The slowdown noted that apartment prices fell 7 percent in Sydney and 2 percent in Melbourne.
It has also provoked a gloomy forecast by analysts that the country's largest real estate developers – Mirvanc, Landlays and Stockland – are facing a greater risk of falling in neighborhoods and hitting their profits due to their exposure to projects sold to buyers at the 2017 peak the property cycle.
The property developer behind a 130-unit project in Epping is a little-known apparel called Gondon with links to a Chinese developer.
Gondon sold 69 apartments in the project, sold as setting up a "new standard in modern living" before the Newpoint receivers were called. They are deemed to be appointed from an offshore bank based in China.
A group of happy homeowners of Epping scored more than $ 26 million in the panoramic real estate market in 2016 when Gond set up for the aggregation of several suburban homes along Carlingford and Cliff Roads to compose a "super-lot" place for development.
Only the group's previous project in Australia was a housing block called Macquarie in North Rid.
Sales agents Colliers International and Newpoint declined to comment.
Copper units in Epping dropped 2.26 percent over the year to an average of $ 820,000, according to CoreLogic.
One bedroom apartment in Elisey was sold for $ 788,000, while double units ranged for $ 1.08 million before the project fell.
Loans by Australian banks have been reduced by 22 percent of their peak, as the big four tighten the investor's screws, raising the standard variable interest rates and increasing control of the borrower's applications.
The country's largest real estate players are facing an escalating risk from buyers who do not pay during settlement due to falling apartment and land prices, analysts say.
"We see Mirwack as the greatest risk followed by Landela and Stockland," said UBS analysts Grant McCasker and James Drucker.
The sale of the apartment represents a significant part of the Mirvac earnings, especially over the next three financial years. In 2020, nearly a third of the group's revenue will come from neighborhoods in Sydney and Melbourne.
The projects most at risk are in the Sydney Marrickville and the Olympic Park that "appear out of money," because the Sydney housing price index has fallen by 5% since the launch, analysts say.
St Leonards could also become a problem when prices fall another 5 to 10 percent.
"We are less concerned about the settlement risk of Lendlease considering the price increase from the launch dates 2015-16," said Mr McKasker and Mr Drucker.
Another major investor, Stockland, has minimal exposure to the apartment market, but is banking on significant revenue from the sale of land for new homes.
The number of buyers who terminate land purchase contracts is currently low, but the UBS warns that tightening of credit, falling prices, incentives and reduced deposits will increase the number of buyers who are struggling.
There was a documented increase in speculative land buyers trying to deliver their contracts for the purchase of Gumtree and other sites, which increased the risks.
"We expect settlements in the second half of Stockland to disappoint, as increases in cancellation rates and settlement times," UBS said.
Property experts believe that there is more pain to come to this sector.
The same SQM Research analyst Louis Christopher said that, despite the recent downturn, the property market Sydney and Melbourne are still overestimated.
"This crisis still has some legs to run yet," he said on Tuesday.
"Sydney and Melbourne remain heavily overextended despite the collapse of the price that has taken place, there are elections only months, where negative measures are being played, and the banks are still very drastic in order to secure loans on the market."
"We think there will be more price cuts," he said.
