number of properties advertised for sale in spring climbs as vendors look to take advantage of the warmer climate and improved weather.
CoreLogic takes a look at how the spring sales are tracking for this year. 
As housing market conditions transition, stock levels remain tight across the strongest markets but are rising in areas where housing market conditions are softening.
The analysis was measured the amount of advertised stock on the market on a rolling 28 day basis.
Advertised stock levels provide a unique count, meaning that listings are matched to properties and when a property is advertised in more than one place it is only counted once.
It’s important to note that typically these counts are more reflective of the established housing market rather than off-the-plan where stock often isn’t individually advertised.
• Across the nation CoreLogic is currently tracking 226,007 properties advertised for sale which is -5.3% lower than a year ago and well down on levels at this time of the year for the past five years.
• Across the combined capital cities, total stock advertised for sale is 1.0% higher than it was a year ago with 110,909 properties advertised over the past 28 days. Looking at stock at this time of year across the combined capital cities there is more stock currently for sale than there has been each year since 2013.
By comparing capital city and national data it indicates that the amount of stock for sale in the regional markets is substantially lower than it has been over recent years.
The combined regional markets account for 50.9% of total listings, its lowest proportion of national listings since December 2011.

Across the individual capital cities the data varies quite substantially.

• Melbourne – with 30,570 properties advertised for sale stock levels are 1.7% lower than a year ago. The volume of stock for sale is lower for this time of year than any of the past 5 years.
• Brisbane – the number of properties advertised for sale is 2.5% higher than a year ago with 20,611 properties currently on the market. Compared to this time of year over the past five years, listings are at their highest level since 2012 however, they are -15.2% lower than 2012 levels.

• Hobart – with 1,157 properties for sale across the city the volume of stock for sale -33.6% lower than a year ago and at its lowest level over each of the past five years. In fact Hobart stock for sale is -54.7% lower than it was two years ago.

Listings trends vary significantly across the country.
As an example, Hobart, which is the housing market with the strongest value growth has seen a dramatic fall in listings over recent years. 
Meanwhile, values have fallen over the year in Perth and Darwin and each of these cities is seeing heightened stock levels.
Sydney has seen a rapid slowdown in growth over recent months and at the same time the volume of stock for sale has increased relative to recent years.
In Melbourne, value growth remains relatively strong (although it has slowed a little) and the volume of stock for sale remains lower than over recent years.
The findings highlight that the stock for sale (supply) does have a fairly significant impact on the change in dwelling values.
As stock increases, growth slows and as stock falls growth has accelerated.
