According to this site

Australia had 830,000 vacant homes at the last census. If we agree that China has over 50 times our population, that equates to 41.5 million houses ( 830k x 50 ). At the same time in Oz we were (and are) in a period of housing shortage driving rents and prices up.
Your concerns are a furphy IMO
