Housing in Sydney is becoming a self fulfilling prophecy. The more people spend on it the more it’s value increases hence attracting more investors who drive prices up.
In order for this to stop the majority of the public will need to find this whole situation unacceptable.
I find it absurd that citizens from countries that disallow Australians to buy property can buy residential property here in Sydney. Apparently helping foreign citizens to avoid taxation/capital controls while propping up the construction/banking sector is more important than looking after the average citizens best interests.
