Not really -this is what governments tend to do - they make promises that on the surface make sense, but essentially kick the can down the road far enough that by the time it is realized it is nonsensical, it no longer matters that it was their idea — exactly ! What the govt will tell you is that this will help a lot of Australians buy a home with a smaller mortgage that they can afford to repay, instead of renting for the rest of their lives ; is this really true and achievable??!!
It is not achievable this way5, because they are not encouraging real investment or ownership - a house is necessary for life - a second house or apartment is an investment.
